# Simple Vertical Wordclock ## Overview ## Vertical Clock This simple vertical version on the ever-popular wordclock spells out the time by illuminating rows of words. Reading from top to bottom, any five minute increment of time can be spelled out by illuminating some combination of these rows. (Credit to Twitter user [@3d0g](https://twitter.com/3d0g/status/1141740187011223552) for this concept.) This project uses a laser engraved piece of acrylic paired with a cardboard stand and is lit by a strip of [NeoPixels](https://www.adafruit.com/) powered by a [Feather M4 Express](https://www.adafruit.com/product/3857) board with a [Precision Real Time Clock FeatherWing](https://www.adafruit.com/product/3028) keeping time even if the clock is disconnected from power.  ![](https://cdn-learn.adafruit.com/assets/assets/000/078/177/medium800/feather_boards_word_clock_demo_ORIG_2019_07.jpg?1562963104) ### Adafruit NeoPixel LED Side Light Strip - Black 60 LED [Adafruit NeoPixel LED Side Light Strip - Black 60 LED](https://www.adafruit.com/product/3636) Fancy new _side light_ LED strips are a great alternative for folks who have loved and used Adafruit LED strips for a few years but want gorgeous, glowy light emitting at 90 degrees.

Follow the diagram below to see how the circuit is constructed. This circuit includes an optional switch that will allow the user to toggle the clock daylight savings time (+ one hour).  ![](https://cdn-learn.adafruit.com/assets/assets/000/078/134/medium800/circuitpython_wordclock2_bb.png?1562940257) Start building this circuit by connecting the power and GND lines to the terminal blocks on the DC power adapter. ![](https://cdn-learn.adafruit.com/assets/assets/000/078/042/medium800/circuitpython_IMG_5693.jpg?1562797401) ## Solder Time The Feather needs [Female headers](https://www.adafruit.com/product/2886) soldered on. Solder male headers (included with the 'Wing) onto the RTC FeatherWing. Solder the jumper cables from the terminal block to the Feather M4 and Featherwing. Plug RTC FeatherWing into Feather M4 Express. ![circuitpython_IMG_5695.jpg](https://cdn-learn.adafruit.com/assets/assets/000/078/061/medium640/circuitpython_IMG_5695.jpg?1562865369) ![circuitpython_IMG_5699.jpg](https://cdn-learn.adafruit.com/assets/assets/000/078/062/medium640/circuitpython_IMG_5699.jpg?1562865488) ## Flexible Power Source This circuit arrangement will allow you to conveniently power your clock via a micro USB cable or a 5V DC power supply interchangeably. The small coin cell battery in the RTC FeatherWing will keep time for you even if the clock is unplugged, so you never have to worry about setting the time. ![](https://cdn-learn.adafruit.com/assets/assets/000/078/010/medium800/circuitpython_IMG_5661.jpg?1562787765) ## Daylight Savings Time To account for the spring forward and fall back cycle we go through every 6 months, a small switch can be added to the circuit to allow the user to toggle the time forward an hour and back when needed. ## Toggle Switch Bend the legs of the slide switch 90 degrees.   Solder one wire from the middle leg of the switch to the GND line.   Connect the left leg of the switch to pin #6 on the RTC FeatherWing. ![circuitpython_IMG_5710.jpg](https://cdn-learn.adafruit.com/assets/assets/000/078/101/medium640/circuitpython_IMG_5710.jpg?1562882420) ![circuitpython_IMG_5714.jpg](https://cdn-learn.adafruit.com/assets/assets/000/078/103/medium640/circuitpython_IMG_5714.jpg?1562882541) ![circuitpython_IMG_5715.jpg](https://cdn-learn.adafruit.com/assets/assets/000/078/105/medium640/circuitpython_IMG_5715.jpg?1562882763) Now, flipping this switch to the left will activate Daylight Savings mode, adjusting the clock one hour forward.  ![](https://cdn-learn.adafruit.com/assets/assets/000/078/100/medium800thumb/circuitpython_IMG_5718.2019-07-11_17_55_18.jpg?1562882269) # Simple Vertical Wordclock ## CircuitPython ## Getting familiar with CircuitPython [CircuitPython](https://learn.adafruit.com/welcome-to-circuitpython/what-is-circuitpython) is a programming language based on Python, one of the fastest growing programming languages in the world. It is specifically designed to simplify experimenting and learning to code on low-cost microcontroller boards. CircuitPython is easiest to use within the Mu Editor. If you haven't previously used Mu, [this guide will get you started](https://learn.adafruit.com/welcome-to-circuitpython/installing-mu-editor). ![](https://cdn-learn.adafruit.com/assets/assets/000/077/951/medium800/makecode_circuitpython_circuit_playground_adafruit_blinka_computer.png?1562630471) ## Preparing your Board 1) Download the [latest 4.0 library pack](https://github.com/adafruit/Adafruit_CircuitPython_Bundle/releases/), 2) Unzip it the library pack and drag the  **adafruit\_bus\_device** , **adafruit\_ds3231** , **adafruit\_register** , and **neopixel** libraries over into the  **/lib**  folder on  **CIRCUITPY**. If there is no  **lib**  directory on your CIRCUITPY drive, create one to put the file into. More info on installing libraries can be found [here](https://learn.adafruit.com/adafruit-circuit-playground-express/circuitpython-libraries). Make sure you have the following libraries installed:  - **adafruit\_bus\_device** - **adafruit\_ds3231** - **adafruit\_register** - **neopixel** ![circuitpython_Libraries-setclock.png](https://cdn-learn.adafruit.com/assets/assets/000/078/063/medium640/circuitpython_Libraries-setclock.png?1562866341) ![circuitpython_Screen_Shot_2019-07-10_at_3.47.34_PM.png](https://cdn-learn.adafruit.com/assets/assets/000/078/064/medium640/circuitpython_Screen_Shot_2019-07-10_at_3.47.34_PM.png?1562866367) ## Setting the Time First things first, let's tell the RTC FeatherWing what time it is!  Copy and paste the code below into Mu. In line 22, fill in the correct year, month, day, hour, and minute. Save this as **code.py** to your **CIRCUITPY** device. (More details on using the DS3231 Precision RTC can be found in [this guide](https://learn.adafruit.com/adafruit-ds3231-precision-rtc-breakout/circuitpython)) https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/CircuitPython_Simple_Wordclock/set_clock/code.py Once the time has been set we're ready to move on to uploading the Wordclock code. ## Vertical Wordclock Code Make sure you've connected the Feather M4 Express to your computer (mac/PC/Linux) via a known good USB A to micro-B cable. Your board should show up as a flash disk drive named  **CIRCUITPY**  (If you see a disk name **FEATHERBOOT** , try pressing the reset button again. If the only drive name you get is named  **FEATHERBOOT** , CircuitPython may not be loaded on the board. You can load CircuitPython as [per this guide](https://learn.adafruit.com/adafruit-circuit-playground-express/circuitpython-quickstart)). Once your board is connected, copy the code below from the window below to a file on the Feather **CIRCUITPY** drive as **code.py**. You can select **Download** in the upper left to save the code onto your computer. https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/CircuitPython_Simple_Wordclock/code.py Open the code up in the Mu editor. Press the  **Save**  button and your code should automatically be saved to the  **CIRCUITPY**  disk drive (which appears when the Feather M4 Express is plugged into your computer) as  **code.py**.  ![](https://cdn-learn.adafruit.com/assets/assets/000/077/952/medium800/circuitpython_Screen_Shot_2018-09-06_at_9.47.58_AM_copy.png?1562630479) Info: ## Making Changes If you'd like to adjust the color of your clock, this can be changed in **line 29 ** of the code. Simply change the numbers in `COLOR = (0, 200, 0)` (green) - make the clock glow blue (`0, 0, 200`) or red (`200, 0, 0`), or any color in between! A great color picker is at [https://www.w3schools.com/colors/colors\_picker.asp](https://www.w3schools.com/colors/colors_picker.asp). # Simple Vertical Wordclock ## Laser Cutting The face of this clock is made from a piece of acrylic that's engraved and cut so as to contain the light from each NeoPixel so that each word glows distinctly. [Vertical_Wordclock.ai](https://cdn-learn.adafruit.com/assets/assets/000/078/050/original/Vertical_Wordclock.ai?1562802565) This file has the words spaced to align with the spacing between each NeoPixel, 0.656" between centers. The words are engraved, the outlines cut. ![](https://cdn-learn.adafruit.com/assets/assets/000/078/085/medium800/circuitpython_Screen_Shot_2019-07-11_at_5.28.52_PM.png?1562880594) ![](https://cdn-learn.adafruit.com/assets/assets/000/077/958/medium800thumb/circuitpython_Untitled.2019-07-08_16_01_11.jpg?1562632370) # Simple Vertical Wordclock ## Build the Clock The frame for your clock can be as simple or as fancy as you wish. Here, a minimalist and inexpensive option is shown, creating a thin channel in which to hold the NeoPixel strip and a small cardboard base to keep it standing. ## NeoPixel Channel Cut three long, thin strips of cardboard. Glue them together to create a channel that will hold the NeoPixel strip. Lay the NeoPixel strip into the channel to test its fit. ![circuitpython_IMG_5432.jpg](https://cdn-learn.adafruit.com/assets/assets/000/077/939/medium640/circuitpython_IMG_5432.jpg?1562629025) ![circuitpython_IMG_5433.jpg](https://cdn-learn.adafruit.com/assets/assets/000/077/940/medium640/circuitpython_IMG_5433.jpg?1562629056) ![circuitpython_IMG_5435.jpg](https://cdn-learn.adafruit.com/assets/assets/000/077/941/medium640/circuitpython_IMG_5435.jpg?1562629073) ![circuitpython_IMG_5436.jpg](https://cdn-learn.adafruit.com/assets/assets/000/077/942/medium640/circuitpython_IMG_5436.jpg?1562629091) ## Clock Foundation   Cut three rectangular sections of cardboard. Make a small square hole through two of them and cut a longer channel out of the third. Glue the three pieces together, putting the channel on the bottom ![circuitpython_IMG_5444.jpg](https://cdn-learn.adafruit.com/assets/assets/000/077/943/medium640/circuitpython_IMG_5444.jpg?1562629300) ![circuitpython_IMG_5446.jpg](https://cdn-learn.adafruit.com/assets/assets/000/077/944/medium640/circuitpython_IMG_5446.jpg?1562632431) ![circuitpython_IMG_5448.jpg](https://cdn-learn.adafruit.com/assets/assets/000/077/945/medium640/circuitpython_IMG_5448.jpg?1562629866) ![circuitpython_IMG_5445.jpg](https://cdn-learn.adafruit.com/assets/assets/000/077/946/medium640/circuitpython_IMG_5445.jpg?1562632447) Warning: ## Bring it Together Glue two strips of cardboard on the base to hold the bottom of the acrylic in place. Use hot glue to affix the NeoPixel channel to the base, centering it over the hole cut for the the strip. Thread the NeoPixel strip through the hole in the base, pulling it all the way through so the last pixel is at the top of the channel. _Keep in mind the bottom pixel will be hidden in the base of the clock_; it is ignored in the code, this is ok. Add two more strips of cardboard to the bottom of the base, pinning the end of the NeoPixel strip so that it comes out the back. ![circuitpython_IMG_5644.jpg](https://cdn-learn.adafruit.com/assets/assets/000/078/007/medium640/circuitpython_IMG_5644.jpg?1562786015) ![circuitpython_IMG_5649.jpg](https://cdn-learn.adafruit.com/assets/assets/000/078/008/medium640/circuitpython_IMG_5649.jpg?1562786035) ![circuitpython_IMG_5618.jpg](https://cdn-learn.adafruit.com/assets/assets/000/078/009/medium640/circuitpython_IMG_5618.jpg?1562786118) ## Add Acrylic Slot acrylic piece into place. ![circuitpython_IMG_5646.jpg](https://cdn-learn.adafruit.com/assets/assets/000/078/004/medium640/circuitpython_IMG_5646.jpg?1562785818) ![circuitpython_IMG_5650.jpg](https://cdn-learn.adafruit.com/assets/assets/000/078/005/medium640/circuitpython_IMG_5650.jpg?1562785883) As a final touch, once the acrylic piece is in place, add a dab of hot glue to the top to keep the acrylic held tightly against the the NeoPixel strip. ![](https://cdn-learn.adafruit.com/assets/assets/000/078/006/medium800/circuitpython_IMG_5654.jpg?1562785980) Power on your clock and you should see the time pop up! ![](https://cdn-learn.adafruit.com/assets/assets/000/078/106/medium800thumb/circuitpython_wordclock_demo_long.2019-07-11_18_12_51.jpg?1562883207) ## Featured Products ### Adafruit NeoPixel LED Side Light Strip - Black 60 LED [Adafruit NeoPixel LED Side Light Strip - Black 60 LED](https://www.adafruit.com/product/3636) Fancy new _side light_ LED strips are a great alternative for folks who have loved and used Adafruit LED strips for a few years but want gorgeous, glowy light emitting at 90 degrees.
