If you're here, it's because you were given the gift of electronics with an AdaBox! You are a beginner who is getting started with your AdaBox or you just want to relive what it's like being a beginner at electronics again. But most of all, you want to learn how to build and make stuff with electronics!
This FeatherWing will make it real easy to add datalogging to any of our existing Feathers. You get both an I2C real time clock (PCF8523) with 32KHz crystal and battery backup, and a microSD socket that connects to the SPI port pins (+ extra pin for CS). Tested and works great with any of our Feathers, based on ATmega32u4, ATSAMD21, Teensy, or ESP8266.
OK you've gotten your Arduino set up and also figured out how to use the software to send sketches to the board. Powerful stuff! But...just running example sketches is a little boring. What we really want to do is use our own creativity and skill to write new sketches! That's what we'll be doing in this lesson. To start we will venture deep into the Blink sketch, looking at each line and trying to understand what its doing. Then we will start hacking the sketch, and maybe even meet an internationally-famous DJ and design custom hardware for him!
Ah yes, it is finally time to make your Arduino do something! We're going to start with the classic hello world! of electronics, a blinking light. OK it doesn't sound too exciting, heck you can just flip your desk lamp on and off without needing a microcontroller.. but I promise you, you'll learn a lot!
The current generation of single board Linux machines offers an impressive amount of computer power in a tiny little space. Unfortunately, once the keyboard, mouse, display, power supplies and USB peripherals get connected up we are left with a mess of cables and hardware. Fortunately, the Pi-Top fixes the peripheral insanity and provides a 12-hour portable laptop! It's a win-win situation.
This is a quick tutorial for our 128x64 and 128x32 pixel monochrome OLED displays. These displays are small, only about 1" diameter, but very readable due to the high contrast of an OLED display. Each OLED display is made of 128x64 or 128x32 individual white OLEDs, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!
Long, random passwords are the most secure, but can be difficult to remember and tricky to type. Build this Circuit Playground Password Vault to remember and enter them for you! Store up to ten passwords and enter them into a computer over USB at the push of a button. You'll even create a unique unlock sequence so your passwords stay secure, and build a rugged 3D printed case to take it on the go.
Once you have mastered the basic blinking leds, simple sensors and buzzing motors, it’s time to move on to bigger and better projects. That usually involves combining bits and pieces of simpler sketches and trying to make them work together. The first thing you will discover is that some of those sketches that ran perfectly by themselves, just don’t play well with others. There are ways to effectively juggle multiple tasks on an Arduino. This series of guides will show you how.
Add short-hop wireless to your Feather with these Radio Featherwings. These add-ons for any Feather board will let you integrate packetized radio (with the RFM69 radio) or LoRa radio (with the RFM9x's). These radios are good options for kilometer-range radio, and paired with one of our WiFi, cellular or Bluetooth Feathers, will let you bridge from 433/900 MHz to the Internet or your mobile device.
Mu is an amazing editor that works with CircuitPython and compatible boards. You can connect to the serial REPL right inside the editor. It also includes a plotter the works with your code to give you a live visual graph of your data! This guide will show you different ways to use the plotter with different sensors. It's time to plot!
The ESP8266 based Feather HUZZAH & the HUZZAH ESP8266 breakout are both very popular options for connecting projects to Adafruit IO. In this guide we are going to walk through the setup needed to get your ESP8266 up and running with the Arduino IDE & Adafruit IO. This same basic setup can be used as you progress through our Adafruit IO Basics series of guides.
This is the Power Relay FeatherWing. It gives you power to control, and control over power. Put simply, you can now turn on and off lamps, fans, solenoids, and other small appliances that run on up to 250VAC or DC power using any Feather board. Compared to our smaller Relay FeatherWings, this one can handle a beefy 1200 Watts!
