This project combines a whole heap of modules to enable a Raspberry Pi to power a large 1.2 inch 4 digit 7 segment display. A small switch switches the display between showing the temperature and the current time. The project uses a real-time clock (RTC) to ensure that the Pi always has the correct time, even if it is not connected to the Internet.
Have a lackluster datasheet for your sensor, but a demo app from the vendor that seems to calculate the value you need? If the app is written in .Net (Visual Basic or C#) -- and if it's Windows based, it probably is -- you might be able to decompile the app and find that magic formula you're looking for!
Ever look at a pile of 10mm LEDs and think "mmm, they look just like gumdrops!" These LED gummy candies are so realistic they'll have your friends fooled at first, then delighted that they are actually edible (and delicious). This tutorial covers the basics of food-safe silicone mold making and provides a recipe for gummy candies you can make at home.
To keep costs low, the Raspberry Pi does not include a Real Time Clock module. Instead, users are expected to have it always connected to WiFi or Ethernet and keep time by checking the network. Since we want to include an external module, we'll have to wire one up. We'll go with the easy-to-use and low-cost DS1307.
Adafruit is a high-tech company, run by fairly young people. All of us working here have spent our lives with computers, technology, and the Internet. So it's not surprising that software and software-as-services (SaaS) are an essential part of running Adafruit. We're constantly on the lookout for useful new tools that can help Adafruit run efficiently, and cleanly.
New to CircuitPython? Looking for an easy way to get started? We've written a library for the Circuit Playground Express that makes it super simple to begin using all the sensors, switches and lights. This guide will show you all the features of this library and how to use each one. Let's get coding!
Your electronics can now see in dazzling color with this lovely color light sensor. We found the best color sensor on the market, the TCS34725, which has RGB and Clear light sensing elements. An IR blocking filter, integrated on-chip and localized to the color sensing photodiodes, minimizes the IR spectral component of the incoming light and allows color measurements to be made accurately.
