Build and customize your very own open-source button grid controller. This DIY kit comes with delicious translucent button pads, driver boards, diffused white LEDS and a custom laser cut enclosure. The result is a sturdy and elegant but also super-hackable controller device for music, video…or something else???
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!
The 8BitBox is an Arduino powered Bluetooth box, controlled via a Bluetooth enabled Android Device. This project will show you how to control an RGB LED and a piezo buzzer on an Arduino via an Android device. Once finished, you will have a customizable box that can be set to a color and play a tune from your phone. From there, you can easily start adding more features on your own, such as environmental sensors.
The BMP183 is the next-generation of sensors from Bosch, and is the fraternal twin of the BMP180 - with a low altitude noise of 0.25m and the same fast conversion time. It has the same specifications, but uses SPI instead of I2C. This is great for users where there is an I2C address collision, they want more than one sensor on a single microcontroller, more flexibility on pin usage, or just prefer the simplicity of SPI.
It's summer and you're sweating and your hair's all frizzy and all you really want to know is why the weatherman said this morning that today's relative humidity would max out at a perfectly reasonable 52% when it feels more like 77%. Enter the HTU21D-F Temperature + Humidity Sensor - the best way to prove the weatherman wrong!
You're probably familiar with SRAM, DRAM, EEPROM and Flash but what about FRAM? FRAM is 'ferroelectric' RAM, which has some very interesting and useful properties. Unlike SRAM, FRAM does not lose the data when power is lost. In that sense it's a durable storage memory chip like Flash. However, it is much faster than Flash - and you don't have to deal with writing or erasing pages.
