An initial project using Alchitry's onboard FPGA to manipulate PWM

A simple guide for configuring the PATH variable on Win 10, Mac OSX, and Linux systems.

Get up and running quickly with this simple to use UV sensor.

Here are a few tips in using the PicoBoard with Scratch v1.4. The PicoBoard allows us to write Scratch programs that interact with a variety of sensors on the PicoBoard. These sensors include: sound, light, a slider, a push button, and 4 external sensors (A, B, C, and D).

Monitor the weather without being exposed to it through wireless communication between two micro:bits using the radio blocks! This is useful if your weather station is installed in a location that is difficult to retrieve data from the OpenLog. We will also explore a few different ways to send and receive data.

Get started with the SGP40, BME280, VCNL4040, and microOLED via I2C using the Qwiic system and Python on a Raspberry Pi! Measure VOC Index, light, temperature, humidity, and pressure from the environment. Then display them on the microOLED, serial terminal, or the cloud with Cayenne!
