Exploring a vintage single digit seven segment display with an Arduino Nano Flip. Mapping segments and running counting and chase light modes for fun.

Ambient-Adaptive BLE Particulate matter Monitor

Create glowing eyes for your costume! This project is ideal for any character with glowing eyes, like the Black Mage from Final Fantasy, Jawa from Star Wars, or Orko from He-Man.

Build a diy Meshtastic node using Meshtastic ESP32 and LoRa devices for secure, long-range, encrypted mesh messaging, perfect for off-grid communication.

This guide shows how program these crafty monsters with both Microsoft MakeCode - a block-based programming system that's easy for anyone to use, and CircuitPython, a Python-based language that is the perfect introduction to higher-level programming.

This module from Elecrow has endless possibilities for making DIY projects in a relatively simple way, without the need for soldering or other hardware work.

This tutorial walks you through a tiny, privacy-first web app that reads only the advertised CO2 level from a nearby HibouAir sensor using a BleuIO USB BLE dongle. Renders it as a color bar with a simple “High CO2” warning when your threshold is crossed.

Here is a quick project for an electronic Halloween pumpkin.

This project successfully demonstrates that the Unihiker K10 board, despite being AI-oriented, can effectively utilize standard Arduino libraries for creating traditional electronics projects.

Build a DIY USW indoor positioning system Using ESP32 with the Qorvo DWM3000. This tutorial walks you through hardware, firmware, and Python visualization to create accurate tracking for robotics and IoT projects.

Do you need a last-minute Halloween decoration to scare your friends and trick-or-treaters? Try building a scream box that lets out blood-curdling screams when it's opened!

For social distant trick or treating, we thought we’d make a BLE controlled servo claw using the Circuit Playground Bluefruit.
