Iridium Satellite Communication with Arduino

When deploying a microcontroller-based IoT solution or just doing experiments gathering data in the field, you often need a way to get the data back to your home base or to the cloud somehow. You’ve probably used WiFi, maybe dabbled with cellular solutions, but...

Arduino Audio Hacker Realtime Voice Changer

Here’s another fun but simple project using the Audio Hacker shield for Arduino. This is a realtime voice changer, which is an improvement upon the original voice changer example I provided with the Audio Hacker library. This project uses a technique...

Arduino Audio Hacker Realtime Reverser

Here’s a fun project using the Audio Hacker shield for Arduino – a realtime audio reverser! This program records the audio input to the Audio Hacker’s memory but plays it back in reverse. The “play head” jumps ahead a bit, then plays...

Wi-Fi Camera Trap

Project source code at GitHub: wifi-camera-trap We have lots of small wildlife around our house (mostly rabbits this year) and since I have a small camera module and a cheap PIR (passive infrared) motion sensor, I thought it would be fun to make a motion triggered...

Individually Addressable Incandescent Lamps

Everyone playing with electronics these days knows about LED strips made of dozens or hundreds of individually addressable RGB LEDs. I love them and make great use of them in the nootropic design Lumazoid music visualizer. But what about incandescent lamps? Old-school...
