A small noise/drone synth with percussion mode. Made using the Mozzi library and two Arduino Nanos.

A morphing digital clock

Visualizes the peak of frequencies with different bars on 8*8 led dot matrix using Arduino Nano.

VFO/RF generator for use in homebrew radio equipment such as direct conversion and superheterodyne receivers or ham transmitters.

Turn your melodica into a compressed-air melodica controlled by Max and Arduino. It tries to follow the melodic contour it listens to!

Following the principle of the original Roulette, the movement of the LED simulates a ball whose speed gradually decreases until it stops.

Program an AVR-IoT WG board externally instead of the onboard debugger. I had to workaround as I bricked my nEDBG debugger on my AVR-IoT WG.

I'll show you how to make a 2-Wheel Bluetooth Controlled Car based on an Arduino Nano.

A simple setup using an Arduino Nano and an LCD Keypad Shield to set the date, time and alarms for a DS3231 Real Time Clock (RTC).

An easy DIY lamp which can change its colour like a chameleon. Just show it a different colour & see the magic.

Pulse induction Metal Detector. It can detect a metal coin at a distance of 15 cm and a larger metal object at a distance of 40 cm and more.

Drive without distracting your sight, take care of speed limits, "f****" speed traps taking under control your car speed on windscreen!
