[Blue Blade Fish] wanted to build an Arduino-based aquarium controller. He’s detailed the system in (so far) 14 videos and it looks solid. This isn’t just a simple controller, either.

This project demonstrates an interrupt-based embedded system built using the Arduino Nano 33 IoT, a BH1750 light sensor, and a slide switch. The built-in LED is controlled through external ...

The device can control up to 8 sets of fireworks, uses a physical arm key, and has a handheld remote. It is even smart enough to sense igniter failures.

DAOKI Timer Delay Relay Module DC 6-30V Programmable Switch Control LED Display Micro USB Port Relay for Arduino with 24AWG Wire, Micro USB Cable ...

Stepper motors are mostly used for precise motion control of structures or axes for a distance. But what happens if we want to control time? We can answer this question with the bare motor rotation, ...

The Arc-Controller is compatible with about any Arduino, or other micro controller such as Raspberry Pi. It runs an ATMega328, and is user programmable via the Arduino IDE.
