This is a another version of a music LED strip using Arduino Nano and an Electret Mic/Max4466 Amplifier.

A stereo VU meter built with an Arduino Nano and two NeoPixel LED rings.

This project is for making a 32-band audio (music) frequency spectrum analyzer / visualizer using Arduino.

Arduino Nano 32x8 LED matrix displaying date, time, temperature and humidity with a motion sensor.

Scan and draw ruff sketch of distances ahead just like RADAR using UltraSonic Distance Sensor.

Make an interactive table that displays games, an audio spectrum, and animations on a 12x12 built-in LED matrix.

Step by step approach is followed so that any hobbyist or design engineer can have a better understanding of the basic concepts.

A Lego arachnid controlled by your smartphone.

Another indoor greenhouse powered by Nano. 100% controlled environment with some extra perks that make life easier.

Imagine being outside cell phone range. How do you broadcast where you are for help? Enter an APRS tracker to broadcast location info.
