Quick note: ATmega based Arduino boards (UNO, Nano, Mini, Mega) takes about 100us to read an analogue input, so the maximum reading rate is about 10,000 times second. Below you can see a “CIE1931 Fade ...

Figure 4 Schematic of the string lights-to-LED adapter where the 5v is supplied by a USB connection to the Arduino Nano and the potentiometers are connected to the three analog inputs to digitally ...

This was helped further thanks to the use of transistors to run the LEDs directly from battery voltage, rather than obeying the current limits of the Arduino Nano’s output pins.

Here's an interesting way to control an Arduino using data-over-sound, demonstrated by Chirp. They show how to use their SDK to send an RGB value to change the colour of a on-board LED.

Reddit user Krukerfluk has created an awesome DIY digital clock using 144 x seven segment displays, combining them to create a larger LED display powered by an Arduino Nano.

Fancy making a cool looking magnetic levitating lamp? Check out this Arduino Nano-based project that combines a magnet and LEDs.

All the info you need right here ✦ In this occasion I'll make a lighting system to be controlled remotely from my rc using Arduino compatible boards, they will take the input from a receiver and ...

Arduino Maker Nano RP2040 “Slightly shorter than a Pico, this board has 30 pre-soldered pins, all helpfully labelled on the silkscreen.

Inside, an Arduino Nano is hooked up to a series of WS2812b LEDs. The LEDs are flashed in time with the heartbeat of the person holding the heart, thanks to a MAX30102 heartbeat sensor.
