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 ...

The build is open-source, and designed to work with strings of 60, 120, or 180 WS2812B LEDs. An Arduino Nano is charged with running the show, capturing audio via its analog-to-digital converter.

“I’ve built a digital clock made out of 144 seven-segment displays controlled by an Arduino Nano. The segments are controlled by 18 MAX7219 ICs which can control up to 64 individual LEDs or 8 ...

Other features of the Maker Nano RP2040 small board which measures just 49.53mm x 21.08mm in size include support for the Arduino IDE, CircuitPython and MicroPython.

The ShakeIt light fixture consists of an Arduino Nano clone, NRF24L01+ with SMA Antenna, buck converter, 74 addressable RGB LED’s, and a bluetooth module. The bluetooth module connects to a ...

Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...

The mod works using a MAX7219 chip and Arduino Uno ATmega328 board, which control the two 8×8 LED matrixes making up the eyes. Each matrix is wired up to the MAX2719 chip–expect a lot of cables ...

Arduino has announced four new Nano microcontroller-based boards that will be available for developers and makers in late July. See also 'We thought we'd sell 1,000': The inside story of the ...
