This firmware (arduino pro micro sketch) is intended for small productions of leds based devices. It is compatible with ATmega32U4 with Arduino bootloader (Arduino pro micro, Arduino leonardo) This ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...

Animate multiple 24 VDC LED garlands with flashing and variable brightness (13 different parameters) with one Arduino Nano multi-tasking with FreeRTOS.

Our project is infact an Arduino with Serially Interfaced MAX7219 Operates an 8X8 LED Matrix to display a heart pattern. The MAX7219 IC is a serial input/output common-cathode display driver that ...

The RGB LED module lets you make all sorts of colors with just four pins from the Arduino. Learn how to do it here!

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

Welcome to our blog post on interfacing the WS2811 (5V) RGB LED strip with Arduino! In this guide, we will walk you through the process of connecting and controlling WS2811 LED strips using an Arduino ...

If the upload is working, you should see the RX and TX lights on the Arduino flash - and then your program will start to run. Congratulations - you've just developed a stand-alone electronic gadget.
