* This sketch shows you how to drive a 12V LED strip using a TIP122 Darlington transistor. * The sketch makes the strip LEDs to fade on and off using Pulse Width Modulation. * Use any PWM-capable pin ...

* This sketch shows you how to drive a 12V RGB LED strip using a TIP122 Darlington transistor. * The sketch makes the strip RGB LEDs to show random colors. * This is done by producing random PWM ...

This is a where a Power Mosfet comes in. With the help of the Power Mosfet, we can use the low voltage output from the Arduino ports to control high voltage/current loads -the popular “12V LED strips” ...

What if we can generate different colors using a single RGB led and make our room’s corner more attractive? So, here is a simple Arduino based color mixing lamp which can change color when there is ...

In this DIY project tutorial we are going to use a 32x16 LED dot Matrix display module which is also known as P10 LED Display Module to display a scrolling text by using Arduino UNO. P10 modules can ...

We show how to use an ESP8266 RGB LED strip controller with open source Arduino sketch handling MQTT messages, and an HTML5 web interface.

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 ...

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

This Automatic Battery charger circuit can be used to charge a 12V, 7Ah battery, or above. The charger maintains float voltage, if battery is fully charged.
