* 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 ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

The real-life closeup image of a WS2812B LED is given below. You can see that the WS2812B die is connected to 3 individual LEDs namely Red, Green and Blue using gold wires. The video below shows the ...

Simple RGB Strip Controller is as the name implies, a very simple RGB strip controller and is built on the Arduino platform. This controller accepts very simple commands via the Arduino's serial port ...

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

The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...

The art of taking long exposure photographs with blinking RGB LEDs has improved greatly over the years, mostly due to the extremely easy to use Arduino and hundreds of tutorials on the web. If there’s ...

Before explaining the PWM generation on ESP32, let’s discuss some terms associated with PWM. TON (On Time): The duration of time when the signal is high. TOFF (Off Time): The duration of time when the ...
