long current_time = millis(); //millis() - Returns the number of milliseconds since the Arduino board began running the current program. bool btn = digitalRead(BTN ...

This is an exercise in designing a PCB and taking it through to manufacture. This project is inadvertantly on hold for now, but I'd say it went pretty well for a first go. :D Successes: I really ...

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 ...

This is a project circuit in which we use PWM to dim the intensity of light of the LED. The Pulse Width Modulation (PWM) plays an important role in controlling the circuits. If you want to control the ...

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 ...

Like many FPGA beginners, one of my first tutorials was the classic “turn on an LED” project. While a great starting point, I wanted to explore further. I also found the LED far too bright! This led ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

A switch is the most essential part of any circuit. Different circuits use different switches in them. In this project, we are going to use a Touch Dimmer Switch. This switch is a touch-sensitive ...
