Did you know that you can use Arduino to turn on an LED when you press a button? Well, it is true, you can do this! Leaving the joke aside, let me show how you can achieve this. You will need the ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

The wiring for this project is about as easy as you’d expect: the buttons connect to the digital inputs on the Arduino, and the LEDs on the digital outputs. When the Arduino code sees the button ...

After reading all the response to the Arduino KIM emulator thing, I’m staggered by this! In case none of you have ever seen the circuit for a KIM-1, SYM-1 or AIM-1, this is pretty much how we ...

Following the circuit around from the pin 13 output we find a resistor, followed by an LED, and then a connection to the Arduino ground. When pin 13 is set to HIGH, +5 volts is supplied through ...

Features of the Arduino LED Matrix include : – Single-color 32 x 9 or 64 x 9 LED matrix display with several color options – ESP8266 controllable and programmable via Arduino ...

Then he holds up a baseball cap with LEDs stitched into the fabric. Most didn’t realize their instructor, a rising star in the DIY-electronics movement, is also a 12-year-old. “This is a Gas Cap.

Arduino is famous for empowering DIY projects, but it’s one of a multitude of choices available these days for prototyping your IoT startup, or, like, text messaging you every time your cat sneezes.
