Looking for a simple circuit ... Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated (PWM) channels to fulfil your ...

The blinking frequency of the LED depends mostly on the RC time constant (in this case T = 11 seconds). The capacitor’s voltage must be a little bit higher than the diac’s breakover voltage. I love ...

As you can see from that sketch and the circuit diagram, the LED is connected to the digital pin 13 of the Arduino. Once you verify (compile) the sketch and upload it to the Arduino board, you should ...

The processor has been verified as working with a blinking LED. It’s the ‘Hello World’ of computer design, and it’s at least as complex as blinking a LED with an Arduino. You’re gonna ...

It is a pretty common first project to use an Arduino (or similar) to blink an ... view of the LED. You might use this as a safety light that only works in the dark. A simple circuit, but it ...

If you're looking for a fun electronics project to give a small fright to trick-or-treaters you can create a spooky blinking ... LED eyeballs, an ATtiny85 microcontroller, and an Arduino.

He describes how he programmed the lights to blink when the sensor ... how to build squishy circuits with LEDs and a heartbeat-sensor pendant using LilyPad, an Arduino microcontroller board ...
