Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...

This DIY gas leakage detector is designed for educational and basic monitoring purposes. For critical safety applications, ...

We set the potentiometer pin as 0 (A0 on the Arduino Uno board), the CONTROL variable is the voltage that is used to cotrol the led brightness of the speed of the fan. In the setup() function the ...

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 ...

If we asked you to light up an LED using an Arduino, there’s a good chance you’d know exactly how to do that. ... Finally, arrange the LEDs in an attractive circle around a potentiometer.

[Christian] wrote in to tell us about his third-generation Arduino MIDI sequencer (translated) called the AM808 VX3. He had already laid a strong base for the project in his previous versions. But … ...
