Circuit Connections Connect the common ground of the LED array to the GND pin of the Arduino Uno. Connect the positive terminal of each LED to a separate digital pin (0-7) on the Arduino Uno. Insert a ...

This is an alternative approach to the code for the Arduino Twinkle Lights project. You can find a complete project write-up at johnwargo.com. For the original project, I used two strands of lights, ...

In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a laser pointer.

[Trent M. Wyatt]’s CPUVolt library provides a fast way to measure voltage using no external components, and no I/O pin. It only applies to certain microcontrollers, but he provides example Ar… ...

This paper presents a wireless sensing platform for Industrial applications such as Industrial 5.0. It uses Xbee S2C and Arduino Due/ESP32 for wireless communication and offers customizable data ...

We got it running on an Arduino Leonardo the quickest, because it has support for Serial1(). Don’t be discouraged by these glitches in this rev 0 deployment — [Eric] has really made quite a ...

Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small ...
