Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.

Arduino (I have the chineese clone of Nano) D9 pin as PWM output A0 pin as analog input (for current feedback) GND pin just for GND. R - resistor for current measurement (I have 470 Ohm, I think ...

Fades the D9 pin from 0V to 5V with 0-65535 levels, then back to 0V again. There are a total of 65536=2^16 levels, not the default 256=2^8 levels that analogWrite provides. The 8-bit nature of the ...

In this tutorial we discussed the Sound sensor, its pinout, working, and how to interface it with Arduino. This article includes a complete Arduino code and circuit diagram along with a step-by-step ...

Not long after [CulinarilySpeaking] got into the Arduino game, he began to want more IO pins and a larger program space for more ambitious projects. This, of course, led him down the path towards ...

[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… ...

In this tutorial we use SPI Protocol for communication between two Arduinos. Here one Arduino will act as Master and another one will act as Slave, two LEDs and push buttons will be connected to both ...
