Enter the ExtraCore library for Arduino, a software library that turns two or more Arduinos into a multi-core microcontroller with more pins than you’ll ever need.

If you've got an Arduino of any variety, you might have noticed some of the pins on the board have a tilde mark or PWM printed next to them. What is PWM?

He put the project out on Hackaday.io and also has a video tutorial you can see below. There are five input pins to the chip which lets you connect one analog pin to any one of 32 analog pins.

Now it is clear, a MCP9700A temperature sensor connected to the Arduino analog input pin A1 is used to measure temperature. The Arduino sketch for the experiment handles the inputted data and displays ...

Keyestudio UNO R3 development board is a microcontroller board based on the ATmega328P (datasheet), fully compatible with ARDUINO UNO REV3. It has 14 digital input/output pins (of which 6 can be used ...

The analog sensor on the Arduino board senses the voltage on the analog pin and converts it into a digital format that can be processed by the microcontroller. Here, we are feeding the input voltage ...

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 ...

This library is used in order to abstract away a few of the details to do with analog multiplexing and demultiplexing. It assumes the following: The multiplexer is analog and is compatible with the ...
