PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

[SeanHodgins] has a project in mind where he needs to sample over 500 analog sensors. To get ready, he made a breakout board for 32-channel analog multiplexer device he wants to use. He put the pro… ...

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 ...

Plug that into your Arduino and boom, temperature (and humidity!) readings. But the simple solution doesn’t hit every need, sometimes things need to get more esoteric.

The Arduino Nano and Raspberry Pi Pico have distinct pin configurations. The Nano includes 14 digital pins (for both digital input and digital output components) and eight analog pins. Six of ...

When we began this series, we observed that board-level designers often have concerns about the proper way to handle grounding for integrated circuits that have separate analog and digital grounds.

We’ve taken the versatile processor behind the Arduino Leonardo, and combined it with a Direct Digital Synthesis chip, which makes generating analog signals incredibly straightforward. Then, we ...
