[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… ...

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 ...

The MOSbius chip [top left] contains all the transistors required for many analog systems. Mounted on a breadboard via a ...

The junction on the voltage divider network connected to the the Arduino analog pin is equivalent to the input voltage divided by 11, so 55V ÷ 11 = 5V. In other words, when measuring 55V, the Arduino ...

I connected one soil probe to power, and the other to ground through a 10kΩ resistor and to Arduino's analog pin A0. I did the same with the thermistor and photoresistor, but connected those to ...

To get started with learning Arduino, you'd first need to have the essential hardware materials on hand — at the top of the list is the Arduino board itself. There are several variations ...
