One problem with all those Arduino variants is, that the pins are different between them. Most of the example sketches are written for the Uno, which is the most common variant. And often the pin ...

I wanted to try the Low Voltage Labs Traffic Lights for Arduino and Breadboards using a couple of different types of Arduino that I had on hand:. Arduino Uno: Ideal for trying the lights by plugging ...

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 ...

This course provides a hands-on introduction to the world of Arduino and microprocessing. Students will use the Arduino UNO board and by the end of the course program their first sketch (program). The ...

The circuit is quite simple: an LED with 100 Ohm resistor is connected to the “5V” output of the Arduino and the Arduino’s pin “3”. When pin “3” outputs a “LOW” voltage, current flows through the LED ...

I’m always a little surprised that we don’t see more ARM-based projects. Of course, we do see some, but the volume isn’t what I’d expect given that low-level ARM chips are c… ...
