Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor ...

The button states could easily be read by using an Arduino’s analog input. A Pro Mini model was chosen for its small size as it could be housed in the radio compartment of the dash.

When the Arduino code sees the button getting pressed, it brings the corresponding LED pin high and starts a fade out timer using the SoftPWM library by [Brett Hagman].

Created by the Lenka Design Workshop the case has been created using a 32×32 LEGO baseplate finished with a clear acrylic cover to house the four large arcade buttons and Arduino board, LED ...

Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

Security researchers have built a robot with one goal in mind: to crack your smartphone’s PIN. Using 3D-printed parts, servomotors, a plastic stylus, an Arduino microcontroller, and a cheap ...

As usual with Arduino, the ‘pin numbers’ aren’t the actual chip pin numbers, unless by coincidence. The led pin was correct for me, only the push button pin needed reassigning (I added a push button ...

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 ...

Unfortunately, the pins can only be used for one function at a time, so that means that when you're communicating with the computer — such as when printing data to the Serial monitor with Serial ...
