These buttons have a built-in 10kΩ pulldown resistor. You can connect them directly to your Arduino/Genuino Uno or Mega, or a breadboard, without soldering using the pins attached to the leads, and then control them from MECControl.


The blue lead may be connected to any of the digital pins on your Arduino/Genuino Uno or Mega, labelled 2-13 on the Uno and 2-53 on the Mega. They can also be connected to any of the analogue pins, labelled A0-A5 on the Uno and A0-A15 on the Mega .

The red lead should be connected to a 5V DC power supply, with the black lead connected to ground (a voltage of 0V).
