Button

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.

Connections

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 or 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).
