Keyestudio Collision Sensor Module

Collision sensor, also known as electronic switch, is a digital on-off input module necessary for elementary electronic learning.
By programming, it can realize control over light, sound device, key choice function of LCD display, etc.
Using 3P sensor cable to connect it to sensor shield, it can be installed to 4WD alloy mobile robot platform to realize collision detection function. It is both convenient and efficient.
Note:
You can make a collision flasher using collision module and built-in LED on interface 13.
Connect the collision sensor to pin 3, when the collision sensor senses a collision signal, the LEDs on main board and module will light up simultaneously.
