1. Analog Rotation Brick¶
Octopus analog rotation brick is a 10K potentiometer module. Rotating the knob to change its resistance can realize voltage division, and can provide analog signals to the analog input IO ports of micro-controller. This module has a 3-wire anti-reverse connector, which makes it easy to connect a GVS cable.
Adopting 3 pins cable with anti-plug function.
No screwdriver need, the resistor can be adjusted with hand.
