Description
Dual Button, as its namesake, has two buttons with different color. If the Button unit is not enough, how about double it up to a pair. They share the exact same mechanism, button status can be detected by the input pin status,simply capture the high/low electrical level.
This unit communicates with M5Core through GROVE B port.
