Project 4
Let us Say "No" bravely!
- Project Description -
Say No —— A remote control device for controlling finger shaking
Put the servo in the finger made of ultra-light clay,
and the infrared remote control can control it to start shaking and stopping.
MODE 1 : DEFENSE BUFF——>NO;
MODE2 : RIDICULE BUFF——>YOU CAN NOT DO IT
