Clap Contorled Zipliner Robot
The idea:
In this project, the robot's motor activates shortly right after a clap
is heard from the microphone module. The idea is that you need to clap
constantly in order to move the robot across the zipline so that the
faster you clap the faster it goes.
The circuit:
- In this circuit, an Arduino nano is used. Any other types of Arduino
can be used of course but do not forget to change the pin configurations
if you want to change the circuit on your preference.
