Wired according to the figure.
Parts
- Microcomputer Arduino uno
- Elecelet mike module
- Pump motor
- Power nMOS
- Resistor 10kohm
Arduino IDE program
I modified the program generated by the circuito.io as follows.

Operation
Place a microphone in a broken balloon and attach a balloon to the motor. Blowing a broken balloon inflate the other balloon.
