Hand control fan

Hey everyone. Are you a lazy? If yes then we all have experienced the high gravity when we are waking up. The problem comes when you are sweating in bed and you want to increase the fan speed. The tendency to sleep and the wish to increase the speed both come at the time. So we need a fan that can be controlled by hand. That’s what we are going to do.

Connections:

One pin of all 10 dc motors to 2, 3, 4, 5, 6, 7, 8, 9, 10, 11

Another pin of all 10 dc motors to GND

SCL of accelerometer to A5 of Arduino

SCA of accelerometer to A4 of Arduino

GND of accelerometer to GND of Arduino

VCC of accelerometer to VCC of Arduino

Precautions:

1) Attach a plastic fan to all motors

2) Make sure that all motors give air and don’t suck air if it doesn’t happen then exchange its connections

3) (Optional)To get cool air make sure air passes through ice cold water

how to use:

1) attach sensor to your fore arm and rotate it
