Feature

Arduino will turn on the compressor and pressurize until max pressure is reached
Arduino will also serial write the pressure it is reading
Arduino will open the valve to bend the leg when only the valve button is pressed
Arduino will also close the valve if the valve is opened for 5 seconds

How to Test

upload the code using the arduino IDE if not uploaded on the arduino already
Check to make sure the following is satisfied
- The valve next to the compressor is closed
- The leg is properly attached
Turn on the board using the big switch
Open the serial monitor (pressure reading should be seen)
Wait for the system to pressurize
Once pressurized check to make sure 82 psi is reached
Press on the valve button
the muscle should inflate
the compressor should turn back on if the lower than ideal pressure
Once the muscle is inflated for 5 seconds the valve will close
pressing on the valve switch past this point will cause the muscle to inflate again
When the muscle is inflated and both the compressor button and the valve switch is pressed then the valve should close
Only pressing on the compressor button will cause the compressor to turn and overwrite the system
