Reference
recvADC(channel)
This function has only one input parameter, which can be 0, 1 or 2.
When the input is 0, the value of this function is the voltage value of the left photoresistor.
When the input is 1, the value of this function is the voltage value of the right photoresistor.
When the input is 2, the value of this function is the voltage value of each battery. After multiplying by 3,
it is the actual battery voltage value
