Voltage Scaler: 60V to 5V

This voltage divider scales down voltages of up to 60V down to a max of 5V: for use with Arduino analog input pins. The high resistances mean very little power is applied to the resistors which means is it safe to use with basic 1/4W resistors. The zener diode will prevent more than 5V from being applied to the Arduino pins incase more than 60V is supplied by the battery (basic over voltage protection).
