I had a working bluetooth controlled car made with arduino uno, L293 motor driver shield. After many months, i tried to use it but now there is no +5V on the board which was used to supply power to the bluetooth module HC-05. I checked and the power supply from 3 li ion batteries is 12.6V while the onboard +5V shows only 0.5mV?
