Need help to make a project Answered
I need to build a project where a proximity sensor of a person (1 - 3 ft) would cause a very small motor to press a plastic bottle once per cycle. The cycle should only be able to be activated once between 10 - 15 minutes. The soft plastic bottle would be no more that 2 - 4 cm diameter 7 - 8 cm long with a tube connected to it's tip and the bottle would be inverted to allow gravity to allow the liquid to move down the tube. The idea is to get just 1 drop to drip from the tube. I would want the power source to be a rechargeable AA 1.4v up to 8 - 9v rechargeable battery. This will be my first electronics project so please keep it as simple as possible.
