                                        To connect a 12V relay to the Arduino you need the following things: - 1 Arduino - 1 diode for example 1N4007 - 1 NPN transistor for example 2N2222... ... We are going to measure the coil resistance to calculate the current. First we must find the coil: O...看更多
