Arduino Power Off Relay at Tayla Hamlyn-harris blog

Arduino Power Off Relay. Wiring arduino and the relay board. Assuming it's like my relays, that relay can either power the relay coils and the logic inputs, or (if you remove the jumper) use separate power for the relay coils and the logic signals. This means the relay is taking power from the arduino. The problem is when i connected vcc or gnd (relay) to 5v or gnd (arduino), the arduino power is off. Please see parts list for a complete list of components required. It is unclear, if you want to power off the arduino in regular operation, or if you just want to save the time settings in case of a power outage. Relay to arduino in to d7 gnd to gnd vcc to 5v. 1) take a jumper (dupont cable) and connect one end to pin 7 of arduino. In the code i posted, you can turn the relay (ledpin) on by sending '1' and off by sending '0', and if nothing is received for 3000. When i disconnected them the arduino.
