Arduino Resets When Signal Sent To Relay General Guidance Arduino Forum

Arduino Resets When Signal Sent To Relay General Guidance Arduino Forum When i connect the arduino and relay board as shown in the diagram below (without motors connected), and a signal is sent to the relay, it operates fine (relays click on and off). once i connect the motors and send the signal, the lights on the relay flicker and click once the arduino resets. Every time the arduino triggers the relay, 12vdc is sent to the locks and they energize like the should. once the locks are energized, the arduino rests itself.

Arduino Resets When Signal Sent To Relay General Guidance Arduino Forum The power ground glitches are causing your mcu to generate an internal reset signal which makes it start its program over again. there are some things you can do to improve the situation:. Try putting a back emf diode across the relay coil to supress the large back emf generated when it is switched on and off. it is mostly causing a spike on the arduino supply line causing the reset. also make sure the supply feeding the relay is adequately decoupled. If relay actuates, it may be you don't have the flyback diode connected properly to protect the arduino and transistor. that could cause a reset when the relay is turned off. When relay is turned on or off arduino resets (sometimes) that's typical for a missing kick back diode on inductive loads. post schematics. using pen and paper surely does well.

When connect arduino , relay board shown in diagram below (without motors connected), , signal sent relay, operates fine (relays click on , off). once connect motors , send signal, lights on relay flicker , click once arduino resets. if connect separate power supply arduino (9v battery), works perfect motors connected. working single power. When there is no motor connected, the relay clicks on and off at 1.5 second intervals as instructed by the code. as soon as i connect the motor to the relay, the arduino resets every time it sends a signal to click the relay over. If i connect more power consuming components to arduino, it gets reset. what is the cause of this observation?. If the power goes out, the battery supplies power to the arduino, when the power is back the battery gets charged again. just make sure your battery is big enough to bridge the longest supply outage you expect (or want to bridge).
