In my current project, I am controlling Peltier Element Temperature which is current controlled load using Arduino. I am controlling Temperature of Peltier by applying PWM to H-bridge.
In addition to this, I have to change the polarity of Peltier Element. For this functionality, I am using two Electro Mechanical Relay. Once Relay starts switching it makes the controller Reset.
What could be the possible reason for this error? And How could I solve it?
