I am using a 5V Relay. But to my surprise I am witnessing that the Module just makes the Relay module high through the digitalWrite command. And then if I try to set the input to LOW via any write command then it doesn’t switches.
If at the first go, I use digitalWrite() function with LOW attribute then it does that but after that it doesn’t switches to HIGH even if I give 10 commands. Why is it so?
But it is not able to turn the relay off. Why is it so?? I also connected the relay with Arduino and in that case the Arduino seemlessly turned on and off the relay!! Can anyone help?
