Remove a sudden pulse on pin d3 of nodemcu when powering it up I am using node mcu and a 2 channel relay connected to the motor via pin d3.
When I power on the circuit, it shoots a pulse to the relay and i think it will damage the motor.
Please suggest me how to stop that pulse from turning on the motor.
D3 is GPIO0, which is used as an active low input to signal the ESP8266 bootloader to expect programming after a reset.
Use a different pin.
