Totally new to this. Tried googling and watching some youtube videos but can't seem to find anything that can related to my case. Do let me know if I'm doing something wrong.
I bought my module from Here
I used an apple adapter (output of 5v 1A) and a stripped an old usb cable and connected the red wire to the +IN and black(gnd) wire to the -IN and turned it on. Then relay then started making the switching on/off sounds and the LED(red in color) started flashing on and off constantly to the extent it is vibrating.
I panicked and turned it off.
Tried on my Arduino Uno but this time plugging into the 3.3v. No sounds seems ok, configured the ESP8266 using arduino IDE and connected to the IP address using EasyTCP and set up a switch function with HEX code:
A0 01 01 A2 and
A0 01 00 A1 respectively.
Toggled it and saw the TX signal on my Arduino Uno flash and got a response on my serial monitor (but gibberish symbols) but no response on the relay no LED.
Please assist, what am I doing wrong here?
And is stripping my wire a good idea? I heard that 5V and 1A might kill.
