Bulb and holder
Step 1: Connect the Wires to the Bulb Holder:
Cut wire into two pieces and Strip the ends.
Screw the wires to the bulb holder
Step 2: Connect the Bulb to Relay:
Connect the Wire from Mains to Common.
Connect the wire to the bulb in Normally open.
Step 3: Connecting Relay to NodeMCU:
Connect jumpers from Vcc of Relay to Vin of nodemcu, Ground to ground and input 1 to D4.
Step 4: Configuring Blynk:
Step 5: Adding NodeMCU to Boards:
NodeMCU board manager URL http://arduino.esp8266.com/stable/package_esp8266com_index.json
Step 6: Uploading the Code:
Step 7: Setting Up IFTTT:
WebHooks URL: http://184.108.40.206/Your Authentication token/update/D2?value=0
The pin number specified here is the GPIO pin of the NodeMCU and not the physical board number.
Once the action is triggered, A web request is made. This turns the Relay-ON.
Similarly a trigger can be made to turn off by using Value=1 and body ""
Step 8: Now We Are Done:
