Machine to Machine communication, the communication between devices.

In this task, you have to connect a MIC on any development board (of your choice) and an LED on another development board. (both the development boards can be same)

• Use Bluetooth/WiFi, to establish communication between these two devices.

Your task is, if the microphone reads a value greater than 70(take any threshold value of your choice), then toggle the state of LED.

Deliverable:

• Sketch of both the devices with the name as a transmitter (for mic) and receiver (for LED)
• Constructed Circuit
• A small video of your task (not more than 30 seconds)

Please add proper comments.
