Automated light control
In this recipe, we will look at automated light control using M2M. We will work on a project that will turn a light source on or off, depending on the light intensity of the surrounding environment. Two ESP8266 boards will be used to accomplish this. One of them will have a light dependent resistor, and the other will have a relay connected to it.
Getting ready
You will need the following hardware components:
- ESP8266 board
- USB cable
- Light dependent resistor (LDR) (https://www.sparkfun.com/products/9088)
- 10 kΩ resistor
- Relay module (http://www.dx.com/p/arduino-5v-relay-module-blue-black-121354)
- Breadboard
- Jumper wires
Connect the analog input of the ESP8266 board to an LDR connected to a 10 kΩ resistor in a voltage divider circuit, ...
