Particle Code

Flash the following code to your particle after assembling the circuit shown above. This enables the particle to scan any Mifare RFID chip and displays the UID to console. It also sets up a reward system that incorporates the moisture sensor. Whenever the system detects that a plant has been watered i.e if the moisture level rises above a defined threshold, it publishes an event to the particle cloud which is then published as a tweet to a twitter account via IFTTT. The system can  also easily integrate functionality to request for water if enabled.
