The coffee plantbot - A coffee machine that grow strawberries

This is a lil arduino program to turn a coffee machine into a device that takes care of plants

Installation

Materials:

  • A Cheap mositure sensor
  • LED lighting
  • I2C OLED 0.96'' screen
  • 3 Relays
  • Arduino board (I used nano)

Instalation:

Connect the relays to:

  • The water pump
  • The growing lights
  • And the moisture sensor

Code:

  • It uses Switch_lib to control relays and Adafruit library for the 0.96'' OLED ( You'll need to have it downloaded on the Arduino library manager. )

  • Adapt the PIN definition to your needs:

// ANALOG INPUTS  PIN DEFINITION//

int moisture_sensor = A2;

// DIGITAL INPUTS  PIN DEFINITION//

int lights_p = 11;  // Lights relay
int r1_p = 10;      // R1 relay
int r2_p = 9;       // R2 relay
int moisture_p = 8; // Hsensor relay
  • Conect the OLED screen to the I2C ports. In my Arduino nano were A4 and A5

First run:

Once all connected, during the setup the program will do some test as follow:

  • Turn on the Screen
  • Turn ON/OFF the lights
  • Turn ON/OFF the pump
  • Get first sensor read

If all of this goes well the program will start to work.
