Step 0Start with collecting all the parts
Arduino Breadboard Relay LCD ScreenLight
sensor
You should also have an LCD strip and a bunch of wires. The pH sensor is a non-essential bonus.

Step 1Wire up the Power and Ground lines
Power = Red = Vcc Ground = Black = GND
Connect port 2 and 3 to the breadboard,as indicated by the cyan and brown lines.These are the digital“data lines”.

Step 2Connect the light sensor to the data lines
Data = SDA = CyanClock = SCL = Brown

Step 3Connect the LCD to the data lines
Data = SDA = CyanClock = SCL = Brown

Step 4 (Bonus step)Connect the pH sensor
Signal = Orange
The signal from the pH sensor must beconnected to Arduinoport A0

Step 5Connect the temperature sensor
Signal = Green
The signal from the temp sensor must beconnected to Arduinoport A1
Plug one side of the resistorand one side of the temp sensorin the same column on the breadboard. The signal wire mustbe connected to the same column.The other end of the resistor is connected to ground and the otherend of the temp sensor to power.

Step 6Connect the LED strip to the relay
Digital signal = Purple12V Power = Banded Red = Vin (arduino)
Connect the LED stripground to GND porton the Arduino.And the LED stripVcc to the Relay

Power it upConnect the 12V adapter to the Arduino
Arduino power input jack
