SMART GARDENING SYSTEM 

A Smart Gardening system Project integrates technology and automation to monitor, manage, and optimize the growth of plants. It utilizes various sensors, and communication technologies to create an efficient and sustainable gardening environment  

Components –  

1. Arduino Uno X1: This is the brain of your Smart Gardening System. It will control all the other components. 

2. Soil Moisture Sensor X1: This is used to monitor the soil moisture. 

3. LED Matrix X1: used to indicate the moisture of the soil 

Connection – 

Soil Moisture Sensor (FC-28): 

• VCC: Connect to Arduino 5V pin 

• GND: Connect to Arduino GND pin 

• AO: Connect to Arduino analog pin A0 

LED Matrix 

• LED1: Connect to Arduino D13 

• LED2: Connect to Arduino D12 

• LED3: Connect to Arduino D11 

• LED4: Connect to Arduino D10 

• LED5: Connect to Arduino D9 

• LED6: Connect to Arduino D7 

• LED7: Connect to an Arduino D6 

• LED8: Connect to an Arduino D5 

• LED9: Connect to an Arduino D4
