Sensor Connection to Quarky

We are using 4 sensors in this project:

1. DHT sensors have 3 pins: GND, VCC, and Signal. You have to connect the following 3 pins to the Quarky Expansion Board:
   1. GND to Ground Pin of Quarky Expansion Board
   2. VCC to 3.3V or VCC Pin of Quarky Expansion Board
   3. Signal to the D3 (Digital Pin) of the Quarky Expansion Board
2. LDR sensors have 4 pins: GND, VCC, DO, and AO. You have to connect the following 3 pins to the Quarky Expansion Board:
   1. GND to Ground Pin of Quarky Expansion Board
   2. VCC to 3.3V or VCC Pin of Quarky Expansion Board
   3. AO to the A3 (Analog Pin) of the Quarky Expansion Board
3. The gas sensor has the following connections:
   1. GND Pin connected to GND of the Quarky Expansion Board.
   2. VCC Pin connected to VCC of the Quarky Expansion Board.
   3. AO (Signal Pin) connected to Analog Pin A1 of the Quarky Expansion Board
4. Moisture Sensor: The moisture sensor provides real-time moisture reading from the soil. The moisture sensor connections are as follows:
   1. GND Pin connected to GND of the Quarky Expansion Board.
   2. VCC Pin connected to VCC of the Quarky Expansion Board.
   3. AO (Signal Pin) connected to Analog Pin A2 of the Quarky Expansion Board
