Bill of materials

Things I might need:

1. Solder
   • For soldering components to stripboard
2. Copper Stripboard
3. 5V water pump
   • For dispensing water to the plants
4. Transistors
   • To be used as a switch, allows the UNO output to be used as a signal, instead of directly driving the waterpump
   • Maybe rated for 0.2A? Depends on water pump supplied
5. Diodes
   • For freewheeling diode in water pump circuit, to prevent reverse EMF from damaging the water pump
6. Acrylic for engraving
7. Push Buttons
   • Inputs for activating the system, manual watering etc
8. LEDs
   • Individual Colored LEDS for what state the system is in, for instance on or off.
   • RGB LED
9. Resistors
   • 1kΩ, for LEDs
10. DHT 22
    • DHT22 accurate to 0.5°C whereas DHT11 is accurate to 2°C, huge difference
11. Buzzer or Speaker
    Not too sure on speaker programming but am pretty competent with buzzer tunes, use buzzer to play a tune or annoying pitch when water tank is low on water.
12. Wires
    • Could use some wires for jumper cables or dupont cables if exclusively working on breadboard
13. Breadboards
    • Maybe additional breadboards if not soldering? Breadboard exclusive project
14. 9V adapter
15. Dupont Cables
    • Female to Male Cables, for interfacing boards with Arduino Ports
16. Breadboard headers
    • For female to male dupont cables interfacing with Arduino ports
