DIY Auto Fertilizer
There were times when I completely forgot to fertilizer my planted aquarium. More so, if I were to go on vacation, I would need to find someone I trust to dose that tank. So, why not have a machine do it instead?! This project is very simplified as it only utilizes a single pump.

Arduino Uno R3
All Arduino Uno R3's are open source. This means that any company can create and sell their own version of the microcontroller. Basically, they're all the same more or less, but with different brand names attatched to it.
Arduino Uno R3 Kit
This comes with a lot of additional parts if you're interested in going further with projects. This is overkill for the auto fertilizer.
Tactile Button Kit
You need 6x6x8. However, it's cheaper overall to buy the full kit.
Mini Breadboard
MOSFET - RFP30N06LE
Flyback Diode - 1N4007
IMPORTANT!
Dupont Wires
Mainly need MF and MM Dupont wires. The shorter the wires, the better.
Alligator Clips
Used as a replacement if you don't have soldering material for the pump.
Peristaltic Pump - 12V
Need this exact model pump, as I modelled the case to fit this exact pump.
Tubing Connectors
In case you need some as the connectors that comes with the pump are a bit small. This link comes with 120 of them.
Standard Tubing
This is just standard tubing. Nothing special. You probably already have some lying around.
12V 1A Power Supply
Do NOT go over 12V, or you risk damaging the Arduino!!! Needs to be at least 12 volts!
10kΩ Resistor
This is for the tactile button.
