If It's Worth Doing, It's Worth OVERDOING

Summary by Krater

The creator builds an automated aquarium liquid doser controlled by an Arduino and a mobile-friendly web app. The device uses four peristaltic pumps driven by relays and an Arduino Uno Q to precisely inject four different chemicals into the water flow before it reaches the aquarium.

Answers: How do you build an automated Arduino-controlled aquarium liquid doser with peristaltic pumps and a web app?

• Arduino automation
• peristaltic pump dosing system
• aquarium liquid doser
• relay board wiring
• App Lab software
• 3D printed injector
• Formlabs Form 4 SLA printer
• resin 3D printing
• water flow injection
• breadboard prototyping components

What it concludes

• The 12V power supply buck converter successfully stepped down voltage to 5V to power the Arduino and relay board.
• The example code successfully triggered the relay module via the Arduino pins, clicking the connected pump on and off.
• The 3D printed injector printed successfully on the Form 4 SLA printer with working liquid injection barbs.
• The custom component breadboard grid made it easy to snap and hold the microcontroller, pumps, and relays in place temporarily.
• The automated schedule successfully triggered pump 3 and pump 4 to dose measured amounts of liquid into the system at the set time.
