Arduino Based Aquarium Auto Lighting System

Intro: Arduino Based Aquarium Auto Lighting System

In this DIY guide I will show you how to make your own Arduino aquarium auto lighting system. In this project I decided to make my own PCB that is based on Arduino UNO microcontroller - Atmega328p. Bellow you will find the electronic schematic with PCB layout so you can easily produce it. The current time can be set for the first time (or when the coin batteryis low) via the serial monitor. You can change the "lighting change time" or led color from code.

Watch the video below:

Let's get started!

Step 1: What You Will Need - Hardware

Step 2: The Circuit at EasyEDA, the Free Online Circuit Design Platform

Click here to see and make any changes to the above circuit.

Step 3: The Code

Connect your circuit with TTL to USB module with 5 cables to the programming header.

The pins RX and TX must be cross-connected.

NOTE: If you are using the Arduino UNO board make sure to remove the ATmega328 IC from it first and connect the headers RX to RX and TX to TX pins of the board. The RS pin must be connected to Arduino UNO reset pin.

Download the code from here and open it with Arduino IDE. Inside you will also find the library file.

Changes that you can make:

  • Number of neopixels that you have at line 13
  • Fade effect time at line 32
  • Changing lighting color time and color at lines 59-71

Note: Function setColor(0,0,1); will turn off the led strip and setColor(255,255,255) will set -full brightness - white color.

Current time can be set from serial motior (check the video in the first page)

Step 4: JLCPCB - Make Your Own Circuit Boad From 2$!

Click here to produce your PCB board!
Use JLCPCB for $2 PCB Fabrication & 2-day Build Time, the quality is really good, check the below photo of our pcb board.

Step 5: 3D Parts

Print them with your 3d printer, use 4 screws and 4 spacers to assembly the box-case.

Step 6: Well Done!
