This project is a small automatic cooling system for home theater rack. It supports 2 temperature sensors for different zones in the rack and 2 12V PWM fans (standard for PC case cooling).
There is a power switch connector for a switch mounted on the casing (will be designed and 3D printed later). A reset button is provided mostly for reprogramming purpose. There are 4 buttons for setting up temp...
The PCB attaches to the back of the OP-320A unit, which is a cheap operator console panel you can get off aliexpress or ebay for about $50, you remove the PCB with the unit and attach this as a replacement to give arduino compatibility.
Wiring mostly copied from teensy++ and uno so something of a mix here, Uses a standard Arduino shield header but you will definitely need to adjust your sketch...
Aim : To design PIC16F877A based Temperature controller, LM35 as Temperature Sensor, A pot reference set point adjustment. LCD to display Current Temperature, Reference Temperature and status of the output.
Software : MPLAB IDE.
Code : Assembly language(under development...).
## Arduino drives I2C LCD Controller based on a LCD1602 module ##
## LCD Software Library Information ##
ALL the displays will use the IMPORTANT Library written by Francisco Malpartida.You can download the Library:
[the great Library ]
you must have the library installed correctly.
And Check the small backpack interface board on the back. These small boards on the back inter...
