This project was set up by a fan of sainsmart named Dieter. In this project, he has used the SaintSmart 1,8″ TFT.

Let’s check how did he make it.

New Project – Temperature Control (ST7735 TFT Display + Arduino

+ PT1000 )

Hi @ll,

I have started a new poject…….

A friend ask me to build him a temperature control unit for his home brew beer production. 🙂

This control unit should be able to hold the temperature of a fluid on a defined temperature level and control the heating of the fluid tank.

The heating element of the tank has a power of 1800W.

To control it, I will choose for this task a 20A relay.

My Setup:

SaintSmart 1,8″ TFT ( similar to the adafruit TFT) – useing the adafruit libraries (ST7735 and gfx)[click]
