Building a Real Time Clock (DS3231) with Arduino and a 1.8" color TFT display (ST7735) is very easy. All you need to do is to follow the steps we show in this video. The cost of the project is very low as well. You can build this project with around 10$. Impressive isn't it? That's the power of Arduino and open software.

The code of the project is very simple and it is described in the video. In the .zip file that I share, you can find both version of the code, with temperature in Degrees C and degrees F.
