Building an an Arduino real time clock with a 1.8″ color TFT display (ST7735) is very easy. The project displays the current date and time along with the temperature. It also displays then minimum and maximum temperature. 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 parts needed are these:

Parts Needed in order to build an Arduino real time clock:

1. Arduino Uno:

2. DS3231 RTC module:

3. 1.8″ Color TFT:

4. Small Breadboard:

5. Wires:

Code of the project

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.
