Probably a common project and maybe already done for you, this project represent an adjustable digital clock, but also we can see the temperature and humidity of the room every minute. The clock can be adjusted using 3 push buttons: press P1 to enter in menu, P2 -> '+' and P3 -> '-' , for hours and minutes. I placed the modules in a such way because I will use jump wires, so the location of the modules on the pcb doesn't matter for me. I found the original project on internet, with rtc module and the lcd, I just added the dht11 sensor to it and made some modifications to the program.

Pay attention to the polarities.

You know what to do if you like this project. :)

Also, leave a message if you are interested in the program.
