Problems compiling

[m0nde]

I am no expert in Arduino and trying to build this clock for my son. I have built the hardware and he has printed all the clock pieces. When I compile the code for the nano I get this error. Can someone please help me get past this issue please?
Arduino: 1.8.13 (Windows 10), Board: "Arduino Nano, ATmega328P"

Error compiling for board Arduino Nano.

Hello, m0nde, you managed to solve your problem with the compilation errors. If so, how?

[Alex-Ender35]

Which libraries have you used? Or maybe you have made changes in the firmware code?

[m0nde]

Sorry no luck here kind regards Nigel

Dear Nigel, I am very sorry that you did not succeed. I was able to solve the problem 5 minutes ago. In the author's sketch, there are links to the necessary libraries. After installing them, everything worked. If you are still interested, try installing them. Sincerely, Alex.
