Here is my 8 pin PIC12F clock. Still 70% of ROM is free. Will try to add more features. Will soon add a I2C temperature sensor and many more I2C devices and make a feature rich device.

Will try to make another clock with DS3231 which is a better RTC.

I think a Waveshare AD Keypad will be better. It needs one ADC pin to interface 4X4 keypad for RTC setting and LCD navigation. A MCP9808 will all do.
