I am working on a simple project of building a 7-segment display Digital Clock. I am using the counter CD4033 counter to count time. The clock pulse is provided by an 555 timer circuit that is set in astable mode to generate a pulse every minute.
The problem I am having is that my clock isn't precise enough. I tried larger capacitors in the timing circuit and it helped but that too wasn't enough. I think the timing is changing with room temperature and humidity. So, I am in search of clock pulses in alternative to the 555 timer. Any help will be greatly appreciated.
