In the beginning, I posted a clock that used PIC16F84A
micro-controller. You can see it here. PIC16F84A is very old IC and it has very less functions. Therefore, today I post a developed version of
that clock. It used PIC16F88 micro-controller. PIC16F88 built in many features
such as large memory, internal oscillator, ADC and many more. In addition, we can use this IC for our future projects.

You can use big SSD or LEDs to build this but therefore you should add more transistors. Like this.

Here I used 4 switches to control the clock.
- SW1 – Edit / Enter
- SW2 – Up Sec / Min
- SW3 – Down Sec / Min
- SW4 – 12Hr / 24Hr
- SW5 – Reset
