Digital Clock - Part 3

This is part of the Arduino-based Digital Clock series. This post is the third post in the series. For the previous post in this series, go to Part 2.

I took a little detour from the planned post. Previously I planned to add buttons to setup time without using computer. However the breadboard I used was already crowded. So this time I transferred the circuit to a bigger breadboard, without changing the Arduino sketch. Notable changes are:

  • I no longer used the breadboard power supply. This time I used a LM7805 as the power supply.
  • I reversed the male headers on the RTC module. Now I can plug it directly to the breadboard.
  • I tidied the rats’ nest wires from before. Now I cut the wires by myself instead of using premade ones.

The result is prettier compared to the previous post, I think.

IMHO this looks much tidier.

The result of circuit transfer.

The LCD display used many wires, so this part still look bad. However this is still better than the rats' nest that was the previous post.

This bunch of wires is still big though.

I routed the wires under the LCD display to make it less disturbing.

Now I have large vacant area under the LCD display. That’s where I will put the buttons next.

See you around, folks!
