This is my version on PCB of 20x4 lcd game of life. I did not write the code only made an Eagle PCB for it.
Step 1: An Error on the Schematic
I followed the schematic provided on the site only to realise the Backlight LEDs where inverted. Anyway for the type of LCD I had whigh is JHD 204A.
First I made cicuit on breadboard
Step 2: The PCB
I won't explain in details the making of a circuit PCB as I think most everbody got there own method.
The first PCB had the LED polarity inverted
Step 3: What You Will Need
I am including the Eagle PCB file
List of what you will need:
100uf electrolitic capacitor rated higher than 6.3 v
100 n ceramic capacitor
a tact switch
1 10k potentiometre
1 10k resistor 1/4w
1 10 Ohm resistor 1/4 w
an 20x4 LCD. verify the datasheet
16 pin female header
16 pin male header
Of course a way to program the tiny
This is a video from a IPhone
I hope that was somewhat interesting!
