Luckily for me, I’ve always had my wiring written in the top of all of my Arduino code.
Printer (GND, RX = 3, TX = 4)
RFID (VCC to 5V, /ENABLE to 5, SOUT to 6, GND)
Parallel Button LEDs (pin 1)
Speaker (pin 2 -> Small Cap -> Speaker -> Large Cap -> GND)
Button (A0, A1, A2, A3, A4, A5)
LCD LiquidCrystal display with:
LCD 4 (RS) to arudino pin 12
LCD 5 (R/W) to ground
LCD 6 (E) to arudino pin 11
d4, d5, d6, d7 on arduino pins 7, 8, 9, 10
I also included links to the tutorials in my code, just to make sure. Especially for the HD44780 LCD.
I planned out my perfboard, getting Creatron’s custom one. The white PCB connections on top are great for colouring with a red or blue sharpie.
Had to drill a couple holes to be bigger for the PCB fuse holders.
Those white mounts are great to work with. I had the metal terminals put in wrong, but I found out that I could just solder my wire straight to the terminal and put them in properly, they stay very well. All other ones were headers and hot glued to guarantee they won’t move.
I got some pens and used them to hold my boards off the metal box I’m using, which was my old ATX power supply that died right before my user test. Reusing things is great!
The components are to be powered then a 5V and ground wire will be attached to the 5V and ground pins on the Arduino.
Hope everything works out.
