Paper birthday cards are boring…
So let’s build an "Arduino LCD birthday card!"
Step #1: Next
- Here are the materials you need:
- Arduino, LCD Display, 10K Potentiometer, USB cable, some hook-up wires and a solderless breadboard.
Step #2: Next
- First we connect the 5V and the Ground to the rails of the breadboard.
- Then we add the potentiometer and connect it to 5V and Ground.
Step #3: Next
- Now we add the display and connect it to 5V (second pin) and Ground (first pin).
- We connect the third pin of the LCD to the "wiper" (middle pin) of the potentiometer.
Step #4: Next
- Now turn the backlight on! Connect the sixteenth pin to Ground and the fifteenth pin to 5V.
- Plug in the USB cable and you should see the backlight light up!
Step #5: Next
- Now it's time to connect the data pins! The list that follows is: Display Pin → Arduino Pin
- 4 → 12
- 5 → 11
- 6 → 10
- 7/8/9/10 = No connection
- 11 → 7
- 12 → 6
- 13 → 5 and 14 → 4
Step #6: Next
- Now it's time to program the Arduino! Start with the code in the picture at left.
- Now it's finished! Print a sweet frame, cut it out and put it over the LCD.
