|First draft of a working prototype|
- Arduino UNO
- 10K POT
- 2K Resistor
- Single strand hook-up wire
- USB Cable
- LCD Display 5 x 7 dots plus cursor, 5 x 8 dots or 5 x 11 dots, dot matrix LCD (TN and STN mode.)
- Break-away male header strip
One of the things you will need to plug the display into the breadboard is a 16 pin header strip. 40 position break away headers can be purchased for less than $1 each. I'd suggest you get 4 male and 4 female headers if you are ordering on-line. They are extremely useful in all type of projects and you'll find you use them up rather quickly.
If you do not already have a breadboard, you can purchase kits that include a breadboard and a selection of pre-cut jumper wires. A good starter breadboard is the half-sized breadboard from AdaFruit Industries in New York City. A good supply of jumpers can also be had.
The USB cable usually comes with the arduino development board while the resistor and the POT can be purchased from any electronics supply. Digi-key has a good selection of resistor kits.
Here is a wiring diagram of the basic circuit.
First you will need to solder a 16 pin male header to the display board. This will allow you to plug the display into the breadboard. The header pins look like this when you get them.
