I found this great instructable that shows how to breadboard this same circuit, and this is based on it.
This is my first project that I've taken from breadboard to schematic to protoboard to functioning PCB, so I'm going to try and document some of the pain I went through along the way, as well as some things that helped, in hopes that your first end-to-end electronics design is a little easier.
Step 1: Supplies
- Decently-sized Breadboard (I used an 840-hole)
- Breadboard hookup wires (I prefer stiff hookups for on-board work and longer flexible ones for ISP hookup and long runs)
- Multimeter with conductivity testing mode (beep!) and DC voltage mode
- Soldering iron - I have a 50-watt that I love.
- An etching vessel - see PCB etching instructables.
- A drill and PCB drill bits (I used sizes 65 and 75). A mini drill press helps too.
- A hot glue gun (optional, but barely - the wire broke twice on me with very little force applied)
- An AVR ISP programmer (I built a USBTinyISP)
- Helping hands (optional)
- An ATtiny2313 (or 2313A, which is what I used - functionally equivalent)
- An HD44780 LCD with a single row of pins
- A 20-pin DIP socket
- A 7805 Voltage Regulator (you can definitely get away with a low-amperage one too, I just had these laying around)
- A 100uF capacitor
- A 10uF capacitor
- A 330-ohm resistor
- A 10K-ohm resistor
- A 1N4004 diode (other diodes will probably work fine too - make sure to read the datasheet though)
- A 5K linear potentiometer (or between a 1.5K and 2.5K resistor if you don't care about contrast adjustment - YMMV)
- A 9V wired connector - preferably one that doesn't suck (I have suck ones.)
- Breakable male header strip - you'll need 16 pins, but these usually come as 40-pin strips.
- Etchant - again, see etching instructables
- Solder, preferably very thin stuff. I'm using .015 diameter.
- PCB, single sided, whatever color you see fit.
- Hot glue sticks - awwww yeah
