Step 7Lets Get Started
I recommend going about this project (unless youre experienced) in the following way:
First off, we'll set everything out on a prototyping board (breadboard). Start off with the power supply, check it works with a multimeter and perhaps pop in an LED+resistor to make sure. Then put in a programmed AVR, wire that up, connect up your power rails and try a "hello world" blinking light application.
After you know that your programmer works, you can test a basic remote control - where turning the AVR on fires a shot every so often (this also demos the interval timer function).
Next we'll add buttons.
Then we can get onto looking at the ADC, but for this we'll need the LCD. So before we play with triggers we need to solder and connect the screen to the micro and run some simple lcd routines to make sure they're all working (there is a good application for this provided by the gentleman who wrote the libarary i'm using*). The intervalometer will also be added in a menu system.
Once that's all set up on the board and the program is working, we can start copying it over to the stripboard. The IC's will be in sockets for easy removal and it's worth adding a 10-pin header so you can program the chip whilst it's on the board. But that's getting ahead of ourselves!
