Finishing the electronics
Today I’ve finished building the electronics for my Arduino driven box joint jig. On top of the schematics shown in part 1 I also included a standalone ATMega328 chip instead of using my Arduino directly. I was inspired by this page and it turned out to be quite easy.
The ATMega328 chip (including crystal and capacitors) that I bought came with the Duemilanove boot loader installed, so I simply inserted the chip on my Arduino Uno board, chose the Arduino Duemilanove w/ATmega328 option under tools and uploaded my sketch to the chip.
All I need to do now is to build a new box joint jig and install the electronics… 🙂
