While modding the Asus WL-520GU router into a wifi radio it’s time to bring out the breadboard. Interested in the project? Look here at Mighty Ohm.
After flashing the Atmega168 with the usbTiny the first phase would be to see if I can get some text on the display. I found a helpfull comment on the Mighty Ohm forums that, without actually attaching the breadboard to the asus 520, there will be text visible on the 16×2 lcd display.
Power is supplied through the usbTiny 6-pin ISP that is still hooked up since flashing the microcontroller.
After a first scare of seeing nothing I realise that the potmeter just might need a little turn. That was it! Text appeared on the display without further connections.
Note: this is the intial schematic on the breadboard. The final schematic of the project has more functionality and a few more components.
