The idea with tis project is to make a remote to my camera. Nikon D3200. In my first test I used a ir-led remote but I think it disturbed the cameras ir-sensor. So I got the idea to use an old 433MHz remote instead.
It works fine but now I want to make a smaller version with an Attiny85.
Since I use two libs, one for the Nikon remote code and one for the 433MHz reciver I'm not sure I just can't adjust the ports for it to work in the Attiny.
I use a home made programmer shield for an arduino uno and a Chinese avrusb. They work nicely.
