Completed shield to fit on the uno.

The next part of the workshop focused on using the attiny through simple programs.

To use the attiny, the first step was to install attiny support for arduino softeware.

The installation files can be found here – and here -

After copying the files in the folder, the software should give the option of Attiny 85/45/etc under boards.

After installing the support for attiny, the next step is to program the arduino uno to be used as an isp programmer.

Once this programme is uploaded, with the shield in place, the attiny 85 can be programmed.
