First time arduino attempt. 4 switch inputs controlling 8 LED outputs
Micheal well easy solution is to use arduino nano as its bread board friendly and easy as it comes with the arduino IDE installed, well if size is what you are looking for then digispark attiny 85 can also do the task and its size is almost equal to a coin but for that youll need to install it in the arduino IDE which is a bit difficult.
