I spent week 11 getting the diffuser to activate with the code run by my Arduino. It now activates when it a certain amount of recycling is added to the bin. I did this by using a reed relay my code to simulate shorting the switch and activating the diffuser. I also started making some design choices when considering how I want to present my final project on exhibition day. I want to work out the best way to put my device on display and show its full capabilities. I also need to consider what features I want to have implemented by exhibition day.
