As described under the 'Process' section we encountered challenges while figuring out how to measure the spice in the spoon. We first tried with an FSR which wasn't sensitive enough, and then decided to use a photocell instead. After using the photocell, we used feedback provided by our classmates to make them function correctly in any lighting.
We also had an issue while deciding how to detect whether the spoon was on the stand or not. We solved this by using a magnet under an FSR and on the spoon. When the two magnets attract, they put enough force on the FSR to obtain a substantial reading - We got this idea from the team that made the mailbox.
