Today we made some sensors. I worked on making the 2 flame sensors while Sarah worked on the line sensor. We later found that putting the the phototransistor in backwards would give us a better range of readings.
This is the line sensor that Sarah made. We had many, many problems with this once we decided that the leads needed to be longer. We needed to extend the wires so it would reach the board, but we kept getting dead wires because the wires were very small. We pretty much took the whole thing apart and did it over again.
