It’s time to make this project interesting: we’re going to test out communication between an Arduino board and a piece of fruit. We had one lecture class on this process, so we talked to the teacher about how to do this. She drew a simple diagram, and then directed us to look at the CapSense tutorial.
The capacitiveSensor library turns two or more Arduino pins into a capacitive sensor, which can sense the electrical capacitance of the human body. All the sensor setup requires is a medium to high value resistor and a piece of wire and a small (to large) piece of aluminum foil on the end. At its most sensitive, the sensor will start to sense a hand or body inches away from the sensor.
We actually got this part working fairly quickly, testing with just one grape, then four, then all nine. This was rather quick. The next part can’t be too bad, right?
The Grapes of Wrath.
Next: Polishing and the Fruit Hero program
