Arduino: Building exciting LED based projects and espionage devices

Summary

That was super cool, wasn't it? The synergy when Arduino, Processing, and touch sensors work together is enormous. We first played with the basics of Processing and understood how it communicates with Arduino. We wrote a simple Processing code that could directly control the Arduino. Then we created a simple tic-tac-toe program using the capacitive number pad as the input device, and using Processing as the processor to make the game tick. Finally, we created a complicated pattern-processing program that takes input from the capacitive touch pad, which we realized is really powerful. You have learnt a lot from this chapter and I hope this serves you well in your coding endeavors.

In the next chapter, we bid farewell to Processing and say ...
