Python Programming for Arduino

Summary

By introducing the Firmata library, we avoided writing any custom Arduino sketches in this chapter. We will continue this practice during the remaining part of this book and will only use or make custom sketches when required. In this chapter, you interacted with the Arduino board by making the LED blink, which is the easiest way to get started on a hardware project. Now it's time for your first project, where we are also going to make some more LEDs blink. One might ask the question that if we have already done it, then why do we need another project to make LEDs blink? Let's find out.
