C Programming for Arduino

Overview of this book

Physical computing allows us to build interactive physical systems by using software & hardware in order to sense and respond to the real world. C Programming for Arduino will show you how to harness powerful capabilities like sensing, feedbacks, programming and even wiring and developing your own autonomous systems. C Programming for Arduino contains everything you need to directly start wiring and coding your own electronic project. You'll learn C and how to code several types of firmware for your Arduino, and then move on to design small typical systems to understand how handling buttons, leds, LCD, network modules and much more. After running through C/C++ for the Arduino, you'll learn how to control your software by using real buttons and distance sensors and even discover how you can use your Arduino with the Processing framework so that they work in unison. Advanced coverage includes using Wi-Fi networks and batteries to make your Arduino-based hardware more mobile and flexible without wires. If you want to learn how to build your own electronic devices with powerful open-source technology, then this book is for you.

Communicating easily with Max 6 – the [serial] object


As we already discussed in Chapter 6, Sensing the World – Feeling with Analog Inputs, the easiest way to exchange data between your computer running a Max 6 patch and your Arduino board is via the serial port. The USB connector of our Arduino boards includes the FTDI integrated circuit EEPROM FT-232 that converts the RS-232 plain old serial standard to USB.

We are going to use again our basic USB connection between Arduino and our computer in order to exchange data here.

The [serial] object

We have to remember the [serial] object's features. It provides a way to send and receive data from a serial port. To do this, there is a basic patch including basic blocks. We are going to improve it progressively all along this subchapter.

The [serial] object is like a buffer we have to poll as much as we need. If messages are sent from Arduino to the serial port of the computer, we have to ask the [serial] object to pop them out. We are going to do...
