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.

Making the Arduino talk to us


Imagine that you have followed carefully the Blink250ms project, everything is wired correctly, you double-checked that, and the code seems okay too, but it doesn't work.

Our LED isn't blinking at all. How to be sure that the loop() structure of your code is correctly running? We'll modify the code a bit in order to trace its steps.

Adding serial communication to Blink250ms

Here, in the following code, we'll add serial communication for the LED to blink every 250 ms:

  1. Open your previous code.

  2. Use Save As to create another project under the name TalkingAndBlink250ms.

    Note

    It is good practice to start from an already existing code, to save it under another name, and to modify it according to your needs.

  3. Modify the current code by adding all rows beginning with Serial as follows:

    /*
      TalkingAndBlink250ms Program
      Turns a LED connected to digital pin 8 on for 250ms, then off for 1s, infinitely.
      In both steps, the Arduino Board send data to the console of the IDE for...
