If you have a need to re-flash the ATmega16U2 chip with the stock firmware to restore the Arduino UNO back to normal, this is often done on the command line using avrdude or dfu-programmer, or with the Windows program Flip. The easier way for me is to just use the Arduino IDE. Not...
Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, and it is also very simple to build. All you need are a few basic parts, which are listed below. Arduino UNO R3 development board Two IR Sensors 16x2 LCD Display...
One huge advantage of the grblShield with the Arduino is the ability to use a regular old USB connection. Welcome to the 21stcentury. I know don’t fall out of your chairs. My harbor fright mini mill isn’t all that big. I really didn’t want the controller to be bigger than the m...
Basic Version: The Unity and Arduino code presented in this tutorial. Advanced Version: A complete library to fully integrate Unity and Arduino which users thread for an efficient two-ways asynchronous communication. This solution is discussed in the post titledAsynchronous Serial Communication. ...
Example code of how to use Arduino interrupts Below the example code of LED blinking in which the interrupt function is used to understand more clearly. const byte ledPin = 13; Led is attach on the board of input pin 13. const byte interruptPin = 2; ...
To have the capacitance measurements output to anLCD display, use the code below. Since the LCD uses pin 2, use pin 8 instead of pin 2 in the diagram above. Upload this code to the Arduino: #include <LiquidCrystal.h> LiquidCrystal lcd(12, 11, 5, 4, 3, 2); ...
fader.fadeTo(0, fadeDuration); } This code reviews the “Fade” example provided in the Arduino Examples folder. Installing the library If you zip the folder where all the library files are, you can redistribute that file to other developers. Arduino has an option to import external libraries...
Coding for an Arduino Keypad Now that we have the hardware ready to go, it is time to move on to the software side of things. Let’s put together the basic code for the keypad. Use the following code snippet to get the Keypad working. Upload it to the Arduino Uno and then open the...
