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...
Because in general, the Arduino UNO R3 doesn’t have sophisticated hardware support for floating-point operation. For that, I decided to keep a 10 cm spacing between two IR sensors. we can also make sure the spacing between the actual IR sensor should be bigger than the actual moving ...
Number of Arduino interrupts in different Arduino boards Different types of Arduino board have different numbers of interrupts pins e.g. Arduino UNO have two interrupt ports and Arduino Mega2560 have six interrupt ports named as INT1,INT0. On the software side create sleep mode for Arduino and ...
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...
my advice is to start with theArduino Serial Starter. It has a lot (I mean… a lot!) of components and it comes with some great instructions. If you have a little bit more experience, you might want to buy the components you need separately. In this case, theArduino Unois the “def...

Arduino UNO R3Specificationsays thatmaximum current per PIN is 40 mA. So we need some limiting resistors. To light a LED we need approximately 15 mA. Resistor value can becalculatedas: R = V / I, V = 5 volt I = 10..20 mA

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...
