The serial monitor is usually just used to display data from theArduinoon a computer monitor. But it can also be used as an input device that takes input from a user and sends it to the Arduino. This is useful for creating serial monitor based menus, calculators, and password logins, whe...
Some Arduino programs need to react to specific important events in a timely manner. One example of such an event includes detecting button presses. Ideally, the Arduino should react to the input as soon as possible. However, reading the digital pin that the button is connected to repeatedly ...
An Arduino is a development platform used by many development kits that operate using Atmel-based microcontrollers. Arduino doesn’t refer to a particular microcontroller, but rather a platform for microcontrollers. For example:The Arduino Uno used in this tutorial is a kit that has an AtmelATmega...
Inputs are used to get information about what is happening in the real world. For example, you can check if the button is pushed or not by using thedigitalRead()command. Or you can check the temperature in the room by connecting a temperature sensor and using theanalogRead()command. By c...
Arduino PulseIn:How to Measure input signal periods using an Arduino. There are two Pulse-In functions. Which one you should use for best accuracy? Find out why there two functions, why interrupts must be on for one and off for the other, and why your measurement might be inaccurate.Arduin...
microcontroller, which gives commands to the motor driver to drive the motor accordingly. In our project, the Arduino Uno is programmed to make the robot move forward, turn right or turn left and stop according to the input coming from the sensor. The output of the Arduino is fed to the ...
I am writing a computer program which utilizes input from some equipment which I seldom have availible in my office. In order to develop and test this program I am trying to use an Arduino board to simulate the communication from the actual equipment. To this effect I create datapackets on...
Arduino shiftIn is a purely software implementation of a serial input interface; The equivalent hardware interface is SPI (Although shiftIn() represents half of that interface i.e. the data input part).Many chips use a serial interface to reduce the number of physical pins, so instead of ...
