Arduino Read Digital Input. In this video we use digitalread to read a digital input and control a digital output on an arduino. Digital i/o pins on the arduino uno board are the ones on the usb port side of the board, and they might also be marked as digital on the pins, like in my case:

Get hold of these fantastic little devices here: Here is how to do it in code. Read a switch, print the state out to the arduino serial monitor. The arduino pin number you want to read returns high or low example code sets pin 13 to the same value as pin 7, declared as an input. Let’s say we want to configure arduino’s pin number 2 to be an input pin. Digital pin 13 is harder to use as a digital input than the other digital pins because it has an led and resistor attached to it. Web how to use digitalread() function with arduino. In order to configure a digital io pin as an input, we need to use the pinmode() function. Web the arduino gpio (digital io) pins can be configured as digital input pins to be used for reading digital inputs (like push buttons, sensors, etc). Learn digitalread() example code, reference, definition.
Each does an 'digitalread' on the appropriate input. Get hold of these fantastic little devices here: The arduino pin number you want to read returns high or low example code sets pin 13 to the same value as pin 7, declared as an input. Web in the 'loop' function there are two 'if' statements. Each does an 'digitalread' on the appropriate input. Read a switch, print the state out to the arduino serial monitor. Connect the pushbutton between pin 2 and ground, without any resistor as reference to 5v thanks to the internal. Learn digitalread() example code, reference, definition. Digital i/o pins on the arduino uno board are the ones on the usb port side of the board, and they might also be marked as digital on the pins, like in my case: Web how to use digitalread() function with arduino. This example shows you how to monitor the state of a switch by establishing serial communication between your arduino and your computer over usb.
