#GETTING INPUT FROM WIRE ARDUINO HOW TO#

In line 4, specify вЂњINPUTвЂќ in pinMode() to switch pin 7 used this time to the input mode. Create the following program and write it to Arduino: Here, letвЂ™s check the change when connected to the 5V power supply and GND using a jumper wire for pin 5. LetвЂ™s actually try digital input with Arduino. You can use these input values to control the operation via processing such as conditional branching after checking them. The program reads вЂњ0вЂќ as LOW and вЂњ1вЂќ as HIGH. The input is вЂњLOWвЂќ at 0V or вЂњHIGHвЂќ at 5V. The pin states can be checked by switching to the digital input mode programmatically. With Arduino Uno, you can assign any of the pins D0 to D13, originally used for digital output, as digital input.

This time we will describe how to implement digital input using a switch. For example, you may want to operate the motor when the digital input is HIGH or stop it when the input is LOW.ДЄctually, the state of the digital input pin is switched to 0V or 5V using an electronic component such as a switch. These input values can be used to control other electronic components. By doing this, you can check the voltage applied to the pin with input in two ways, вЂњLOWвЂќ and вЂњHIGHвЂќ. The digital output pin can be switched to the digital input. You can also use the output to check the electronic components.

The digital output enables you to control the LED and motor, switching the digital output pin between two states, HIGH (5V) and LOW (0V). In this article, you can learn how to use tact switch in your Arduino project and how it actually works. This article was translated to English, and was originally published for deviceplus.jp.
