In this video, Zahraa demonstrates how to use the digitalRead() function when coding a pushbutton and using serial monitor.
- [Narrator] Alright, so for coding…the push button I'm going to go ahead…and open one the examples provided by…the Arduino library.…So go ahead and go to File > Examples,…and then select Basics,…and finally DigitalReadSerial.…So this is the code for Pushbutton.…So I'm going to go ahead and save it as another file…because I'm going to make some changes.…So File > Save As, and then I'll just add…pin 12 to it, and then save it.…
So the code, it covers most of things…we've already went through before…so on line number 12 you can see…that there's integer pushButton…that's connected to pin two.…So we need to modify that to pin 12…which is according to our wiring connection.…Then in the void setup which is line 15 all the way…to line 20 we have a Serial.begin initializing…the communication between the Arduino board…and the computer.…And the pin mode for the push button that's connected…to pin 12 is input.…
Now in the void loop function in line 25…this is the only command or function…that we've never covered before.…So now in order to read an input from Arduino…
