20K-ohm resistor is pulled to 5V. This configuration causes the input to read HIGH when the switch is open, and LOW when it is closed. created 14 Mar 2012 by Scott Fitzgerald This example code is in the public domain. https://www.arduino.cc/en/Tutorial/BuiltInExamples/InputPullupSerial ...
As discussed above with the signals being in the form of either a "1" or a "0", we here employ an int datatype. We can name this variable as sensorValue, and fix it to correspond everything that's being read on digital pin 2. All these become achievable via a one line of code:...
I tried servo read block thinking that it might read PPM but it didn't work. I managed to write an Arduino code that reads it. Can someone guide me on how to make a S-Function block that reads PPM signal. Thank you in advance, Here is the Arduino code that reads PPM for 4...
In this project you’ll learn how to read from a digital I/O pin, using the digitalRead() function.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:...

In this Arduino basics I have explained the code implementation procedure wherein an external analogue signal is fed to the Arduino analogue input and translated or converted into a correspondingly proportionate digital readout. Here we employ a variable resistance in the form of a pot as the anal...
How to use an Arduino to read the callipers (using very few extra components). Details of another protocol found to be in use on some callipers. Basic Arduino code is provided. To see more of my work please visitj44industries. Step 1: The Callipers ...
functions for Arduino, which work faster than the 'built-in' functions while remaining as easy to use and portable as the original ones. If you just want to try the new functions, feel free to go directly to "Using the code" section, otherwise, read on for some introdu...
