The return function in Arduino can be used to return any data type, includingintegers,characters, andstrings. To return a value its data type must be declared inside the function declaration. For example, if an integer is need to be returned, you must declare the function as follows: intmy...
Arduino analogWrite() function writes analog value (PWM) to a pin. It requires 3 arguments, pin number, value (0 to 255) and an optional argument frequency.
How to Get an Arduino Micros() Function With 0.5us Precision: I love Arduino microcontroller programming, and I regularly use it in aerospace research, as well as in home projects. As I work on my many home projects, however, I frequently find myself n
Most touchscreens are well-calibrated right out of the box. However, the detected coordinates sometimes do not match the expected values, and calibration is required to ensure that user inputs are mapped accurately. This article explains how to design and include a calibration UI in an Arduin...
The Arduino delay function is an Extremely Useful function which you can use to get small delays. However, sometimes it's not the right function to use � there is another!
In this tutorial, we will be programming the Arduino based PLC:M-Duino 21+to activate and deactivate an output with this amazing open-source software! Latest Posts Requirements M-Duino industrial PLC > Power Supply > B-type cable to program the M-Duino PLC controller or an industrial control...
‘LOW’. HIGH turns the pin on and LOW turns it off. Therefore, to turn on pin 13, we need to write ‘HIGH’ to it as shown on line 4 using the ‘digitalWrite’ function. In the digital world, a binary value of1means HIGH or ON, and0means OFF or LOW. However, for Arduino ...
If you write “34”, then you’ll have the String “34” in str. The data will be converted and read as an Arduino String object. And if you remember, we had set a Serial timeout in the setup() function. In this example the timeout is 10 ms, so the readString() function will...
Arduino int to string: How to convert an integer to a string. Find out the standard form and Learn how to code it yourself. Also find the one subtle error you missed.
The second function is the loop function which runs in a loop when we power the Arduino board. We can write our code in this function which will run in a loop. The programming language of Arduino is not completely similar to C++; there are many functions of C++ which we cannot use in...
