In Arduino, we can initialize an array with a given size; after initializing an array, we can add or replace the values of the array using a function. If we want to initialize and create an array inside a function and then return it when the function is called, we have to use the ...
In this tutorial, you will learn how to use the AnalogRead function ofArduino. If you are working on a project, where you need to measure the analog voltage or analog sensor value which gives you output in the form of voltage, then you need to use ananalog to digital converterof Arduino...
Here you can find out how Arduino shiftIn works and how fast it is. The main use for the function to receive serial input from a parallel to serial chip e.g. 74HC165 (8 bits). This allows you to increase the number of inputs to the processor using only two processor pins (you can...
Here is the code defined in ServoEasing.h just for the Quadratic operation - you use these definitions as in the code above - to select a start/end operation:#define EASE_QUADRATIC_IN 0x01 #define EASE_QUADRATIC_OUT 0x41 #define EASE_QUADRATIC_IN_OUT 0x81 #define EASE_QUADRATIC_BOUNCING...
In this tutorial I will show you how I build an Arduino RC Airplane. Also, I will show you how to control it using a custom build Arduino RC transmitter...
The function starts by reading the touch point data and determining the touch strength. When the strength exceeds 555, the touched variable is set to true. If the code detects a touch input, the function checks whether the repeat button is visible. If it is hidden, the calibration is ...
Moreover, functions in C++ come with a return type, defining the type of object that the function will pass back to the calling code. You have the flexibility to define functions that don’t return any value, denoted by the void type. Alternatively, if your function serves a purpose, it...
Arduino based Line Follower Robot A Line Follower Robot (LFR) is one of the most popular Arduino robotics projects that teaches core concepts of automation and sensor integration. This step-by-step guide will show you how to build a professional-grade line follower robot using Arduino UNO, with...
The “float()” function converts the integer value to a floating-point number. Typecasting int to float in Arduino Typecasting in Arduino programming is another way of converting one data type to another. In Arduino, typecasting from int to float is done by placing the data type you want...
Working with this sort of alcohol sensor needs a preheat or stabilization period for the device to function correctly. If you look at the device's datasheet, you'll notice that it requires a 48-hour preheat period. Is this to say that it must be turned on for 48 hours before it may...
