One way to return an array from a function in Arduino is by using static arrays. Although it’s not possible to directly return an array by value in C/C++, returning a pointer to a statically declared array is feasible. This pointer can be used to access the array elements outside the...
In this tutorial we will learn how to make an Arduino Robot Arm which can be wirelessly controlled and programmed using a custom-build Android application. I will show you the entire process of building it, starting from designing and 3D printing the robot parts, connecting the electronic compon...

Introduction: How to Make LEDs Flash to Music With an Arduino This is a guide to make an LED flashing circuit that "beats" to an mp3 file on your computer, which can add an awesome effect to any sound-related device, or even your room (if you extend the concept with LED drivers or ...
size: This denotes the number of elements the array can hold. It’s an integer value representing the size of the array. This size can be determined dynamically during runtime. Let’s look at a couple of examples to make this clearer: ...
To make it slightly more interesting, we can map some continuous controllers to change the colors on the fly. Custom Instance This visualizer is going to use an Arduino Uno, which doesn’t have native USB support. To get around this I’m going to use the Hairless MIDI to Serial Bridge ...
Arduino Strings have been getting bad press due to the extra memory they use to make copies and the memory fragmentation they can cause. These can eventually consume all the available memory and cause the micro to miss-behave and reboot. This tutorial will show you how to avoid these two me...
In this project i'm using an arduino leonardo to simulate a possible USB attack using HID (humain interface device). YouTube video:https://youtu.be/PsYTfWgX3eU Full turorial:https://www.instructables.com/id/Arduino-Keyboard-Exploit-Demo-HID-and-Prevention/ ...
In this tutorial we will learn how to build an Arduino Mecanum Wheels Robot which is capable of moving in any direction. The unique mobility of the robot...
You can now receive the Arduino data. The only step left is to convert it to the variable you want to work, in my case, a double. Serial receive final block diagram: Arduino setup - Send To send binary data from Arduino you have to convert your float to an array of bytes uint8_t...
