When you push the button random values are saved to the EEPROM. To retrieve the values simply press the reset button on the Arduino and these same numbers are displayed (having been read from the EEPROM). When you hit the button you can also see write execution time. ...
Arduino For Loop: Easily repeat blocks of code saving processor memory and simplifying access to array data. How to Easily Avoid off by one errors.
Remember that the android app use’s Decimal numbers and the Arduino reads chars. So for example the android app receive a 48 and the Arduino will read like a ‘0’. See the ASCII Table for all the values: https://randomnerdtutorials.com/ascii-table/ Reply dui santoso December 24, 20...
A good tutorial about esp32 video camera here:https://randomnerdtutorials.com/esp32-cam-video-streaming-face-recognition-arduino-ide/ HASS geiger integration YouTube video:https://youtu.be/auRfZ5q2SrY This project will integrate a arduino geiger counter (one that supports serial logging of CPM)...
If you want to use I2C, you need to enable the I2C communication interface first.Raspberry Pi SPI PinsSPI stands for Serial Peripheral Interface, and it is a synchronous serial data protocol used by microcontrollers to communicate with one or more peripherals. This communication protocol allows ...
finding the maximum value in anintarray. Themax_indexfunction does the searching based on the index of the elements, whereas themax_valueis value-based. The goal is to calculate how much time they spend on finding the maximumintvalue in the1,000,000element array filled with random integers...
This is very critical in use-cases where sending very large data is necessary, without heap-allocation-error.The traditional function used to send Arduino String is void send(int code, const String& contentType = String(), const String& content = String());...
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 ...
In this tutorial we will learn how rotary encoder works and how to use it with Arduino. A rotary encoder is a type of position sensor which is used for...
Pins 7, 6, 5, 4 and 3 are connected to the digital pins of the display. It is not mandatory to know how the arduino communicates with display in order to use it; we will add appropriate library files to the arduino software which will take care of the communication between arduino and...
