Communication between two ESP32s via UDP
, The NodeMCU ESP32 is a small microcontroller with a WiFi chip. It is possible to establish communication between two ESP32s, when they use the same network. In this tutorial, we’ll look at an architecture with two NodeMCUs exchanging data via the UDP protocol....
Setting up a UDP server on Raspberry Pi
, When the Raspberry Pi is connected to the Wifi network, it can communicate with other devices on the network using the UDP protocol. This makes it possible to control the Raspberry Pi from another device or to manage other microcontrollers using UDP requests. It can...
UDP communication between Raspberry Pi and ESP32
In this tutorial, we’ll look at how to communicate between a Raspberry Pi and an ESP32 using the UDP protocol. When devices are connected to the same Wifi network, they can communicate very simply by exchanging data packets using the UDP protocol. As both the...
Stream video from a Raspberry Pi to a web browser
, , , In this tutorial, we’ll look at how to stream video from a PiCam on a Raspberry Pi to a web browser. When a camera is connected to a Raspberry Pi, it’s important to be able to access it from anywhere. To do this, you need to set up a server and send...
A quick look at the C pointer
, The C language pointer is a very powerful tool for carrying out certain tasks. It’s a concept you need to grasp if you want to improve your C skills. Some algorithms will be more complicated or even impossible to write without the use of pointers. Introduction...
Create your image bank with Python
, , To train a neural network in object detection and recognition, you need an image bank to work with. We’ll see how to download a large number of images from Google using Python. To train a neural network, you need a large amount of data. The more data, the...
Remote access to the Raspberry Pi with NoMachine
In this tutorial, we’ll look at how to access the Raspberry Pi desktop remotely using NoMachine. It can be very interesting to communicate with your Raspberry Pi microcomputer remotely, whether to avoid having to walk around with a screen, keyboard and mouse, or...
Communication between two ESP8266 with ESP-NOW
, In this tutorial, we’ll look at how to set up two ESP8266s for communication using the ESP-NOW protocol. The ESP8266 is a development board integrating Bluetooth and WiFi. It can therefore connect and exchange data with devices connected to the same network....
