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....
eSpeak voice synthesizer on Raspberry Pi
You can turn your Raspberry Pi into an intelligent assistant by using a voice synthesizer like eSpeak. Thanks to this tutorial, you’ll be able to make your robot or application talk. Hardware Raspberry Pi 3 avec Raspberry Pi OS Internet connection and remote...
Using the SD module on the TFT shield with Arduino Mega
The TFT shield consists of a touch screen and a micro SD card module which is not compatible with the Arduino Mega board. We have seen in previous tutorials how to use the shield screen and its SD card module. We’ll now look at how to modify the SD library to...
Object recognition with Python
, , In this tutorial, we’ll look at how to perform object recognition with Python, using a neural network pre-trained with deep learning. We saw in a previors tutorial how to recognize simple shapes using computer vision. This method only works for certain...
Using a Tilt switch with Arduino
A tilt switch is used to detect the orientation or tilt of a system. It is often used to indicate if a system (such as an agricultural vehicle) is beyond its operating tilt range, or to detect the orientation of a display and thus change its layout. It does not...
Programming an ESP8266 via WiFi with the Arduino IDE (OTA)
, A very practical feature in the IoT field is the ability to program a connected microcontroller , such as an ESP8266, via Wifi. This technique is called Over-The-Air (OTA) Programming. Material NodeMCU ESP8266 USB A Male Cable Computer WiFi network Principle of...Products
