Luminosity measurement with a photoresistor

Luminosity measurement with a photoresistor

A photoresistor is an electronic component that measures ambient light. This component is useful in some projects such as a solar panel light follower or home automation to create a smart lamp that only turns on when it is dark or to set up an alarm with a laser...
Read and write on a SD card with Arduino

Read and write on a SD card with Arduino

One of the weak spot of the Arduinois the memory space. When playing with data (saving measurement, reading or writing to a file, etc.), it is necessary to have lot of space available. You can easily add memory to the Arduino with a Secure Digital card or SD card....
Program your Raspberry Pi with C/C++

Program your Raspberry Pi with C/C++

Ressources for Raspberry PI are generally written for Python but, as a micro computer, other languages can be used. If you know C/C++ ( If you come from the Arduino world, for instance) and don’t want to bother learning another computing language, it is possible...
Command a serial controller Maestro with Raspberry Pi

Command a serial controller Maestro with Raspberry Pi

When dealing with several servomotors and an extra number of outputs is needed to operate your robot (to control Hexana, for instance), a practical solution is to use a serial controller such as the Mini Maestro from Pololu. Prerequisite: Programming on Raspberry Pi,...
Control a DC Motor with Raspberry Pi

Control a DC Motor with Raspberry Pi

One of the main objectives in robotics is to make things move on their own. To give motion to a robot, electrical motors are oftenly used such as direct current (DC) motors especially for mobile robots. In this tutorial, we will see how to control such a motor using...
