A UART link that works perfectly on a breadboard can fall apart the moment it meets a motor, a switching power supply, or a few meters of cable. This article explains why, and walks through the hardware and firmware needed to build a robust RS-485 link, using a vibration-test bench from my internship as a running example.

The miniaturisation of electronics applied to sensors

What constitutes an Arduino UNO? In this article, we will explore the electronic components of this famous board. Then, an overview about I2C and Arduino memory will be given.

Electrical devices are a social species. They shout, declare, tell, utter, verbalize, yakety-yak and yak all day - all night - their blabber to one another as part of a complex herd full of protocols and social hierarchy and all that, with not much of single sound. Now, imagine a world where all those devices where to fell silent overnight ; how would you recreate communication between them ?
