Enseignes et afficheurs à LED

Pierre-Yves Rochat, Mamadou Lamine NDIAYE, Yves Tiecoura, and Alain Bertin TIEDEU

Comprendre le fonctionnement des enseignes et des afficheurs à LED, depuis les petites enseignes à motifs fixes jusqu'aux écrans géants à LED. Apprendre à les fabriquer et à les programmer les microcontrôleurs qui les pilotent.

Ce cours va vous permettre de comprendre comment fonctionnent les enseignes et les afficheurs à LED, depuis les montages les plus simples jusqu’aux des matrices de LED multicolores. Les concepts électroniques nécessaire vous seront donnés, ainsi qu’une introduction aux microcontrôleurs, tant du point de vue matériel que pour la programmation en C.

Chaque semaine, il vous sera possible de programmer des enseignes et afficheurs à distance et voir le résultat par vidéo.

Vous serez encouragés à fabriquer vos propres enseignes et afficheurs. Des techniques de réalisation de complexitié progressive vous seront proposées.
