README
README.mdCe projet, réalisé dans le cadre du Semestre 6 à l'ENSEA (Année 2025-2026), consiste à développer un prototype de mesure de distance basé sur la technologie Time Of Flight (TOF). L'objectif est d'utiliser un capteur laser compact pour détecter des obstacles et commander une interface visuelle de retour.

Questions
How big is the Projet PCB?
It measures 54.5 × 59.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Projet use?
22 parts, built around the ATTINY841-SSU and LTS-6980HR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Projet KiCad files?
From the perryPyn/Telemeter repository on GitHub, at the commit this page was made from: the board is hardware/Projet/Projet.kicad_pcb and its schematic hardware/Projet/Projet.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Projet design in my own project?
Its repository states no licence, so its author keeps all rights: ask perryPyn before reusing the design.
