Silmaliigutuse jälgimine infrapunaanduri abil: 5 sammu

2025 Autor: John Day | [email protected]. Viimati modifitseeritud: 2025-01-23 14:40

Silmaliigutuste tajumiseks ja LED -i juhtimiseks kasutasin infrapunaandurit.

Silmamunad tegin LED Tape NeoPixeliga.

1. samm: põhiseadus

Silmade jälgimiseks kasutasin kahte andurit QTR - 1A. Tundmine Arduino abil ja LED -i juhtimine.

komponendid

• SparkFun Arduino Pro Mini 328 - 5V/16MHz
• Adafruit LiIon/LiPoly seljakoti lisand Pro Trinket/ItsyBitsy jaoks
• LiPo aku
• NeoPixeli riba
• QTR-1A peegeldusandur

2. samm: NeoPixel LED silmapall

Kasutatakse NeoPixeli LED -linti. LED on 68 ühikut.

LED on kausi külge kinnitatud kahepoolse teibiga ja juhtmega.

3. samm: andur

Silmade jälgimiseks kasutasin kahte andurit QTR - 1A. QTR - 1A asetatakse plastlehele umbes silma laiuse kaugusel.

Anduriosa ja mikrokontrolleri osa kinnitati prillide külge vastavalt klambriga.

Samm: Arduino kood

Kui iiris läheneb ühele andurile, peegelduv valgus väheneb ja anduri väärtus suureneb. Seevastu iirise eemaldumisel suureneb peegelduv valgus ja väheneb fotoreflektori anduri väärtus.

LED -silmamuna pupilli parem- ja vasakpoolne liikumine tajub ühe anduri väärtuse suurenemist ja vähenemist ning kontrollib seda. Vilgutades vähenevad mõlemad anduri väärtused, nii et kui kaks anduri väärtust samaaegselt vähenevad, lähevad LED -silmamuna silmalaud alla.

Kasutasin järgmist raamatukogu.
