Oogbewegingsopsporing met infrarooi sensor: 5 stappe

2025 Outeur: John Day | [email protected]. Laas verander: 2025-01-23 12:53

Ek het 'n infrarooi sensor gebruik om oogbewegings te sien en die LED te beheer.

Ek het oogballe gemaak met LED Tape NeoPixel.

Stap 1: Grondwet

Ek het twee sensors QTR - 1A gebruik vir oogopsporing. Sensing met Arduino en die beheer van die LED.

komponente

• SparkFun Arduino Pro Mini 328 - 5V/16MHz
• Adafruit LiIon/LiPoly-rugsak-byvoeging vir Pro Trinket/ItsyBitsy
• LiPo battery
• NeoPixel strook
• QTR-1A Weerkaatsensor

Stap 2: NeoPixel LED -oogbal

NeoPixel LED -band word gebruik. LED is 68 eenhede.

LED is met dubbelzijdige band en bedraad aan die bak vasgemaak.

Stap 3: Sensoreenheid

Ek het twee sensors QTR - 1A gebruik vir oogopsporing. QTR - 1A word op 'n plastiekvel op 'n afstand van ongeveer die wydte van die oog geplaas.

Die sensorgedeelte en die mikrobeheerderdeel is met 'n klem op die bril vasgemaak.

Stap 4: Arduino -kode

As die iris een sensor nader, neem die weerkaatsende lig af en neem die sensorwaarde toe. Omgekeerd, as die iris wegbeweeg, neem die weerkaatste lig toe en neem die sensorwaarde van die fotoreflektor af.

Die regter- en linkerbeweging van die pupil van die LED -oogbal voel die toename en afname van een sensorwaarde en beheer dit. As dit knip, verminder beide sensorwaardes, dus as die twee sensorwaardes gelyktydig afneem, val die ooglede van die LED -oogbal af.

Ek het die volgende biblioteek gebruik.

• QTRsensors:
• Adafruit_NeoPixel:

Stap 5: Bediening

Ontdek die linker- en regterbeweging en knip van die leerling met die sensor, en beheer die oogbol -LED.
