🧙🏽 📊 🛢️ Maquiagem para cyber cinderela. Projeto de fim de semana do Arduino. Cílios led 🐷 😜 🚘

Pela primeira vez, os cílios de LED foram mostrados pelo designer Tien Pham no The Maker Faire em San Francisco. Isso foi há dois anos. Bem, e quase imediatamente na caverna do alibaba, os ladrões chineses começaram a distribuir análogos por 400 ou até 300 rublos.

Nas figuras, são duas placas de circuito impresso finas com doze LEDs conectados por cabos finos à placa de controle com uma bateria. Os cílios luminosos são presos com cola especial em cima de regular ou falso, e o controlador e a bateria ficam escondidos no cabelo. Tecnicamente, à primeira vista, nada complicado. Mas! Se você olhar atentamente para a placa dos cílios, existem 12 LEDs e apenas três fios no laço. Ao mesmo tempo, os LEDs não apenas acendem ou piscam, mas também funcionam como luzes de funcionamento. Eu me perguntei meio dia como eles fizeram isso. Revisou um monte de comerciais. E, em câmera lenta, descobriu-se que os LEDs exercem qualquer efeito em pares. Ou seja, a tarefa diminuiu imediatamente para controlar seis LEDs em três fios. Mas ainda assim, três! Seis em três! Mais uma vez - seis em três. E mais ... Então ele repetiu novamente e a resposta de alguma forma veio à tona. Aqui está - o número de todas as permutações dos três elementos é 6!

Acontece que o microcontrolador separou três sinais em um loop composto por três condutores: zero, um e terceiro estado. Temos seis combinações / permutações, o que significa que em cada uma das permutações um dos seis LEDs está aceso. Se eles estiverem incluídos neste esquema:

Por exemplo, acenda o LED D2. Em A-zero, em B - o terceiro estado, em C-unit. Apenas o LED D2 está aceso!

Agora em diante. Zero e um nas saídas do microcontrolador são fáceis. E o terceiro estado? Ainda mais fácil. Defina o modo de entrada. Agora a entrada de alta impedância, que não é puxada para zero ou unidade, é praticamente desconectada do circuito de controle.

Em seguida, o código, controlando dinamicamente as saídas do microcontrolador, acenda qualquer número de LEDs. Fazemos luzes de circulação, piscar, brilhar, extinguir no final.
Abaixo está o código para o Arduino com vários efeitos para dois cílios com seis grupos de LEDs cada.

E essa garota, Veronica, demonstra esses efeitos.

Provavelmente, para algumas pessoas, esse método de gerenciamento já é familiar e você já o está usando. Mas de qualquer maneira, realmente queria compartilhar. Os Arduins devem gostar!
