Andando em um ancinho. Arduino

Eu raramente faço algo "baixo nível". Meu dia útil aproximado consiste no desenvolvimento de aplicativos móveis para negócios e em diversas partes gerenciais. Claro, às vezes eu quero me distrair. Acontece que isso é raro e, provavelmente, portanto, proporciona um prazer especial. Desta vez, foi decidido se distrair com o Amperka. Tetra ”, destinado a crianças e com a ajuda dos quais você pode aprender os conceitos básicos de circuitos, os nomes de quaisquer sensores e tentar programar algo que funcione no mundo real, e não na tela do computador. Em geral, quando você é um homem barbudo adulto - em geral é.
