Идея заключается в управлении питанием планшета по определенному алгоритму, также посылка команд управления (эмуляция нажатий кнопок клавиатуры) на планшет по средствам USB (Arduino видится планшету как HID клавиатура).
А проблема то в чем? Вроде ошибок нет.
Проблема, трудно мне дается написания скетча для реализации этой логики.
Тогда в "Ищу исполнителя" видимо надо :)
Вот что у меня получилось
В скетче управление андроид планшетом резистивными кнопками и управление питанием
