...Smart LED APA102. 1. изменить порядок в массиве для клавиатуры, а лучше для LED, тк цифра ноль на панели стоит не перед 1, а после 9, между R и #. 2. Яркость у нажатых цифр пусть постоянно зеленая - сейчас плавно меняется. 3. # пусть сразу тухнет после нажатия, а не ждет 3 секунды и пусть загорается синим. 4. добавить звук нажатия кнопок 5. Добавить две функции для подсветки R (rfid reader) - при разрешенном номере R загорится голубым, если не разрешен то красным. распознование происходит в стороннем скрипте, который вызвает функции записи красного или голубого цвета в LED R. Цвет горит две секунды, потом опять белым как остальные. Клавиатура выглядит так: 1 2 3 4 5 6 6 7 9 R 0 # R k S R -reader - без датчика нажатия. два светодиода: 10 и 13. k -кон...

Срочно нужен человек, знающий и умеющий программировать arduino. Нужно с помощью arduino получить из станка 3 показателя: 1. определить начало и конец смены работника (с помощью индивидуальных RFID карточек); 2. знать сколько времени станок был в работе, а сколько в простое за смену; 3. среднюю скорость вращения вала за смену. Эти показатели записать в текстовом, табличном виде в сетевую папку на компьютере. Кому интересно - обращайтесь, дам четкое ТЗ, и обсудим сроки выполнения и оплату. В дальнейшем будет много работы на эту тему. В приоритете специалисты в Киеве.

We want to use all 144 bytes on a NTAG213 NFC tag with an MFRC522 module connected to an ESP32 microcontroller. The current library for the MFRC522 module only allows a handful of addresses on the NTAG213 chip to be read/written. We need someone to update the library to allow us to use all of the addresses. This could possibly be done by changing the blockAddr parameter type from byte to uint16_t.
