Схема состоит из: ESP8266, IR-приемник, дисплей 1602 с I2C интерфейсом. Хочу передать сигнал, полученный с IR - приемника на экран. Ниже приведенный скетч рабочий, позволяет принять сигнал с IR-приемника, вывести его в монитор порта Arduino IDE. Но не получается вывести его на дисплей 1602. Хотя пробное сообщение выводится. Видимо нужно как-то преобразовать сигнал, полученный с IR-приемника, но у меня не получается. В скетче это последняя закомментированная строчка в void loop. Помогите вывести сигнал на экран 1602.

* Changed GPIO pin to the same as other examples.
