Купил детям Keyestudio 4WD BT Multi-purpose Car V2.0
Собрал. Ардуино установил, библиотеки.
Но при подключению к компьютеру в мониторе вижу один и тот же код FFFFFFFF на какую бы кнопку не нажимал. И с одного и с другого пульта.
Помогите пожалуйста разобраться в чем дело. Новичок в Ардуино, да и вообще в программировании.
