Я новенький на форуме и вообще на ардуино новичок так что сразу извиняюсь если выбрал не тот раздел. Я не давно заказал набор на алиэкспресс и я собрал машинку которая объезжает препятствия с помощью ультразвукового датчика HC-SR04 следовал инструкции но когда загружаю код из инструкции машинка не едет а просто крутит датчиком когда приподносишь к нему что нибудь но когда отключаю свою конструкцию от компьютера то эта машинка ничего не делает. Прошу помочь.
