It is required to fix the project. On the prototype board, the controller performed its task, but when transferring to the printed circuit board, bugs appeared. The board was redone twice. In the last version, the device worked correctly, but only once. Now everything turns on but does not work as originally intended. The scheme is very simple, the vibration sensor triggers and turns on the siren through a transistor, and also with the help of a button, the sensor can be temporarily disabled.
It is necessary to find the cause and eliminate it (it is unclear what the problem is).
If the work is completed in the shortest time (3 days), the performer will receive an additional bonus.

13 2 days29 USDHello! I am ready to take on your order and help fix the problem in the project. I have experience working with controllers and debugging circuits, so I can figure out why the device is not functioning correctly after being transferred to the printed circuit board. I will study the schematic and code you provide. I will conduct an analysis — I will check how the vibration sensor interacts with the transistor and the siren, as well as the operation of the button. I will identify the cause of the bug. I will fix the malfunction and test the solution. If needed, I will explain what was wrong and how it was fixed.

Скорее всего, проблема связана с одной из следующих причин:
Пайка или контакты – стоит проверить соединения на печатной плате, особенно вокруг транзистора и кнопки. Лучше пройтись мультиметром и прозвонить дорожки.
Ошибки разводки или наводки – на макетной плате провода могли компенсировать какие-то недочеты схемы, а на печатной появились паразитные емкости или короткие замыкания. Нужно внимательно посмотреть заземление и разводку.
Неисправные компоненты – возможно, транзистор или датчик вибрации сгорел при пайке. Можно попробовать заменить их.
Проблемы с кодом (если есть микроконтроллер) – может, код не совсем корректно обрабатывает первый запуск или последующие срабатывания.
