Help with PCB (find the malfunction, defect)
I assembled a board based on Arduino, added a relay, and when trying to start it - there may have been a short circuit.
I need support, and if you are good at electronics - then I might offer you a few additional tasks - to improve this and several new boards.

Полярность диодов (на реле) не правильная. Надо катодом на питание, анодом на коллектор транзистора. Для поиска неисправностей для начала лучше их убрать
-
Доброго, якщо потрібно розробка плат звертайтесь )
-
В помилку Вам вже вказали це діоди , транзисторам мабуть стало погано , від такого ))
-
Також зверніть увагу на даташит , для AMS1117 по виходу бажано встановлювати
електролит або тантал на 22 мкф , для більш стабільною праці
