I checked the 12 volt doctor in which no bulb in the series was glowing. Then I checked the circuit. Then I checked the DC rail in which the diode was bad and the fuse was also bad. I replaced the diode and the fuse and it started working properly.

@@AssiDabi most welcome dear Yes, you can measure angles above 90° with Arduino using the MPU6050 sensor. This sensor gives you the option to calculate roll and pitch angles, which are measured between -180° and 180°. Also you change the code extension (float angle = atan2(ay, ax) * 180 / PI;) 🥰
