I am trying to invert the signal using BJT but it is not working.
Without the BJT , LED is always ON and only OFF when a magnet is brought close to the hall effect sensor. I am trying to invert the signal such that it is ON only when magnet is brought closed to the hall effect sensor.
Could anyone please point out my mistake why it is not working? Now when I bring the magnet closed to the hall effect sensor , it doesn't turn ON at all.
