Problem Statement: To make a ring such that, when worn it lights up.

Components required:

  • 2 BC547 (NPN Transistor)
  • 270 Ohms resistor
  • 100K Ohms resistor
  • 2 1.5V Button Cell batteries
  • 3mm LED strip / 3 small LEDs from a LED strip in a circular fashion giving a ring like design

The circuit diagram is:

So, the point is that the touch probes get touched, when the ring is put on, thus lighting up the LED. When the ring is off the finger, the LED doesnt glow.
