Round 2 of Electrobuzz hit off with the 8 qualifying teams learning about the basics of a metal detector circuit. The teams had an option between using a breadboard and soldering their circuit, the latter winning them extra credits. The participants were guided through the building of the circuit board and the coiling of the inductor by the organizers. The device used the principle of variation of inductance to detect the metal.

The participants had fun learning and building their own metal detectors and are looking forward to putting them to use in Round 3 to be held on 5th October in AB5.
