Welcome to Circuits Gallery Let's Upgrade your Electronics knowledge with the latest and greatest CG tips and guides. The story of Circuit Gallery is quite a funny one. During our college years, we had to fix a ceiling fan. It was our first-hand experience of how wiring an electric device wrong would turn it into a total disaster.
Instead, it has a pair of opamps in series, with the output energising a capacitor and powering a relay via a MOSFET when it has reaches a threshold voltage. Refer to circuit 1. You could use the same circuit but ditch the MOSFET (Q1) and relay, and link the D5/C4/R11 connection to an Arduino digital input.

The C1 capacitor is a variable capacitor with a value of 365 pF, C2 is a 100pF silver mica capacitor, C3 is a 0.05 uF disc capacitor and the C4 is a 4.7 uF capacitor . The Q1 transistor can be RCA SK3011 npn transistor or equivalent type and all resist
The above circuit diagram is of a low-cost metal detector using a single BC548 transistor and an old radio. This is just a Colpitts oscillator working in the medium band frequency with a radio to the same frequency. First, the radio and the circuit are put close, then the radio is tuned so that there is no sound from the radio.
