An acceleration system (10) for a brushless DC motor (12) is disclosed having the functional capability of rapid acceleration through one or more mechanical resonance points with electronic commutation of the windings being controlled by pulses generated by sensing the position and rotational velocity of the rotor of the motor and further having the functional capability of synchronous ...
Circuit Diagram: We have used an Arduino Nano for controlling whole this Metal Detector Project. A LED and Buzzer are used as metal detection indicator. A Coil and capacitor is used for detection of metals. A signal diode is also used for reduce the voltage. And a resistor for limiting the current to the Arduino pin. Working Explanation:
Metal Detector circuit diagram. As shown, the circuit oscillates at around 230kHz. One may also experiment with the frequency by changing the value of C1. A Faraday shield may be added to reduce ground effect and capacitive coupling, and this is wired to 0V.
