Description Electronic circuit, Arduino, and a copper coil. here actually we are making a proximity sensor that detects the metal with a metal detector using Arduino. with the help of the RC circuit built in the Electronics part. now when we take this project near the metal it senses the metal near it due to the electromagnetic waves transmitted from the coil. hence with these electromagnetic waves, the circuit sends a signal to the Arduino. Arduino compares and processes the data and sends the instruction to the buzzer and the LED according to the code. the coil will generate the electromagnetic waves and when we take it near to the metal the electromagnetic waves get distorted. the circuit sends a signal to the Arduino. Arduino compares and processes the data and sends the instruction to the buzzer and the LED according to the code. the coil will generate the electromagnetic waves and when we take it near to the metal the electromagnetic waves get distorted. and Arduino gives the instruction according to all these data variations
