555 metal detector

A metal detector utilizing the AVR Tiny13 microcontroller and a 555 timer IC to energize the coil, providing an output to the Tiny13 at pin 2 (CLK1). This circuit is designed to detect metals and magnets. The schematic includes a 555 timer configured in an astable mode, which determines the frequency of operation. The circuit can also be adjusted to work with high-brightness LEDs and includes various applications and configurations, such as a pulse induction metal detector.

This circuit operates by generating a frequency that is modulated based on the presence of metal or magnets. The 555 timer IC, specifically used in astable mode, creates a continuous square wave output. This output is then used to energize a coil, which generates a magnetic field. When a metallic object enters this field, it disrupts the oscillation, which is detected by the AVR Tiny13 microcontroller.

The design includes various components such as resistors, capacitors, and inductors that determine the frequency and sensitivity of the metal detection. The output from the 555 timer is fed into the microcontroller, where it can be processed to provide an indication of metal detection, often through an LED or a buzzer.

The circuit is designed to be simple and effective, requiring minimal components, making it suitable for hobbyists and educational purposes. It can also be adapted for more complex applications, such as integrating with other sensors or systems for enhanced functionality. This flexibility allows for the creation of a range of metal detection devices, from basic models to more advanced systems capable of distinguishing between different types of metals.

Overall, this metal detector circuit exemplifies the use of the 555 timer IC in practical applications, showcasing its versatility in electronic designs.Metal detector using avr tiny13. i m planning to use 555 ic to energize the coil and giving this output to tiny13 at pin2(clk1). i metal detector using 555 (9) dark sensor circuit diagram (8) 555 dark detector circuit (8) pir detector circuit diagram (7) metal detector circuit using 555 (7) 555 in a circuit note the circle on the chip to identify pin 1 This is METAL DETECTOR This circuit detects metal and also magnets.
