hi i am designing 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 want to know that is it possible to generate squre wave using tiny13 so that i can remove 555 ic from my circuit.also how can i blink leds after detecting metal using SPI or any other method?
please reply imigiatly.
