Hi, guys
I want to make some project for my homework about metal detector
I searched the schematic for metal detector on the internet and i found it.
Here is the original schematic
But, i want to add some LED for output, not just a buzzer. I already make a simulation in Proteus, is it true and how to check my schematic right or wrong?.BTW, when i run simulation, LED not on.I appreciate it if you comment
