I ended up with a couple of PIC microcontrollers, PIC16CR54C, PIC16F628A a single supply OP AMP MCP602 i/p and a Horn driver C101E , transformer, diodes, three digit LED display which can be used in some electronics experiments. http://amzn.to/2ifN3FD You can help support this channel by using the Amazon affiliate link above for any of you future Amazon purchases.
