PIC16F877A sub circuits

[eleceyes]

I do programming on PIC16F877A so it can output pulses with cycle specified to make the lamp on and off, I simulate and it runs as I wish.
Now I have to design that circuit with real devices, I know if I design it like what I draw in Proteus software, it will not run, what circuits that I need more to have it operate ?
Thank you !

You don't have any power supply connected to the PIC, you don't have any oscillator components, and you can't run lamps directly off a PIC pin.

Thanks for your quick reply.
So I have to connect PIC pin via a resistor before connect to LED (uhm ... not lamp)
Oscillator 4Mhz
About power supply circuit, that is one I am wondering, what it looks like, include which components ?
Thanks !

Check my tutorials for details of what are needed.

Hi,
Nigel meant the supply voltage to the PIC. You're using Proteus to do the simulation, so you don't need to do so. There is no Vdd and Vss for you too, as I know. For the rest, check his tutorial.

I saw it, thank you so much
