In this practical tutorial you will require the following extra materials:
1. P89V51RD2 Microcontroller -1
2. 10uf Capacitor - 1
3. Tactical Switch - 1
4. 10k resistor - 1
5. Blue LED - 1
6. 33pf Capacitor - 2
7. 11.0592 Mhz Crystal Oscialltor - 1
some of you might be confused if you can use microcontroller other than P89V51RD2 . Yes you can use. The common one is AT89S52 but you then have to look out for the programmer in the same way.
