microcontroller with led

[ansh]

I need help, I am beginner , I want to learn something by doing some work on hardware  I bought some electronics lab tools and component

 I want to blink Led using microcontroller

microcontroller -p89v51rd2
breadboard
wires black, yellow
battery 9 v dc
Electrolytic Capacitors 1000 μF
diode 1n4007
Ceramic Capacitors 22 ρf
7805 regulator
LED
crystal oscillator


I have made some connection on breadboard how to know that my controller and programmer circuit is working correctly

so I used multimeter I measured supply voltage for microcontroller I got 3.95 vdc and I saw 3.65 vdc for programmer circuit

so I am wrong  or I am correct ?

Where it says "no link here" there should be a link. On a breadboards that I have all of those power pins are connected so it looks like your battery 9V is connected to 7805 input and output. If all is connected correctly you should measure 5V ant 7805 output.
I would first connect everything except power to the controller.
Then measure if supply voltage is correct, 5V. And if it is then connect controller to supply.
