Hi,
I am newbie and I have been reading a tutorial on the 7805 voltage regulator. I have created a simple circuit to test whether I am grasping the concept or not. The thing that I really don't get is tying the grounds from both sides (9V and 5V) of the circuit together. I have attached a pdf with the circuit diagram (to which I have added a resistor and a led in my breadboard) and two different angled photos of the breadboard. The input voltage is 9V coming from the battery clip. I am just wondering if everything appears correct before I apply power. The capacitor on the input pin of the 7805 is 100 uF and on the output pin it is 10 uF.
Thank you very much for any help you can give me.
