A Slight Modification To My Circuit Design

I had a problem with my previous circuit before. I decided to do a bit modification to it. I managed to make this one working =) .

5v Power Supply For Breadboard

I am thinking of using 5V AC to DC Power Adapter to provide power supply to my project. It will convert 110-240V AC power to 5V DC power. You can buy it online via lelong.com.my with only RM42.00.
