How to make a Simple Adjustable Power Supply using LM317 Voltage Regulator

In this video I'm making a simple but very useful Power supply to power up your electronic equipment under the current rate of 500mA and 3-15V DC Voltage Range. The LM317 Voltage Regulator has been used as the major part for this project.

Parts, that you required for this;
