How to Make Led Driver for Laser or Led Diode

Visit my blogspot:http://macoprojects.blogspot.com/ or visit my channel:https://www.youtube.com/user/macobt Led driver made of two componets LM317 regulator and one resistor,value of resistor is calculated by formula R=1.25/current you get the resistance of resistor for example in video I use 1.5ohms 2resistor in parralel each one is 3 ohms.
