So i just got my diode from kendall @ hightechdealz.com And i built a ddl driver for it. My question is, when i measure the voltage on my battery it is 7.7V, but when i connect it to my driver the output to the diode measures 7.2V. I dont know why this happens and nothing is shorted out. Also i...

i just bought this variable resistor(pot) and i am going to add it to my driver. can you tell me which two pins connect? and i also bought an lm317t regulator and want to know where the pins go! you can use paint to mark the pins! any help welcomed! thanks

Okay. so im going to an elecronic-parts store tomorrow and i have a list of things im going to buy for a driver. 100ohm variable resistor(pot) LM317T regulator 2X 10ohm resistor 1N4001 diode l.e.d(for testing) battery clip Switch i have the circuit board and soldering iron. do you have...
