Hi
I'm brand new to electronics and no idea what I'm doing
I'm thinking of making this circuit. The power supply is a USB cable, about 5V and about 500mA. Each diode (they're LEDs by the way) are 20mA and 3-3.5 V each. Will this circuit work or do I need any sort of resistors or anything? Also if I add in a variable resistor will that allow me to change the brightness of the LEDs?
Any help appreciated
