I have started a project using a micro controller to control a LED display and I am having trouble using transistors to switch the LEDs, I have 5 LEDs in parallel being switched by one transistor and each LED is individually switched by another transistor.
I have given each LED its own resistor and the problem I am having is that when all LEDs are on each LED gets dimmer then if only one was on. I don't really understand why this is happening but I'm not 100% comfortable with transistors and I have probably done something stupid.
I have attached a image of how I have wired it up but with only two LEDs.
Any help would be greatly appreciated, Thanks.
