I've tried to imitate the below diagram for my Raspberry Pi using GPIO 0, without a receiver.
The diagram seems to show a resistor going to ground, and an (emitter?) going to ground as well. I know nothing about electronics (as you can tell), but I wired it together using this diagram. [this is one I made from the above one...]
Is my wiring attempt ok?
EDIT: I ran a modified version, where I connected the base to the 10k resistor and then straight to GPIO 0, and the collector to ground, with the LEDs connected to 5v. The LEDs are now constantly lit.
SIDE-NOTE: Generally, I've been incredibly confused with the posts online with regards to the correct amps, voltage from the Pi — 3.3v, but don't know enough electronics to know if the LEDs will demand a certain current, or receive it regardless (which makes it hard for me to determine what the resistors are for).
The LEDs are 1.3v, 100mA, but the Pi is 3.3v and supposedly 60mA max per pin.
