Ok... I've run into a snafu here, and I'm getting a little worried now. I need this finished in about two more weekends so I'm kind of nervous... Anyway, I've got 6 transistors hooked up , I'm using a 9V battery that I've regulated to 5V for all power. Everything is hooked up, the transistors are all getting power to the center pin (That's the one that takes a little current... I'm not sure if it's B, C, or E...) and it's on breadboard, but I only have two IR LEDs. So everything's hooked up, it's just that only two LEDs are actually attached. This works fine, I get about a 40' range, but as soon as I add another LED, it stops working. The other LED I added is a visible white LED. So if I have one white and one IR, it works (~30' range), two IR, it works (~40' range), two IR and one white, they all flash, but the TV is unresponsive at any range.
I desperately need more than two LEDs in this circuit though because right now, I've got about a 10 degree margin of error... Can someone please help? Is it because I don't have the decoupling capacitors? Do I need to use more output pins? If so, can I just use two tiny85s? Thank you very much!
