Hello everyone,
I am working on an infrared LED array and just simply have exhausted ideas on how to fix this problem. This is my second time at this and still have not found out the answer. Here are my specs.
I have a 9 Volt battery independent source... The positive terminal is then connected to six (6) 940nm wavelength IR LED's then to six(6) one-hundred ohm (100Ω) resistors in parallel then connected to the negative terminal.
Here is my schematic:
(+)---->|-->|-->|-->|-->|-->|---|(17.5Ω)|----(Ground (-))
Here are the spec's to the IR LED's:
-forward voltage: (1.3 volts)
-forward current: (100mA)
I am using 18 gauge wire (AWG rated)
Here are the spec's to the resistors:
-100 ohms (Ω)
-1/2 watt power
-5% dissipation tolerance
I have used this website for the corect schematic/wiring diagram but do not know if this is wrong due to it possibly being only for regular LED's:
-http://led.linear1.org/led.wiz-
I am using my cell phone camera to test out the array and it picks up 940nm wavelength because I tested it on the Wii's IR sensor bar. (The project I am making this for is correlated to the Wii). Am I not getting the wiring right? (I also used a bread board).
PLEASE...if I'm doing this wrong correct me because I am a mechanical engineer and I dislike circuits to a great extent.
