Shiny Lights!!!

So I've been a little slow to getting the right parts that I need, but last night I put in the order to sparkfun for some H-Bridges to control the internal motors with the arduino. The shipment should be coming in next week hopefully, untill then I've been messing around with some lighting for it.



The toy had some fake headlights that seemed to be the perfect size for some LEDs. I drilled out the pieces to accept the bulbs and am planing on wiring the LEDs in parallel. Each headlight holds 2 LEDs so I'll be powering 4 from the arduino, with the low voltage power supply I think parallel is the only way to go. I think it shouldn't take too much as far as resistors go, I plan to attach a 100 ohm resistor to each LED, further trial is needed to see if that will suffice. Below is a picture of it using two red LEDs, Untill the super bright white ones I ordered get here they will have to do. I plan to route wires from the LEDs through the little deck they stand on and then into the internals of the toy.



Untill the parts come I don't know if there is too much more to do, I also plan to measure the motors required voltage and current to plan their power source.
