Hello all,
Well, the short and skinny: i'm building a 1/24 scale trailer model, and have decided to put some tiny led's on it (and also a few micro motors that can be switched on and off). Like the title states, i'm still stuck in the tutorial stage of this, so figured I'd post this in the project forum as i'll likely need more assistance as this progresses.
I decided to start simple as i don't have very much electronics experience, and just hook up 1 LED with a switch. Picture of the schematic is attached. I soldered up the components to a radio shack board, everything seemed to work great. Switched it off, took a little nap, then came back out and the led was on. I flipped the switch and it got a little brighter. So now, the led stays on all the time, and the switch just varies the brightness. I tried rewiring the circuit (the battery and diode are both flipped upside down and the switch is moved between the two). This has the same affect, but the LED is a little less bright when on all the time.
Any ideas on what is wrong? Maybe i applied too much heat to the switch when soldering? Components in the wrong order? The circuit will (hopefully) eventually have about 20 or so lights in series and parallel configurations, and will be very difficult to work on once installed. Any suggestions for more robustness to the circuit?
Attached are pictures of the circuit with the switch on and off after i rewired it. (the relays and black wire are not hooked up to anything currently).
thanks in advance for the help
