prop 1 question

[Lindiur]

I'm not sure I'm in the section for this but I have a small prop. Consists of 8 LED lights and one 5v motor. All the LED's come on for .25 of a second, pause for 3 seconds the lights and motor turn on for 5 seconds. The trouble is I'm getting a power loss for some reason. When its just the LED's they turn on fine. When its just the moter it runs fine. When both are hooked up the lights barely turn on and the motor barely moves. Lights are on out1 and motor on out2. Do I need to seperate all the lights on to different outs or does it not matter. I'm obviously not an electronics wiz so any documentation or advice on the the reason for something like this would be awesome.

Thanks

I have this question for you and that is. What is amp draw of this motor and light, also how is this motor and light hooked up to the Prop-1?

The ULN on the Prop-1 can only handle 500mA and my thinking form your first post,that you are drawing many amps for the Prop-1 or your power supply isn't rated high enough to handle the load that you want to use.

BTW, a photo of your setup is always helpful and helps other forum members work out your problem.

Thanks for the response. I wish I could show a picture but I don't have any way to do that.  No camera and no phone hookup. I don't know the actual specs on the motor other than its a 5v motor.
I know i can power the motor with a 9v battery and the motor runs a little fast. As far as the prop setup i have the PIR set on Pin 6, the Positives for the LED's and the motor are on the v+; the LED's neg. are on the out2 and motor neg is on the out1. I hope that is correct. The code seems to work fine and everything turns on and off the way i need it to. And like I posted before they both work by themselves it just when they are together. I hope thats enough information.

The original plug to the motor is 4.5v and 1500mA

I would say you are drawing way too much current for the ULN to handle. You need to run that motor from a seperate power supply and use a relay connected to the Prop-1 to energize it.

I'm little confused here 

The original plug to the motor is 4.5v and 1500mA

Are you running the Prop-1 with 12V power supply? Is this motor connected to Out1 rated at 1500mA or is the power supply rated at 1500mA.

The prop 1 is on a 12v power supply the motor is was on a 5v 1500mA power supply. Can i hack the motor power supply and use it or will it damage the Prop 1

[bsnut]

I have this question for you. You're saying that the motor draws 1500mA, is this right and what is the true current of this motor? If this motor is above 300mA you can't run through ULN at all. Because it is too much current for the ULN as Jack and I are saying. What, you will need to do is hack motor controller or use an relay to handle the load of the motor. The only way you can run a motor through the ULN is if the current of the motor is below 200mA, since you are using the ULN for other things like solenoids. The best thing you can do is use a relay for this motor and any currents above 500mA.

You need to power that motor from a seperate power supply. Power the Prop-1 with your 12v power supply. Here's a simple diagram.

Thanks for all the help
