Trashcan and relay board

[zeenon]

The last thing I needed to add to my trashcan prop was the ability to turn a strobe on/off. I had a few of these laying around:

http://simplecircuitboards.com/Spec%20Sheets/TTL%20Relay%20Board%2010A-V2%20-%20Spec.pdf

So I hooked up 12V to it, made a two wire harness for the TTL in and added the code to the original prop-1 code below....and nothing!

I'm not sure what I did wrong here?

' -----[ Program Description ]---------------------------------------------
' This program will wait FOR contact switch or PIR to close then trigger the
' trashcan lid to open, pause, then trigger the prop to pop-up. After 20 secs
' the prop will lower and the lid will close.

' Prop-1 moded ULN pin 1 cut/P7 jumper OFF/P6 jumper ON/DWN
' Prop-1 P7
' Prop-1 P6 is trigger to start connected to WR
' Prop-1 P3
' Prop-1 P2
' Prop-1 P1
' Prop-1 P0
' Prop-1 OUT0/V+ is connected to 12V solenoid (Lid)
' Prop-1 OUT1/V+ is connected to 12V solenoid  (Prop)

Scratch that......I know what I did wrong. I had the TTL in of the relay board connected to W&R, instead of W&B.

I was going to suggest you look at your relay or something on the strobe.  Your program ran fine on my test Prop-1.

You should be using the white (signal) and black (ground) leads from the TTL pin. Make sure that you're very careful with the connections.

If you had one of these, it would be plug-and-play (and no external 12v supply required!)  ;)
