Hi All,
I have a home made projector lift which I'm controlling with the Netduino. The control has 2 methods, infrared sensor and manual override. Each method will have 3 controls each (Up, Stop and Down). The lift actuator is driven by a relay shield
http://www.ebay.com....RK:MEBIDX:ITTheoutputs will be to solid state relays.
All the coding worked, cleaned up some bouncing with the manual switches and tested it with the actuator all works well.
The problem I have occurs when I try to control the screen, the receiver module for the screen has an input relay with inputs for Up/Down/Stop/Ground, so I was just going to wire it into the Netduino... but couldn't get it working, turns out they are expecting 5v (4.7v after measuring with the multi meter), what would I need to do to get the the Netduino working with the 5v relay... transistors? I'm not very knowledgeable on electronics so clear steps would helpful...

In the mean time while waiting for that solution, I though I'd used the 2 spare relays on the relay shield to control Up and Down on the screen, it is controlling the screen but the output is bouncing all over the place and executing interrupts for different pins (seeing it via debug commands to console) - example the relay output is D5 but it's causing the interrupt to run for D1 and D2. Any ideas as to why the output would be bouncing so much and hitting other interrupts?
My preferred option is to to run the screen from the pins on the Netduino rather than via the relays.
Any assistance would be greatly appreciated.
I've included a diagram - the 2 diagrams are essentially the same, I've included the Netduino so you can see which pins are being used and then that translates over to the relay shield
Thanks again for the assistance....
