Question on Wireless Key Fob and MOSFET Solenoid Control
Greetings! I purchased a 700-10016 Wireless Key Fob, with the intention of having it control a solenoid using a MOSFET as a relay.
My issue is that I can't get the it to actually trigger the solenoid - or maybe I can't get it to trigger it long enough for it to move?
I've included a picture of my breadboard; the solenoid is connected across the diode shown between the MOSFET and the power supply board. When I move the red jumper wire from VT on the receiver to VCC, the solenoid is engaged through the MOSFET. But none of the VT/D1/D2/D3/D4 pins seem to be effective at what I need.
I saw another comment - http://forums.parallax.com/discussion/comment/1185507/#Comment_1185507
- stating that perhaps the receiver board needs to be configured to latch the signal on? I would like the solenoid to engage when the button is pressed and disengage when it is let up. I think I might need the "signal inter-locking (Latch )" mode of operation noted in that comment.
So, first of all: does my wiring make sense? I haven't breadboarded anything in 25 years.
And second of all: Will I need to connect a couple jumper pads to make it work the way I'm intending?
Thanks in advance for anyone who can help!
