Hi all,
Im pulling (whats left) of my hiar out trying to find a part. Basicly I need a low profile Pot with built in spst momentary switch... anyone know of a part number and source? thanks

Wow ...
Never heard of that !!! ... in 40 Years of electronics ...
your switch might be activated at a moment, but which ... Could you explain further what you want to do ???

Hi,
See these links.
Best regards,

Its for a "Knight Rider" project.. .specificaly the "Surveilance Mode" box. Basicly there is one switch... you push it in and it turns unit on or off. You rotate it and it will move the LED's in responce to the movement. I might just say heck with that function and just go with a push on push off. I think the other function was only used in one episode if that. The rest of the time it just sat there ramping the bargraph up and down. It would be nice if I could find it... lord knows It took an act of congress to get the duplicate bargraph display... But I got an exact replacement part... Im probably better off focusing on developing the rest of the dash for now.

Thanks a lot Joe !!!!!Quote:

Hi Keith,
The bloody theme is still around! Enjoy!

P.S. Before you click the above link, cover the PC keyboard with plastic wrap.
If your not commited to a POT, you could use an encoder with a switch to do essentially the same thing (but you would not have the "stops" that a POT has). I love to use these for input devices. One knob is all you need! However, if you have never used an encoder with a PIC there is a bit of learning curve to get them working well. Worth the effort, though (IMO), and lots of resources on the forum/net to learn from.
Here are some from Digi-Key. More options to choose from on other pages as well.

Ive concidered using an encoder but doesnt that mean I'll need more than one pin for the input? Right now my pin count is prety much maxed out
As far as using an 3914/5/6 display, they are only for 10segment LED's.
Furthermore, This 12segment display is over used in the dash, its just everywhere... one of the other applications Im working on is the fuel consumption displays which takes the Fuel level and an odometer pulse and computes MPG and distance left... which obviously would require more than a display driver. Plus with the PIC you get the bonus of little sound effects. :)
So while Im not opposed to an encoder I have no idea how they work... have always assumed they output a 4bit BCD number... As it stands now the only pin I have left for input is portA.5
Yes, for the Switch/Encoder combination you would need 3 Pins. 2 for the encoder (preferable on a pin with an interrupt on change feature) and one for the switch. There are different types of encoders, this probable being the most basic.Quote:

yeah, About as old as me. ;)Quote:

Hey bearpawz, are you building a movie prop car or just pimpim' someone's ride?
Youve done it again !!!!Quote:
