Microcontroller interface and value

[bfaubion]

Hi All, I've been looking around to try and get a guage for how much i can charge to integrate a microcontroller with proximity sensor in a flash kiosk project. I recently started working with a microcontroller and an AS3 kiosk project came up, we are going to pitch the sensor to them.. but i have no clue how much this kind of work is worth. I have it working, so if a person steps in front of the sensor within a certain distance it goes to the welcome screen, and if they go away it goes back to a screen saver. I looked around online but havent been able to find much information or anyone that's doing this for clients.

you can use serial port and send data with xml socket to flash

That’s specific to the Arduino microcontroller, but the Flash side of things should be the same for most any serial interface.

Hmmm, both those replies seem fairly irrelevant to what you were asking.

I've got no experience in microcontroller pricing structures, but I'd do something along the lines of:

Figure out how much time you spent constructing purely the controller/electronics side of things.
Figure out how much you'd charge for the same amount of time building the Flash side of things.
Add/Subtract a little bit until it seems sensible. I imagine you've also done some extra Flash work to integrate this into your kiosk, which would also incurr an additional cost.
Possibly see if you can find out what low level electrical engineers get paid hourly, then multiply this by your time from step 1.

Really, you should charge whatever you'd be happy to accept. And given the filthy, capitalist society we live in, you'll probably want to double that and haggle with the client from there.
