cap sense key
Hi all,
I am using capacitor sensing technique for sensing user key press.
NE556 was connected in Astable mode and the capsense act as a capacitor in that. Hence the change in output frequency is monitored by a controller for detecting user key press.
But with this method, i...
Hi,
Thank you.
I applied your method in the "MUL" and "ADD" instructions of 8051 which i use.
Iam getting the result but its in hexadecimal form. Can i know how it could be converted to decimal form or BCD form?
Because need to give that to the seven segment display.
I couldnt find a...
Hi,
iam interested to know whether i could do floating point calculations in AT89S52 microcontroller.
If yes, could any one give me some example on how it could be done using Assembly language programming?
for eg: how could i do the following using Assembly language programming??

Hi,
I need to drive Solid State Relay(SSR) with the help of microcontroller port pins.
can any one tell me how could i do that so that it is safely driven?
the input to SSR can be (3 to 32)V with input current 1mA and SSR switches 110V dc / 2A.
Can i use a transistor connected to...
Hi,
Can any one clear me on the exact use of free wheel diodes in coil driving?
Iam not clear with the direction of reverse current flow. does the diode used to protect the transistor or the supply voltage from getting spoiled?
Please give some light on this.

Hi,
This really seems to be a nice piece of information.
I didnt get this when i searched for linux free version.
Ok. Can you give more details on this operating System.
What exactly does it mean by saying Linux Distribution??
Does it mean that it would support all softwares supported...
Hi,
I thought i could try to develop some projects at home and may sell it if it comes successful.
I dont know whether i could do this at home. So i thought of getting some information on this.
1) I would like to know whether i could use "windows XP home edition" which i have now for...
Hi,
Evaluation versions cant be used for commertial purposes.
Thats why i am looking for Opensource or freeware type that could be used for commertial porposes.

master clock design
Hi,
At present i am working on a project to develop a GPS based master clock.
I am searching for more information on the subjet and also for implementational ideas. I would be using a microcotroller for it.
So if i could get some advices, materials or useful...
Hi,
I would like to know if there are any PCB design software that is Open Source (free to use). I am on lookout for such thing for developing commertial applications.
Suggestions please.
