I required IC based solution for measureing the Impedance of the LI-ION cell, for this i have chosen the AD5934, But it measure the Impedance in range of 100ohms to 10 Mega ohms.Li-ION cells having very low Impedance.
Can I connect a series resister with cell for measuring the cell...

I have to convert the 0v to 5v signal to 0.8v to 3.6v using analog circuit.Input 0v means output should be 0.8V & Input 5v means output should be 3.6V.How to do the scaling with out using micro controller.

what are parameters to consider while choosing the GSM module
Hi
I have seen data sheet GSM modules.Some modules having TCP/IP stack & some modules not having TCP/IP stack.
Actually i am new to wire less technology.
Please suggest what are parameters I have to consider while choosing the...
Hi
GSM(MC37i) is the GSM module with out TCP/IP protocol.
My application is only find the position of the object & send the SMS to the user.For this application TCP/IP is required or
not .

Hi
I am doing vehicle tracking system.For this project iam planning to use GSM(MC37i) & GPS (ET318XC) Modules.
Can any body gives the information how to interface these modules with micro controller.

Re: MOSFET switching.
Hi
what is boost trap capacitor,why we need this circuit for High side MOSFET.
Can give some explanation or online materials regarding the boost trap.
Thank you.

Hi
I need some information regarding the Power MOSFET switching.
1.what is the difference between high side & Low side switching
2.when we have to use High side switching
3.when we have to use Low side switching

Solinide Feed back
Hay
I need feed back from the solenoids (24V, 300mA) whether they are switched ON/OFF, I am switching the solenoids using micro controller & IRF510
I kept a resister 1 ohm across the Source to ground and giving the voltage drop to the comparator (non inverting terminal of...
Re: I2C
Hi
PCF8574AP Port Expander is responding & it is giving ACK signal. Problam is with Pull up resisters (Vcc=3.3V), when I kept 10k pull up resisters device is not responding, I think bias current not sufficient for SCL &SDA Pins. When I kept 3.3K Resister devices is responding I think...
