hai,
better u design with adjustable voltage regulators like LM317.vary the values of resistors and get the voltage whatever u want!
NOTE:VIN>(1.5 + Vout).

hai all ,
presently am design led matrix display system.i tried with 16*16 with ULN .its look brighter when a single row is powered while powering the 16 rows the current is not enough and LED lost its brightness .so i referred some topics they suggest to put a FET . i need a part number which...
hai all,
i referred some site to use RMS-Dc converter at the end of current sensor output. is it necessary to add RMS-DC-converters?
Analog:AD736,AD737 from analog devices
LTC1966 from linear
is anyone tried that type of converters.how was the accuracy(linearity)?

karthikeyan
hai ALL,
presently am designing power monitoring system project.
In that am using ACS756 IC(hall effect current sensor IC). it gives sinusoidal output corresponding to the load(normal -1.6 DC in multimeter)
when i trying to interface it with ADC of my controller, i try to catch...

when i trying to interface it with ADC of my controller, i try to catch the peak voltage of ADC for corresponding loads.
but the out put is not stable...
hai every one,
i need a suggestion reg: how to measure line current values from shunt transformer circuit which having zero cross detect output,am interfacing the shunt transformer output with PIC controller.

hai kee,
this is your main it called all ur functions one time.it run one time only
void main() {
TRISB=0;
Keypad_Init();
Lcd_Init();
Lcd_Cmd(_LCD_CLEAR);
Lcd_Cmd(_LCD_CURSOR_OFF);
UART1_Init(9600);
Delay_ms(100);
start();
}
do like this
void main()
{
TRISB=0;
Keypad_Init();
Lcd_Init()...
sorry now only am seeing your main,
write all ur function in this manner
main()
{
initlcd();
initkeypad();//dont init ur peripherals in side while (1)
while(1)
{
watch keypad()//whatever u have to do then if its goto that thanks function call ur...
hai samuel,
nice design ya,here some correction
1. Put 0.1 uf capacitor near by controller between vcc and vss.
2. key bounce capacitor in MCLR and switches will help u to get correct pulse form status.
3.see the current rate of stepper motor and selected driver. if...
hai kee,
call ur main function like this
main();
after displaying 'thanks',and avoid while(1);
in your code,in some other cases it ll bug ur software.

karthikeyan
hey
it ll surely reply
1.check ur PC comport first,set ur controller baudrate with modems default firmware baud rate.
2.if it is a evaluation board it will work with straight cable RS232(DB9).
3.if it is ur own design check status pin whether its turned on or not because if u type anything when...
hai,
first check which mode ur phone is in default.with this following AT coomand
AT+CMGF?
if its 0 -->PDU mode
1--->text mode
ya it can be modified via like
AT+CMGF=1
text mode is the best method.
regards,
karthikeyan
hai cam,
ya i tried with 10uf capacitor at the end of the opamp IC of power measuring unit .but still its not stabilized its still wobbling. i think some other method is there to measure from shunt transformer output.
can anyone suggest me a better solution in this?
regards...
