hello ppl,
My final year project is to control servo motor, i am considering two different loading conditions in the means of two switches which is connected to the P1.0 and P1.1 of the micro controller. I am taking the output pulse via P0.0. I am using ULN 2003 to drive the MOSFET IRF 840 and I...
Hello ppl,
i am a newbie in KEIL, can anyone tell me how i can load the program into 89S52 using the KEIL software?
It would be of great help if ppl respond quickly
@Kabiru:
thanks a lot for ur reply, is there any relation u can provide me, whether duty cycle is inversely/directly proportional to the speed of the motor?
Hello ppl,
is there any relation between speed and duty cycle???
I am using a micro controller to drive a servo motor. can i get a relation that relates the pulses from the controller to the speed of the motor?
Delay in 89S52
@IanP:
Thanks a lot :)
@All:
Does 89S52 contain the header file delay.h, if so i can directly give what milli-second delay i want, am i right??
Relay Doubt
Can i directly connect the output of ULN 2003 to the GATE of the MOSFET....i intend to do the same operation that a relay does with the pulse, so can i use ULN 2003 as a driver to the MOSFET?? suggestions pls
Relay Doubt
@IanP: one small doubt, should i connect the output of the ATMEL 89S52 to the relay or to the gate of MOSFET?? because in the above cartoon the control circuitry is connected somewhere else. thats y this doubt
I meant what is exactly mentioned in the above cartoon, thanks a lot for...
Relay Doubt
@Ian p:
The pictures are so self-explanatory :) thanks a ton for ur help.
Can i connect the output of the relay to the MOSFET of a buck converter??
Relay Doubt
@IanP:
I need to switch off the motor and is way i had planned to use a relay. I just didn't know which pin of the relay should be considered as input and which as output because i didn't find the pin configuration anywhere. I have got a 5V relay with me which is Goodsky...
Hello ppl,
my final yr project is to control the servo motor using micro controller, i have planned to use a relay but i am not sure which one to use. I am using ULN 2003 to drive the relay which is driven by a +12V supply but the motor that we are using is +4.8V-+6V, so which relay rating...
