digital potentiometer ic's are difficult to find here in Pakistan or you will have to import it, which takes time , which i dont have :). Can you name some commonly used digital potentiometers so i should have a look at local market?
I tried with stepper but running a stepper motor is a heck of job. Firstly finding a right sequence to rotate is difficult , then it draws too much current ( about 1 to 1.5 amperes) , thirdly stpper motor i tried with rotates with too much slow speed.
I haven't tried servo, will it be easy...
In one of my project i have to rotate potentiometer knob through microcontroller . I have to distribute the 360 degree rotation of knob in ten steps. Is their any other way without using servo or stepper motor ??
Hi all. I am getting a weird type of error.Its a simle code to count the interrupts in ten second. When i physically implement the circuit on bread board , its counting more low level signals ( grounding the pin 3.2) . Like if i ground it once it should count/display one but its displaying...
I urgently need keypad code in c for 8051 without using interrupts and not using port 3 because all of my interrupts are used. Actually i would have loved to write the whole code by myself but currently i have tons of other code to write and all the code on forums is using interrupts or port 3...
Sorry i didn't get you.

No i am talking about somoe way to program microcontroller.
I am making a calorimeter for a treadmill. The formula for calories burnt by a person includes:
1) Sex
2) Weight
3) Speed
4) Time of running
Can somebody help me to chalk out a way to do it with 8051 microcontroller. I mean how will input weight from user. How to count/record the time a...
I have a dc stepper motor with six wires. Two for dc input of 12 volts and other two A,B,C,D for stepping sequence. The motor step angle is 1.8 degree. I want to rotate it with 200 steps in one complete rotation(360 degree). Can some one devise/tell me the stepping sequence i should use. ?? I am...
I am a beginer in plcs. Mean i have just started learning basic ladder diagrams and implementing it on plcs in my university. So is plc virsus is a possibility? Do they exist? Share your knowledge.
I am making a excercise treadmill. I am using 8051 microcontroller. I need a way to make my 8051 remember the last speed selected. Try to give a simple solution!! . No rocket science :) Its just a treadmill so dont take it serious.
