Servo

I've got two sets of phototransistors and infrared emitters put together to make two IR distance sensors. They are both connected in the same way, both powered by my Arduino Uno, both with the same resistor, etc. But when I check the values I'm getting from them, one of them ranges from about 980 - 1010, with the higher value closest to the sensor. The other, however, goes from about 350 - 570, with the higher value the furthest from the sensor.

hello everyone.

I am working on a robotic arm mounted on an autonomous robot. I am done with the line following part. and It tracks the line pretty well. controlled 2 DC geared motors via fastPWM from atmega16 using motor driver l298, used LDRs and LM324 comparators for the line following. all the programming is done in avr studio 4 and used ponyprog to burn the code in atmega 16.

Problem:

Okay, I'm thinking the title probably isn't very descriptive but it's late and it's the best I can do. Basically, I've written a program in C# (I shall unveil this on here in a few days) that ouputs a value between 0 and 180 based on certain conditions. I want to be able to take this value and print it over the serial and read it at the Arduino end as an integer, so i can just have myServo.write(int).

At the moment, in C# I'm using sp.Write(int.ToString()); but I can use the same command to write a byte array and a char array.

I'll start off admitting that I'm a complete novice at robot building, so pardon me for what is probably stupid questions. I have bought an arduino with the intention of building a robot and have an idea of doing so mainly with servos, and I know that I can probably run them off the arduino without any problems helped by the arduino servo library, but can I just plug them in directly to the arduino or do I need a resistor in between or something? And question 2 How do I make my robot controllable via R/C? How do I put those circuits(?) together?

   On my current project I am using the Picaxe 28x/40x project board and I don't know where to hook up servos on it.  I searched around on the internet a lot but couldn't find anything about where to hook them up.  Not even the board's manual said.  I don't know if I missed it or what but I can't believe that picaxe would just let you go find this out for yourself.  I even entered the code to center a servo and went around on the board and tried to find were it was.  I also remembered to put a 330 omh resistor on the signal line of the servo.  I

Im currently building a remote control snow plow, yes it sounds crazy, but very cool. Right now im trying to figure out a way to lift the plow up and down. I have an actuator from an electric wheelchair. my issue is how do i hook it up to the servo so it can be remote opperated! 

Thank you for your help!!

Has anyone tried giving a 5mS or 10mS (or lower freq - 40mS or 80mS) time period PWM signal to a hobby servo rated to work with a 20mS PWM siglan input...

What I am trying to ask.. Is there any way to give a higher (or lower like 25Hz) frequency PWM input signal to a servo...?

I dont have a servo with me right now or I would have tried it my self.. But Im guessing the servo jitters... If so why..?

It is working now, thanks to everyone who helped me out!!!

I am trying to make my servo work,but if I start my arduino, with code and servo attached, it just goes to one position and stays there twitching. Can someone help me?

second try

this hasn't happened but say if i pluged as many servos as i could in my board would they have enugh power ? would i need a second battery pack?, where would i atach it? and how would i stop it from destroying my microcontroller?

thanks

i have buyed unbranded servo.. my servo is not in center.. if i set it to 150, it turns to one side...that is to 180degree. so i can't rotate it on both side.. can anyone help me to sotout this problem...!

Hello. I understand that this is a very broad question, and I have been looking into options but am confused as people tend to start getting quite technical with their answers rather quickly.

I am very very new to robotics, and would like to learn how to control servo motors via a PC, as in how to rotate the motor to different degrees around its axis. Ideally I am after a way that can control many servos at once.

UPDATE:

New code works well, but the motor moves slowly.

UPDATE 2:

New power source plug in, code working = Nothing
