 I think your going to also need a tension sensor


well it seen right... but i u could tell me witch sensor to use i dont know about sensors, and if its possible well the more precise its best.....

what i was trying to figure out was positions to the servo, depending on the tension i need the servo could move to some position, but seen a lot more useful and precise to use a sensor..

well the shaft is not that difficult.... i can use an cnc to make it work..

ive been looking for steppers and servos and ive only seen small ones. from 2.5kg/cm to 7.5kg/cm... i dont think that wolud be powerful enough...


and if you think that software is not complex??? even touhg im not like very good programming so i think it would hard to me jejeje.....

for now i got the 2x16 lcd display and the numeric pad....

well i think you are right, it would be better if i use a stepper instead of a servo right..... but i dont know if i cant get such a strong stepper.... probably id have to use some gear combination to get the output tension i need.

ok... the whole thing has this funcion.. pull a string to get some tension about 70pounds max or 50 min... so what i want is to select the tension i need from the pad, it will be displayed on the screen and then the servo will do the work to make the tension on the string....

my frist problem is hardware i mean to connect all this in one board, the software well i know it will be complex but for now i have to solve the hardware part

hi fellas..


look im new in arduino, ad i see is perfect for my project, but id like to know if its possible to connect a lcd display, a numeric pad, and also one servo motor, wich board is suitable for this, arduino uno or i have to use a mega board?? :o :o :o

yes ive seen that u need at least arduino mega and 34 pins to get the ipod lcd to work......... thanks

hi i have an ipod video in the garbage... so i want to recycle some parts example the lcd screen the screen its working very well but colud it be possible to connect it to an arduino board??

very instersting..... ok i will buy an arduino uno to see how it goes and how could i connect the steppers

ummm still im not taht good in electronics jejje but ummm im using bipolar 4 output each i need to connect for of them and i dont need them to get speed in fact what i need are the steps.. i dont know if im being compressible....

an extra is that for controlling the stepper i will need an extra output voltage.. each motor need 12v to start and arduino only gives me 5v so i need to connect the stepper to an extra device......

however my doubt now is that if ith arduino uno i can connect4 stepper is that im like lost u know reading arduinos page said that uno only have 12 outputs but you said that i can get 20 how is that??

hi buddy's look im trying to build a cnc router but i want and arduino board to control my cnc,,, in oder to do that i need to connect 4 step-by-step bipolar motors each one has 4 output wires.... i wa thinking abour arduino uno... or if i can not connect all in uno maybe an arduino mega...

but my first option is arduino uno....
