Well, this is just a small prototype so I do just need a small alternative. It will be also controlled by the Arduino after the sensor detects something.
So basically, when the IR sensor detects something, the Arduino will control the alternative linear actuator to push the object that was detected.
anw, do u think this idea is possible? pls correct me, i'm a student who is willing to learn more.
You could use a cheap hobby servo.
how it can be an alternative for linear actuator?
With a lever type horn and a rod, it can certainly move things in a line
how cheap is it?
Chinese products are mass produced so cheaply it is hard to make them yourself cheaper, unless you make the performance much lower.
A linear actuator is usually a motor, a gearbox, a nut on a leadscrew, a couple of limit switches all packaged in a neat unit. You could get all of those things and make your own.
i'm thinking abt DC Motor + Threaded Rod or Servo Motor + Lever Arm
Depends, I seen two for one US dollar, so 50 cents each
what will u recommend, DC Motor + Threaded Rod or Servo Motor + Lever Arm
Depends. How much force do you need? How far do you need to move. How fast?
How much electrical power is available?
In some applications solenoid can be best option.
To get good suggestions you need to answer the questions and tell what are you trying to accomplish.
Any links to where that's available?
Had to search again:
thats what i was thinking, i just dont know what the materials are and how can i connect it to arduino
Nice. (I'd better order two.)
im interested doing it diy
yup, but there's no available solenoid here, even in online. had to search another alternatives
google search for servo rack and pinion. You will see examples of things you can buy/make/3d print.
Weird place you live in if solenoids are not available but servos and arduinos are...
You can DIY, if it otherwise match your approach (which I don't know).
