I am starting my first project and I would like to prototype and design it on the Arduino first and then have a some small batches made in China.
The concept of what I am trying to do is pretty simple. I’ve attached a little diagram to this post. I want to be able to turn a dial and then have a motor or actuator pull a cable with a weight.
- The weight will probably be around 5-8 lbs.
- The movement will be stepping, If you turn just a little it will move just a little.
- The motor will move not 1:1 but at some other ratio. So I can just turn a bit to get a certain distance of pull on the cable
Q1: What arduino should I buy? There are some with many features and some that seem to be really minimalist. I want to be able to do more projects in the future so from what I understand, if I want to use it for prototyping, I can buy a feature rich version and then all my code can be uploaded to a paired down chip with just the sensors/actuators needed for the final project requirements?
Q2: My final product may use a cheap, bulk rotation sensor from the factory, or may need a stronger actuator/motor to pull the cable. When I prototype is it okay to use sensors and motors provided with an Arduino kit, even if those will not be the ones used in the finished product? Will the code I use for controlling work across different sensors/actuators, or when I work with the Arduino, do I need to have the REAL components?
Is there any other advice for how to bring this project from concept to reality? What is the workflow that you guys use?
