I have no previous programming skills and know very little about electronics and connecting boards. My project concept is creating a small machine similar to the pick and place machine that is controlled by an input device ( like touch screen, or a 7 by 4 input pad ).
I have three months to learn arduino and build the machine. Is it possible to do it? If yes, where can I find codes are other useful resources to get started?
Please read the way the forum works; we don't just help you because you're a noob. Not saying that I'm not a noob, but just don't.
It can be done, but it would require a tremendous amount of effort. Soldering skills would be useful. Try getting something like the Arduino Starter Kit or the Getting Started with Arduino Kit (book separate). Those might help to get you started.
Well first I'd say you need to design a solution... that doesn't require either programming or electronics really. You need to define what it is you want to happen.
At least learn basic Arduino skills too though, as suggested above, and you'll probably want to experiment with how servo motors work since most robotic solutions use servos in the joints.
A pick & place machine operated by a touch screen is an immense project not a small one. If you are as much of a noob as you have described, I would abandon all hope for the 3 month goal. Learning just the basic knowledge of electricity, coding and components is a long and tedious road. I would suggest reading this forum and watching arduino tutorials on youtube to build your understanding. I pick & place will have at the least some motor control, that alone is highly complex stuff. Why such a tight deadline? fair to assume this sounds like an engineering course final project?
