Developing and Designing 🙏🙏

When we talk about Mechatronics, people think of PLCs, Machines and Robots. But it doesn't end there.

Can you design a system from scratch?
Can you program small gadgets like Microcontrollers to perform tasks? 
Can you use Python and Javascript in creating frontend and backend to control your system remotely?
Can you design a small circuit board that can trigger bigger machines to do some tasks and monitor each action?

I appreciate an opportunity to upskill myself in this industry. The Beast got unleashed 🙏🙏🙏.
