Using Multiple Devices with Arduino

Hello Experts ,

This is sandeep , completely new to this platform , just started learning 4 days ago .Need help with my project.

As per my project requirement i have to run 2 Linear Actuators, 4 small push pull electromagnets and one DC motor using Arduion (Mega as per my research not sure about the difference) and the inputs to be provided from a Nextion 7 inch touch display module(Kindly suggest if there are any other bigger displays(4 or multi-pin) out there "not shield").

I have been doing little bit of research on choosing the right components and got to know that i have to use relays as the max voltage supported from board output is 5 v and my motors are 12 v each.

Requesting your suggestion on what would be the best available products [cant go with the expensive ones :frowning: ] for my project .

Would truly appreciate your help on this .Thank you in advance.

There is a library for that 7" display. It can be used with both UNO and MEGA2560. This display needs its own 5V,2A supply. (arduino power in not enough)

You'll need drivers (H-bridge) for the motor(s) and maybe also for the magnets (if you need both push and pull) Otherwise as logic level MOSFET can be used.
Linear actuators.. no info.. can't tell. probably need drivers.
External (12V..15V) power will be reguired.
