Using Multiple Devices with Arduino


hello experts ,

this sandeep , new platform , started learning 4 days ago .need project.

as per project requirement have run 2 linear actuators, 4 small push pull electromagnets , 1 dc motor using arduion (mega per research not sure difference) , inputs provided nextion 7 inch touch display module(kindly suggest if there other bigger displays(4 or multi-pin) out there "not shield").

i have been doing little bit of research on choosing right components , got know have use relays max voltage supported board output 5 v , motors 12 v each.

requesting suggestion on best available products [cant go expensive ones  :(  ] project .

would appreciate on .thank in advance.

there library 7" display.  can used both uno , mega2560.  display needs own  5v,2a supply.  (arduino power in not enough)
 
you'll need drivers (h-bridge) motor(s) , maybe magnets (if need both push , pull) otherwise logic level mosfet can used.
linear actuators.. no info.. can't tell. need drivers.
external (12v..15v) power reguired.
