How to power my Project?

Projects General Guidance
1

First time using Arduino for my project and I'm not familiar with wiring electrical components either. My Project mainly includes 2 outputs.
Output 1: Linear actuator DC 12 V.
Output 2: Heating element band heater 110V.

So, how do I Power the Arduino which is 5V and the other two from the main source(110~120V) at once without burning them?
Thanks,

You need three separate power supplies for the Arduino, the heater and the linear actuator.

You also need either relays and/or a suitable motor controller to interface the heater and actuator to the Arduino.

So there isn't a way to power them independently but from the same power source?

Sure, from 110 VAC, which would power the heater directly.

You will need a hefty 12V power supply for the actuator, and you could use a step-down converter to go from 12V to 5V for the Arduino (to the 5V terminal), like this one.

For several reasons, it is not a good idea to apply an electrically noisy, 12V motor power supply to the RAW power input of an Arduino, even though the Arduino specifications suggest that this is possible.
