Hey,

This is my first project btw. So my objective is to have a transmitter hooked up to the arduino pro mini with a button and send the signal to either a mega or uno with the receiver which activities a solenoid. I would like to know how would i acheive this and the materials I would need. I'm in the us and i'm pretty sure i'm the 433 MHz. https://www.amazon.com/433Mhz-transmitter-receiver-Arduino-control/dp/B0129V2OZQ/ref=sr_1_2?s=electronics&ie=UTF8&qid=1549835336&sr=1-2&keywords=rf+transmitter+and+receiver+for+arduino&refinements=p_36%3A-300 . Is the module i thought i would be using.  Thank you

Look at something like this to get you started:

Post a link to your chosen solenoid. It may require a simple driver circuit.

What distance will there be between the transmitter and receiver and will there be any obstacle between them?

Two or three hours spent thinking and reading documentation solves most programming problems.

This looks very helpful. I've never used a bread board before but I think the wires line up vertical to the pins of the receiver which then i can follow to the uno. The transmitter is a little different. Are there 2 seperate wires connecting to both the second and fourth pin of the transmitter? What battery should i get if i want these two to be portable? If i used the arduino pro mini (5v) instead of the uno for the transmitter could i make that work? https://www.adafruit.com/product/2776 is the solenoid i thought i would use.

No more than a meter

For your purposes, you don't need an Arduino, as these self contained units will work.

But for just a meter, consider using wire.
