Title: Things i need to set up the transmitter and receiver system
Post by: Oreilly73 on Feb 10, 2019, 10:50 pm
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?

...R

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 (https://www.adafruit.com/product/1095) will work.

But for just a meter, consider using wire.
