We have two continuous rotation servos (SM-4303R), and need them to push a rod between the two servos down, then after a period of time, the servos need to bring the rod back up. All of this needs to be initiated by a temperature sensor (TMP36). it just needs to sense a significant temperature change (more than what changing air temperatures can cause due to direct sunlight), then start the cycle.
please help with this code.
..not very clear what kind of movement you want..(make a sketch)
It may be difficult to control the servos, as you control speed not angle.
please help with this code
You forgot to post your code
We are having a rough time finding code to turn both servos at the same time. They are continual rotation servos so they can keep rotating past 180. It needs to move that rod (in the rough sketch) down. These servos just need to rotate simultaneously for a certain period of time that would allow the rod to be set all the way to the bottom (of which we will test and change the actual time)
Your servos are not independent so you can control them both by the same output. You will need to use a transitor to switch the power on, but by connecting the transistor output to both servos the problem becomes one of just moving one servo, not 2.

Can you move one of the servos? If so, moving the other is exactly the same process. The few nanoseconds between telling one servo to start moving and telling the other one to start moving are unlikely to even be noticed.
Problem is we have tried multiple codes and have had none work. We are apparently doing a bad job of understanding when and what codes to utilize.
surely you jest. There are plenty of easy examples to move servos.
I'd suggest to buy some arduino books and read up on the basics. Here's one to start with
