I was just wondering if a very knowledgeable expert could just give me a simple yes/no or maybe answer to the following. I’mnot after detailed instructions, though any pointers would be appreciated especially as to the parts/modules required. I just need to at least know that this is possible with this system before I go off on a wild goose chase…
I have been tasked with a project and this is what I need to happen using the Arduino as a base:
• Push button control of 12 separate servos (or stepper motors?) each raising an arm.
So 12 buttons on a box each controlling it’s own servo.
• The servos need to simply move an arm through 90º hold it for a predetermined time i.e. 5 seconds then return the arm back to it’s original state. If it were possible to change the time the arm was held after being raised with a pot before the button was pushed, this would be a bonus but not essential.
• The distance from the button pushing to the servo arm waving is 30 yards, so is it possible to control the servos wirelessly using two Arduino’s one monitoring the buttons, the other controlling the servos.
Or would a cable be ok to use say a couple of 7 core cables to give control/power/ground or would the losses/interference in a cable not make the link reliable.
• Reliability, This is important. I know you can’t guarantee anything, but a stable function is a must so I realise that the servos need decent clean power/ground, but also the button pushing/servo waving must be as reliable as possible over this distance.
So in a nutshell is it possible to do this with the Arduino and thanks in advance for any advice as it’s appreciated…
