I have recently started a project and wanted some advise please. Using a Arduino board, L298N motor module and a Nena 17 stepper motor, I have programmed the Arduino to rotate the stepper motor to 3 difffernt stop's. The idea is the stepper motor will rotate three different number plates on a framework.
I just want to pick some ideas if possible as I am fairly knew to the world of electrics and electronics'. Will I need some sort of stopping device to stop the number plates from turning after the motor has rotated to an interval? Also would I be looking at some sort of calibration on the motor to tell the home position?
If I have missed anything would be greatly for any sort of feedback.
Better to use a DC motor with a worm drive gearbox . Have tabs in the back of your mechanism operating micro switches to stop the motor in the desired positions .
The worm box means the plate cannot move when the motor is off
Paul__B the idea is for car shows etc, so the vehicle license plate is showing whilst on the road and when the vehicle is off road on a display the private, or show plates can be displayed at a push of a button.
Hammy that's another idea but the less components the better, I was thinking rather then micro switchs I could just simply fix a magnetic proximity switch that would activate and deactivate to the release the number plate.
Or maybe it ends with the car starting to talk to you and being equipped with a "turbo boost" button that makes it jump
Limit switch or magnetic sensor have the same purpose: tell the motor when to stop. Magnetic would be more reliable (contactless). Add second sensor for home: only one of the positions will also activate that one. This way you always know which plate is showing.
