motor driven by optical sensor

[gianlucax90]

Bye to all,
I have an electronic problem since I am highly unprepared about it!
I made a station assembler powered by vibro power supplies.
Now it's time to integrate sensors.
I attach an image to clarify some points (picture on top right).
the sensor will have to have the task to stop the engine of "b" in case the latter is not blurred and let it restart in the opposite case.
with a tolerance margin of 5 seconds, i.e., if the sensor is not blurred for 3 seconds and at the 4th second the b engine must not be stopped.
is it feasible? someone can help me understand what components buy and what kind of circuit realize?

thanks to everyone in advance.

in my opinion the ideal solution for you is an arduino board, simple to use and simple to program.

It's a generic user card with both analog and digital input and output, the development environment is very simple and the program you need would reduce more or less to a handful of code lines;

if input 1 fake then
count 5 seconds
if input 1 still fake then turn off output 1 (turn off the engine)

if input 1 true and output 1 fake then turn on output 1 (light the engine if it is turned off but the sensor from the ok)

the card is quite expensive, almost 30 euros, but it pays off with the ease of programming and with the very abundant documentation
There are also several manufacturers that produce all standard and perfectly compatible and interchangeable cards, so even in case of failure or closure of a manufacturer there are no problems for a quick replacement

arduino has no power to interrupt. You need to use it to fly a relay.
However arduino is not an industrial card. It can be good for a machine not too "important", but for example you cannot do the automation of a nuclear plant. ..:tongue:

However, without disturbing programmable systems, just a relay with timer.
something like This is, but I didn't see the technical sheet well.

Yes, arduino is the brain, to close large currents, they need the kidneys, unless, for example, the motor is not driven by inverters, in that case it is enough to control one of the inverter inputs.


the programmable cards are very comfortable for the set-up and tuning phase, certainly if the machine is produced in large numbers (over 100 pieces) it is best to make the custom chip rather than put a complete arduino in each machine (which, however, gives the advantage of being reprogrammed and up-to-date)

thanks for the simple explanations! (At least I understand something)
the machine for the quantities it produces will not be reproduced in series but at most a replica will be made.
So I'd say with arduino we're here.
I also tried to do a research on rs comp. for the Temporary relays(I looked at those from 20 euros).
the engine that I am currently using goes to 6 v but wanting I could check the part before the power supply that is to 220 v.sbeglio?
If that were someone kindly, could I have a draft of the schematic?

the tension has nothing to do with... What engine is it? What currents absorb? What? regime?
