Hi! I need to start project for my job. I knew little bit about arduino, but need help with this project. I have 10 maschines in my layout, this maschines have red alarm lights turned on when they stop (they make elastic straps), then workers need to see what happened with maschine and need to restart it. The idea is that they cant always see which maschine stopped to go to fix it. I need something that will collect analog data (maybe voltage from that red alarm lamp or something) and send it via bluetooth to one central station which shows on TV which maschine need worker to go see it. It can be anything like pc or tablet connected to big sceeen. But data need to be sent via bluetooth with names of every mashine like (P1, P2, P3…). If someone can help to introduce me with that and post some links or something that will help me. Thank you!
why can't you just have a red light above the machine that has a problem?
a guy from the telephone company said they mounted lights are the end of aisles with telephone equipment that would indicate a problem on one or more of the devices in that aisle which helped locate the failure quickly
if you want the hi-tec solution, what bluetooth devices is receiving these alarms and who is monitoring it?
and if you really need bluetooth, you may be better off with an ESP32 that supports WiFi/Bluetoorh
In English it is spelled machine.
Does the brightness of the red light indicate how severe the problem is? I mean if the red light is very dim, the problem is only minor, but if the red light is bright, the problem is severe? If that were true, it would indeed be an analog signal. But I suspect that is not how it works. The red lights are either on or off. That is a digital signal, not an analog signal.
If you do not understand something basic like the difference between analog and digital, then I suggest you are not ready to start this project. You should spend some time taking some basic science and technology classes.
By "bluetooth" do mean "wirelessly", but Bluetooth is only only type of wireless that came into your mind? If it must be Bluetooth please explain why no other type of wireless would be suitable.
with bluetooth you can send over a distance of maybe 10 meter.
I assume the machines have a bigger distance and maybe eletromagnetic noise is in the air and objects out of steel in the way which would reduce the distance.
If the wires of the red lamp can be accessed easily you could add a small interface to pickup if lamp is on or off.
second best method would be a fototransistor directly attached to the red lamp again with a small circuitry to get a clean digital signal.
What is the biggest distance between the most far away machine and your central display ?
Do you have WiFi in the machine hall already?
Then everything points towards ESP32-nodeMCU microcontrollers which have WiFi on board.
