Request: PIR Motion Sensor #325

Closed rraulinio closed 7 years ago

rraulinio commented 7 years ago

I recently got a motion sensor for my Arduino Uno and I'm interested in programming it via Gobot, because I've done everything so far in Gobot. Are you able to dev something in the next 2-3 months? Because I would like to use this application I'm making in Golang+Gobot as my bachelor's degree project. :) The sensor is this one.

Looking forward for an answer!

Hi @rraulinio please take a look at this feature branch with initial PIR sensor support: https://github.com/hybridgroup/gobot/tree/feature/devices/pirmotion

You would use it as follows:

package main

import (
    "github.com/hybridgroup/gobot"
    "github.com/hybridgroup/gobot/drivers/gpio"
    "github.com/hybridgroup/gobot/platforms/firmata"
)

func main() {
    firmataAdaptor := firmata.NewAdaptor("/dev/ttyACM0")

    sensor := gpio.NewPIRMotionDriver(firmataAdaptor, "5")
    led := gpio.NewLedDriver(firmataAdaptor, "13")

    work := func() {
        sensor.On(gpio.MotionDetected, func(data interface{}) {
            led.On()
        })
        sensor.On(gpio.MotionStopped, func(data interface{}) {
            led.Off()
        })
    }

    robot := gobot.NewRobot("motionBot",
        []gobot.Connection{firmataAdaptor},
        []gobot.Device{sensor, led},
        work,
    )

    robot.Start()
}

Note that this branch is based on the dev branch, and so will not be compatible with the current master. Please give it a try if you have a chance.

rraulinio commented 7 years ago

@deadprogram I will test the PIR sensor and come back with an answer. Tested the branch files, everything works fine (after editing main.go as you said).

rraulinio commented 7 years ago

Nope, the function doesn't work. The sensor is not detecting anything or it isn't starting, don't know exactly. If I test the sensor via Arduino's compiler, it works perfectly. Nothing via Gobot. Also, if trying to close the program (ex: ctrl+c on windows cmd), it freezes, and I need to restart the cmd (this happens ONLY IF I INITIALIZE A PIR MOTION SENSOR). Please help me asap!

deadprogram commented 7 years ago

Hi @rraulinio I had to make another commit to correct an error in the original code, and I just tested it with my HC-SR501 sensor. Please give another try when you get a chance.

rraulinio commented 7 years ago

Hi, are you sure that you commited the right code? It still doesn't work and you forgot that fmt.println in an infinite loop...

deadprogram commented 7 years ago

The correct code is now checked in. This is my output:

rraulinio commented 7 years ago

Mnope, still not working. Not detecting any motion at all, don't even know if it's calibrating or something... Be sure that everything is plugged corectly, because as I said, it works when runned by Arduino's compiler. I'm running this very basic example and nothing... led on 13, sensor on 7... nothing. I don't know...

deadprogram commented 7 years ago

I know my HW is plugged in correctly, and as you can see form the above output is working. There is no calibration on the sensor from software, it just does it's thing.

rraulinio commented 7 years ago

Mnope, tested again via Arduino's compiler and works perfectly. Reuploaded Firmata. Testing via Gobot, not working. I'm out of ideas...

I'd check your version of Firmata. Where did you obtain it from? Also verify your pin, my test used digital pin 5, you mentioned you were using digial 7. Also make sure you are using correct 5v voltage.

I used an Arduino Uno. Are you using some other Arduino variant?

In any case, check all the above, since we know the code itself "works".

rraulinio commented 7 years ago

Firmata is at ir's latest version, from October 2016, being updated in Arduino's compiler and then uploaded by me. I'm sure that the cables are plugged in ok and the sensor works, because as i said, if i run "pir motion example on arduino compiler" it works perfectly. I'm using Uno, compatible with Arduino... it's the same thing.

rraulinio commented 7 years ago

I really can't see why it does not work, mostly because it worked for you. Are you sure that you uploaded all the corrections for the code? Maybe you forgot something, don't know.

deadprogram commented 7 years ago

Did you verify that the Gobot firmata_blink.go program works as you expect? Try testing that on the Gobot dev branch as sanity check.

I use ConfigurableFirmata with most everything activated (DigitalIO, AIO, I2C), usually uploaded via the latest version of Gort (https://github.com/hybridgroup/gort). Also have tested using Arduino101 using the Firmata uploaded via IMRAA.

If not, something else must be different on your setup. Are you just running the https://github.com/hybridgroup/gobot/blob/feature/devices/pirmotion/examples/firmata_pir_motion.go program, or something else?

rraulinio commented 7 years ago

Everything runs properly. In parallel, I run 3 leds and a buzzer from the breadboard, so yes, everything is allright at this point. I'm running that example, yes.

deadprogram commented 7 years ago

This is my hw setup: img_20161031_094346

rraulinio commented 7 years ago

Uploaded firmata via Gort, retested... still nothing. Tested in that very basic example... nothing. It can't be possible that the configuration could have something, because in this case, running it via Arduino's compiler wouldn't work at all, in the first place. It's crystal clear that the problem is either at my version of firmata (don't think so, it's the last one), either on something related to gobot. Please post 2-3 more pictures, with the connections of wires and all, so I can make a check with yours.

deadprogram commented 7 years ago

When you said "Tested in that very basic example... nothing" did you mean that the firmata_blink.go example did not work for you?

deadprogram commented 7 years ago

Here are my connections to the HC-SR501:

img_20161031_100258

The OUT pin on the sensor is connected to the digital pin 5.

rraulinio commented 7 years ago

Yes, very basic example = firmata_blink.go. I'm gonna get back at it in a few hours (it's morning here in Romania and I need to go away from home with work).

deadprogram commented 7 years ago

Did the firmata_blink.go work, or not work?

rraulinio commented 7 years ago

Not work. Initialising and starting sensor, but that's it, no detection further on.

deadprogram commented 7 years ago

I was asking about the firmata_blink.go, not the firmata pir.

rraulinio commented 7 years ago

Sorry, I was in s hurry, didn't pay full attention. Yes, it worked perfectly, firmata_blink.

rraulinio commented 7 years ago

I will get back at it in about 6-7 hours. I think i'm gonna record a short video with the configuration and with the startup and email it to you on your account's address. Is that ok?

deadprogram commented 7 years ago

Sounds great, thanks.

rraulinio commented 7 years ago

No, I thank you. Than, talk to you via email and i will get back here with a new post with the solution when it's done (for others in the same situation).

rraulinio commented 7 years ago

Email sent, check your inbox.

deadprogram commented 7 years ago

You probably want to set the jumper to "auto-reset" right now looks like you are set to "no reset": https://www.mysensors.org/build/motion

The Arduino code from what I could tell in the video looks opposite to what I would expect. The HC-SR501 goes HIGH when motion is detected, and LOW when no motion.

rraulinio commented 7 years ago

So what should I do? I don't understand.

deadprogram commented 7 years ago

Switch your jumper to the "auto-reset" position, I suppose.

rraulinio commented 7 years ago

Switched, no change... still not working. Sometimes (not always), if I replug the red wire (GRD), it goes on and detects, and than goes off. After that... nothing. I tried every single posibility, with the jumper on L and on H, nothing.

deadprogram commented 7 years ago

I have a bunch of these same sensors, they are very slow to reset (needs at minimum 5 seconds) but generally reliable if you set the calibration. You for sure need auto reset or it will only trigger once.

I have tested successfully with a real Arduino Uno, a clone Arduino Uno, and an Arduino 101. I've also tested with a couple of different pins.

In any case, check your sensor, or your cables, or try another Arduino. Seems like everything is working as expected to me.

rraulinio commented 7 years ago

Ok, I will see, than. I will try to figure it out. Thanks for all the help, I really thank you. Hope this will help others, too.

Please let me know anything new you might discover.

rraulinio commented 7 years ago

Uno R3, made like Arduino. Is a replica of Arduino, it's around $6-7 here and does the same thing as an original one. :)) I've tested a lot of algorithms on it, made by me or not, and it works very well. I'm running Go 1.7.3 on Win.

rraulinio commented 7 years ago

No, I just can't make it work. I've tried everything, really everything. It doesn't work with Gobot... only with that Arduino's Compiler. I need to give up for now, I can't focus on this anymore. I will get back at it in a few weeks or something like this. Thanks again for all your help!

deadprogram commented 7 years ago

This device is now in the 'dev' branch. I am closing this issue, please reopen if needed, and thanks to @rraulinio for your work on this.
