Yours looks awesome. Thanks for sharing.

Yes, just eliminate the temperature and humidity sensor from the hardware and eliminate the code that supports it.

Yes, just eliminate the temperature/humidity sensor from the components and within the code.

I sent you a private message. You should see it under your Instructables profile.

Here is my latest code. It has a few extras with the SMS Message and Email:/** * This Arduino Project will monitor a reed switch attached to any door/window to determine if the door/window is opened or closed. * It will also capture the temperature and humidity from a DHT11 sensor. * It logs the status of the door and the DHT11 sensor in Google Doc and after dark it sends SMS messages when the door/window is left open. * It also makes use of the TimeZone database to set the internal system clock to accurately measure time. * * Major components of this project were derived by observing various examples on the internet espically from Instructables.com */#include <ESP8266WiFi.h>#include <ESP8266HTTPClient.h>#include <ArduinoJson.h>#include <TimeLib.h>#include "…

Unfortunately due to some family matters I was not able to look at it yet. Hopefully tonight or tomorrow night. Sorry

I was able to find some time this evening to turn on the system. I didn't have any issues with it logging the reed switch. I also have an EPS32 that I might try the code on tomorrow if I have enough time but as far as the ESP8266, everything is still working as layout in the Instructable. I did modify the code once to send SMS messages when the door is open after a certain timeframe (9:00 PM EDT). Would you like to see that code too?

I'm not sure by just looking at it. I'll have to test it out myself. Unfortunately I do not have the hardware with me at this time. I will do my best to get access to the hardware this week. However, if you don't hear back from me by weeks end then please drop me a little reminder.

Do you have the 10k ohm resistor connected to the reed switch? If not, that is probably your problem. Also, I bought several inexpensive reed switches and found that at least 1 of those was faulty. So, if you are confident that the reed switch is properly connected to the 3.3 volts, ground and the 10k ohm resistor then you may just have a faulty reed switch. As for off-line recording of the events, I actually have not tried off-line storage, so I can't provide you with any guidance on that subject.Good luck!

Great job. Why did you need to put a capacitor on that circuit?

Hi PierreV16, For the 6 servos that I used in my creation I was able to run all of them off of the 5V from the Uno but if you are going with 12 servos then I would think you would need to power them separately. Good luck and please let me know how it turns out.

Yes we do. Do you have them too?

Oh yes, the comment is incorrect. Originally we had planned on having 8 eyes but later settled on only 6. Therefore the comment should be changed to say "Move all 6 servos". The reason we eliminated 2 servos is because the interior of the pumpkin we used got really tight with only 6. If you have a larger pumpkin you can have 8 servos but you will need to change the servo array to hold 8 servos and the for loops would also need changed from 6 to 8.Thanks and good luck.

Cool

Thanks

Yep, the kids love it and so does dad!

Yes, that would work well. In this case, however, they move fast to surprise the kids. ;-)

Thanks

I can't seem to get this to work. Anyone have any tips?

Does this camera have the ability to stream video or just take pictures?

I love your design. I was wondering how you took apart the hamster ball?

Thanks! We do have both the dark side and droid develper. Bought them new in the 90s, I think. Dragged them out of storage to let the kids play with them.
