With Instructables you can share what you make with the world, and tap into an ever-growing community of creative experts.
Thank you! ;-)That's the idea! I have learning from doing it, and I usually write the tutorials in the exactelly order that I build them. My goal is to share what I learn! Your comment is a nice and important one to keep me on this track! Salut from the south of the world! ;-)
Combining Inputs and Outputs
Circuit Displays Internet Data
Circuit Triggers Internet Action
Once I do not have a Neo Pixel, I used a RGB LED to display weather condition as:RED: RainBLUE: CloudyGREEN: Clear
I put both together, button and PIR motion detector, sending the data to Adafruit. The button data will appear as "1" and a motion detection as a "2".

Thanks a lot!No, I have not, sorry. I only tried voice control on a local network. In this case there is no problem with delays.
Hi. Go to the file: stationDefines.h and change the UTC_OFFSET variable for the one correspondent to your time zone. t in you/* TimeClient */const float UTC_OFFSET = -3;I suppose that in your case, should be:const float UTC_OFFSET = -4;Regarding LOCAL temperature, you can get the DHT reading directly in Fahrenheit, changing the line:localTemp = dht.readTemperature(); // Returnes CelciustolocalTemp = dht.readTemperature(true); // Returns Fahrenheit.
Another point, to change the information received from Wunderground site from Celsius to Fahrenheit, you must change the variable IS_METRIC, from true to false (this declaration is on file stationCredentials.h):const boolean IS_METRIC = false;You must also change the oC to oF at display routines at main code.
Hi, Great job and Thanks a lot! for your tips!I never rotate the camera, but I suppose that you can do it easily adding a parameter at Video Streamer command line.At the original command used on the tutorial:LD_LIBRARY_PATH=/opt/mjpg-streamer/ /opt/mjpg-streamer/mjpg_streamer -i "input_raspicam.so -fps 15 -q 50 -x 640 -y 480" -o "output_http.so -p 9000 -w /opt/mjpg-streamer/www" &You can use parameters as:-rot : Set image rotation (0-359)-hf : Set horizontal flip -vf : Set vertical flipYou can try set vertical flip, adding -vf to command line:LD_LIBRARY_PATH=/opt/mjpg-streamer/ /opt/mjpg-streamer/mjpg_streamer -i "input_raspicam.so -fps 15 -q 50 -x 640 -y 480 -vf" -o "output_http.so -p 9000 -w /opt/mjpg-streamer/www" &
I am very happy to help! ;-)I love Arduino, NodeMCU. RPi. Those are great devices! I hope you like the book. And if you like and can give it a review at Amazon would be great!Thanks a lot!Marcelo
Hi, I am working with multiple files at Arduino IDE. 1. You must download all files from the folder (There are 6 flies on there): https://github.com/Mjrovai/ArduFarmBot-2/tree/mast...2. Note that your folder must have the same name as the main .ino file:ArduFarmBot2_Ext_Auto_Ctrl__V4_0.ino3. In your computer, when you click on the above file (inside the folder with same name and including all other 5 files), the Arduino IDE will open and you will see a similar situation as the photo attached (Note that will be 6 "Tabs", one for each file). One of them is the "defines.h". Please let me know if you got it.Thanks
really Great!!!! ;-)
Hi Luis, Sorry, but I am not sure that I understood your doubt. I suppose the is not working because everything was developed with this OLED in mind. From Underground come graphics for example, that must be worked to be presented on anothe display. Also note that must be a grphical one.
IoT Made Simple: Servo Cont...View Instructable »
This project was developed to show how to connect the RPI and an Arduino. But each one perform specific tasks. For example, to connect the camera, sensors, connect with ThingSpeak.com you only need the RPI.
is it possible for you to check it with another NodeMCU? When I bought mine, I received 3 units and one of them never worked well.
During development phase, you will be powering the NodeMCU thru the USB cable connected to your computer and the NodeMCU Vin pin should not be connected to breadboard power raid. The external 5V will be connected to breadboard power raid and will supply 5V to all devices, except to NodeMCU. When you will use the ArduFarmBot on field (after the Sw is loaded), the only power source will be the external 5V power supply and you should connect nodeMCU Vin to breadboard power raid as showed on electrical diagram (the red cable).Note that the NodeMCU 5V pin should be DISCONNECTED all time. We will not use it.
sorry, the NodeMCU 3.3V pins must be all DISCONNETED

Yes. The NodeMCU can drive the Max7219. But you will have a lot of work to write the code to present letter by letter the date on displays. I really think that such weather station application is more suatable for a graphic display.Anyway, you can for example look on this link for more information:https://frightanic.com/iot/nodemcu-max7219-8x8-led-matrix-display/ThanksMarcelo
Hi.you can follow this instructable:https://www.instructables.com/id/IoT-Connecting-th...
See the:Step 8: Connecting the RPi and the Arduino Using Serial Communication
Great and simple project. Also works fine with NodeMCU.==> Data to I2C SDA (GPIO 0 ==> NodeMCU D3)==> Clock to I2C SCL (GPIO 2 ==>NodeMCU D4)// Clk to I2C SCL (GPIO 2 ==>D4)
Voted! Very cool!!!!! ;-)
Thanks for your words! ;-)Seems like your NodeMCU is sourcing more current that he can get from your power supply. When it happens it resets. Try have a 2A 5V DC power supply sourcing your circuit. Check if all connections are correct. Better all devices be sourced by external power supply. If does not work, disconnect the devices one by one and check again.
Perfboard Hackduino ($8 Arduino-compatible Circuit)
Hi. I did not use sliders, I used buttons with pre-defined angles. I never built pages with slides and I do not have a code, sorry.
Yes. The tablet is in the same network. The webpage HTML has the IP address of my RPi as explained on the tutorial.
I used the RPi V3. It has WiFi and does not need an external adapter. If you use previous versions of RPi you will need an WiFi adapter inserted. Both ways will work fine.
GESTURE HAWK : HAND GESTURE CONTROLLED ROBOT USING IMAGE PROCESSING AS INTERFACE
This project as Was developed works only on a local Network. To use it on another network you will need a static IP (contact your Web provider for that).
You do not need a "cable" to control your RPi once it is connnect to your local network via WiFi.

Thanks a lot! ;-)
Yes, I suppose that you can do it. No, you do not need the <xmp>. I only used it to show the HTML code properly. You myst take it out when you run your code. Thanks
thanks a lot! I correct it on the text:Now, let’s move all files to this new directory:sudo mv /*.cgi /var/www/cgi-bincd /var/www/cgi-bin
Please check if you have a sub-directory (/images) with the icons under the directory where you have index.html (see photo)

I founded how to do it. I will included it on my post!for example: allDevices = new Switch("All Devices", 84, allDevicesOn, allDevicesOff); bedRoom = new Switch("Bed Room", 85, bedRoomOn, bedRoomOff); livingRoom = new Switch("Living Room", 86, livingRoomOn, livingRoomOff);and of setting the relays properly!this is the way, correct?thanks a lot again ;-)
Great work! Works fine. Thanks a lot!I also wrote a tutorial about Alexa and NodeMCU. I am trying to figure out to give Alexa group of commands, like "Turn on all lights", etc. Do you know how?ThanksThanks!

First of all I can not have weather condition and also forescast it for some days only using internal sensors. By the other side, web services can not delivery data about the temperature inside my house. That's because both data are complementary and not redundant.
Thanks a lot and good point. I never tried the BME280, but certainly I will give it a try. Thanks for this! ;-)

R-PiAlerts: Build a WiFi Based Security System With Raspberry Pis
Sorry Kovalski. All the idea of this project was not to use high level language (as Python). If you want to do it, my advise is to start from scratch. Make more sense for you to follow other robots projects already done with Python.
