You must have installed Python version 2.7If you have a later version installed, uninstall it. Download Python 2.7 and install that.Another thing I discovered is the Port entry for OTA is the board ID plus its IP address.I found it difficult when I have several systems around the place.In the Basic OTA sketch uncomment the line (below) and add a name, this will show up on the port listing:-// Hostname defaults to esp8266-[ChipID] ArduinoOTA.setHostname("water"); // UNCOMMENT THIS AND GIVE A NAMEDo the same in the main sketch, in the Setup section, add the same name like below:-ArduinoOTA.setHostname("water"); // ADD THIS ArduinoOTA.onError([](ota_error_t error) { ESP.restart(); }); //added for OTA ArduinoOTA.begin(); ...

In the app, look in the widgets for 'Notifications' choose the type of notification you prefer and add it to the app.You will have to read up on how to use it on the Blynk website.
View Instructable »Yes I found these a bit unstable.I did discover, by researching this device and the NewPing library, there is a multi ping function which then gives an average of your selected number of pings. Use instead of the normal ping function.unsigned int echoTime = sonar.ping_median(5); PingDepth1 = sonar.convert_cm(echoTime); delay(100);I found this stabilised it.Hope this helps.

HC-SR04 is ok.
If it has a ping and echo pins, you could probably use it.
View Instructable »Yes, Depth1 and 2 are the depths of the tank from sensor to the bottom.Distance1 and 2 are the (sensor measured) distances from the sensor to the top of the water.Subtract Distance from Depth and you have the depth of water.
- ItsGraGra commented on ItsGraGra's instructable Water Tank Levels by WiFi on Your Phone6 months ago
depth1 is the distance from the sensor to the bottom of the tank. Distance1 is the distance measured. Subtract distance1 from depth1 and you have the depth of the water. Multiply that by the base area and you have the volume.
Q1, yes. Q2, on a D1 power the board using a plugPak and the 3.3v pin can power the sensors. Don't need the dc-dc supply. I have now changed mine to run from a USB plugpak and the sensors from the board 3.3v pins. I will be updating this instructable when I get time.
View Instructable »First off, does your code compile? Use the left button in the IDE. Check all the wiring, what there is of it. If it compiles OK, upload it to the board, which you should have selected under the 'tools-boards'menu.If it doesn't compile check where the error is, it will be highlighted. Let me know what happens.

This is a great start. You can avoid the light bleeding through to adjacent chambers by painting the inside with silver paint.Avoid cutting the LED strip by buying he correct pitch strip; they come in 30, 60 144 per meter, get one that fits and/or design to fit the strip.Use a ESP826 NodeMCU board, has built in WiFi and then you can update time with NPT from the internet and control using Blynk or the like.Add a calendar for the date.see the one I made for inspiration here : https://www.instructables.com/id/NeoPixel-Clock-1/

Thanks for the compliments. Good idea for flow rate meter, good luck with tests.

No. The boards send and receive the ultrasound ping. It also then calculates the time taken and converts that to centimeters.

I did mention setting up a 'local' Blynk server was beyond the scope of this instructable.Nevertheless I will point you in the right direction.Firstly you do need to add the IP address of your local server on this line in the code:Blynk.begin(auth, ssid, pass); Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,107),8442); //IP address of RaspberryPi on the local network, port 8442.If you're using a Pi it should inform you of it's IP address in the info bar at the top.The above IP is mine, yours will be different. Watch the commas and spaces.Also on the Blynk phone app tap 'log in'tap the icon that looks like a set of traffic lights, this should allow you to enter server settingspush the slider switch to 'custom'enter the same IP address as in the Arduino IDE. i.e. 192.168.1.107In t...

Blynk is fantastic, specially if you set up a local server,then you have unlimited energy. Plenty of tutorials on the net using a RPi.
Good luck with your project.
The Arduino doesn't have a power supply. I used a 9v plugpak into the mains, the converter gives me 3.3v to power the Arduino and sensors.

- ItsGraGra commented on The Juliart's instructable Super Glue Accelerator and Filler1 year ago
Fine sawdust mixed with PVA wood glue makes a great wood filler.
View Instructable »Super glue cures super hard.When sanding (by hand) wood or anything softer than the super glue, I find the super glue area is left higher than the surrounding wood. Even when using a flat sanding block.Machining is ok, no problem.I have built model aircraft with super glue, it's very quick and easy but as the super glue soaks right through the balsa wood, sanding is a real problem for the reason I mentioned above.

These sensors have 'ping' and 'echo' connections.Why are you not using the 'echo'.You could also use the NewPing library, better timing and simpler code. get here: https://bitbucket.org/teckel12/arduino-new-ping/do...Water roof sensors are available with board for about US$5 on Aliexpress:https://www.aliexpress.com/item/K02-JSN-SR04T-inte...And if you're not using WiFi, why 2 Arduinos? Run your sensor wires (4) direct to the Arduino in the house.
