Arduino Windspeed Anemometer or Redneck Speedometer? 

Glad it helped!

I did get a few funny looks driving down the street... :-)

I'm not surprised, great stuff! I think you should have put an even bigger one on the roof. That would definitely have got some strange looks. Keep up the great work.

Nice work!

I'm mostly learning as I go. Enjoy!

Thanks 😁

It should. You would just have to adjust the values for the interference from the tube.

Using an I2C module makes it much easier. Try Robojax ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-q9YC_GVHy5A.html

@@ScienceFunInnovations thanks sir

Yes. It can be mounted in any orientation.

I haven't opened it up. I don't think it would open without breaking the plastic.

@@ScienceFunInnovations Thanks for replying. Possibly would you be able to test it as a motor by applying DC voltage from a variable supply source to check it working i.E operating voltage, current, RPM, and coil's internal resistance probably it will be easier to find the motor without physically looking at the motor. Thanks again, really appreciate you replying back to my comment

Speed vs. Voltage? The manufacturer included a table of speed vs voltage.

@@ScienceFunInnovations thank you for your fast response. I meant the values on column “D” on the excel sheet, how did you get these values?

I haven't done much with 7 segment displays. Perhaps a future video...

Sorry, it has been too long since I wrote that code and I can't find the files.

//Connect gnd to gnd, Vcc to 5V, SDA to A4, SCL to A5 //Connect anemometer red to A0 and yello to gnd #include #include #include #define BACKLIGHT_PIN 3 LiquidCrystal_I2C lcd(0x27,2,1,0,4,5,6,7); float windspeed = 0.00; void setup() { lcd.begin (16,2); lcd.setBacklightPin(BACKLIGHT_PIN,POSITIVE); lcd.setBacklight(HIGH); lcd.home (); lcd.setCursor (0,0); lcd.print("Wind Speed (MPH)"); pinMode(A0,INPUT); } void loop() { windspeed = (analogRead(A0) * 73.0 / 512.0); lcd.setCursor (0,1); lcd.print(" "); lcd.setCursor (0,1); lcd.print(windspeed); delay(500); }

It seems to just be a regular DC motor with a windmill. The voltage from the motor increases with wind speed. There are some videos on RU-vid on how to make your own using plastic Easter egg shells. Good luck!

@@ScienceFunInnovations thanks for your comments, have a nice day

Oh man, that was so long ago. I think I just got it from the library manager in Arduino, think it is called LiquidCrystal now. That's the only library that I have installed.

Are you getting an error message?

@@ScienceFunInnovations the error says that it couldn't find the LCD.h in the library.

@@RobsterCWell hey, did you know how to charge the LCD library?

@@vianeyximenamartinezvite2848 maybe it's because his version was different than mine. But once I got the code written, the error message said that the LCD header was missing. I was just following the error message.

@@RobsterCWell I got the same error as you do, how did you solve it?

Which library? The one for the LCD screen?

@@ScienceFunInnovations Which file library did you use for LCD.h? I have downloaded a few for the screen type and LCD and still won't compile.

Also it doesn't like the set Backlight line, lcd.setBacklightPin(BACKLIGHT_PIN,POSITIVE), dosen't understand "POSITIVE".
