Its is because when you lift it, the value is slightly changing and because in the serial monitor, they round it off and show you, that's why the number remains the same. maybe if you go to the next floor or something, then you might see a change.

@@VANTABL4CK Its my sensor thats broken. It cant read the temp, humidity, pressure, and the altitude

@@DichillDichill does it say that the sensor wasn't identified pls check the wiring? I had the same problem I think i didn't solder the pin properly or maybe i burnt it

@@VANTABL4CK I didnt soldered it

@@Dichill use 3.3v for the Vcc

That is correct. Some of these BMP/BME280 breakout boards have a voltage regulator to allow higher input voltages. The board in this video is obviously NOT one of those. 3.3V for this one.

the sensor gets the 3.3V from the arduino board, but the I2C lines operates at which voltage level? Can they damage the sensor? Thanks

@@fabricio.ferrari Not knowing what board you have; I would think it would be the typical I2C 3.3V. If so; no problem.

whew that was close thanks 😳

FUCK

This sensor can also use the SPI connection, which will allow multiple sensors to share the bus. You can see tutorials on using SPI by Googling for them, and you'll need an SPI library for the Arduino. I believe that on this sensor, SCL=SCLK, SDA=MOSI, SDO=MISO, CSB=SS. You use a different Arduino pin for each sensor's SS line, but the others are common.

there are diferrent versions of the board and some can work with 5v

@@IAmRedNez This doesn`t seem to be the 5v board. I think he is connecting 5v to the 3.3v poor board :((

@@sergiourquijo4000 maybe, good thing these boards are dirt cheap

There are many different versions of this sensor. If you are using the BMP280-3.3 then you cannot just connect it to the 5V - you need to use an Arduino with 3,3V

Rahul Sharma You can write the sketch that way. Here's a way to do this: Keep counting the number of times the button has been pressed in void loop() since the beginning. Suppose that the LED is initially OFF. So if the counter is an odd number (counter%2==1), turn ON the LED. Otherwise, turn it OFF. Its just one of the many ways to do this. I hope that it helps!

This specific button doesn't have that feature. But you can tweak your sketch to make the button work like a toggle switch.

You can plug up to 255 devices on those 2 pins. As long as they have different addresses, they will all show up. But you will have trouble plugging in 2 of the same screen for example, as they are going to have the same 'unique' address. (This can also be changed by changing a resistor on the screen / peripheral) I've personally made several devices using a screen (usually SCL SDA) and the BMP180 (the old version of this altitude chip) also SCL SDA, and it works fine. I've had 4 SCL SDA devices running at the same time on an arduino nano before, all off pins A4 and A5. The only thing i'd say is be careful how much power you are drawing from the pins overall. But definitely a display and this module will be fine.

@@nataliesilsbury1888 generally speaking you can only have 128 devices, unless you have 10 bit addresses. bit zero is used for read and write. the other 7 bits form the device address.

Phil Cox I've found that these cheap eBay chips aren't all that reliable with their namings, but if you've got the same chip as the one I have in the video then the library will work. Don't forget to change the I2CAddress as per the video, and I would definitely recommend soldering the pins on, as I don't believe it will work properly until you've done that. When I buy these sorts of chips off eBay I usually buy 2-3 of them even if I only need one. That way you can test between them to see if one of them are faulty. Cheers

Thanks Aidan, I'm hoping it's the solder too. The chip should be ok as I bought it from a recommended UK firm, not ebay. Incidentally, the Sparkfun library was the only one that worked (to a degree) compared to Adafruit and a couple of others I tried.Really appreciate the reply.Best wishes,Phil

Good morning (or evening), I managed to get the sensor to work so thought I would share my experiance. I gave up trying to get the thing to work on I2C and wired the Arduino for SPI, changed the two lines of code in the sketch to switch over to SPI: //For SPI enable the following and dissable the I2C section //mySensor.settings.commInterface = SPI_MODE; //mySensor.settings.chipSelectPin = 10; And it worked a treat (not forgeting to select the Baud rate to that of the Sketch). I'm convinced this would have worked before soldering but I've soldered anyway to rule this issue out. The altitude is reading 243ft on average and I think this may have something to do with the pressure reading at my location so I will do some sums. All this can be accounted for and factored into the results as long as I know what I am dealing with. My only grumble is the % relative humidity is reading zero so ssome more research required. Next bit of the project is to add an SD card so I can record the data from the balloon flight. Thanks for your help again, much apprecited. Best wishes Phil

2501Pearl I think you would have to do it using a counter for how long your finger was on the sensor, then once your finger leaves the sensor you have the program decide what to do based on the length of the counter

Nathan Jackson yeah, that's how I am currently doing it! It's working pretty well so far

You reckon a basic timer? Will have to try then...

You can write something like: long totalTime=0; long touchON=millis(); if(digitalRead(touchPin)==HIGH) { while((digitalRead(touchPin)==HIGH) continue; long touchOFF=millis(); totalTime= touchOFF - touchON; } So this totalTime will give you the time in milliseconds.
