alleebell I won't carry it even if it is FREE! It reflects my ignorance of what it says on the bag, Like you said - it has no meaning! 即使它是免費的,我也不會攜帶它!它反映出我對袋上的字一無所知,就像您說的那樣-沒有任何意義!

Q: to which pins can I connect the BME280 sda scl?

Preguntado por Frontloop sobre 2020-06-26 12:03:22

alleebell D1 and D2 are internally wired for the OLED and it is not accessible at the header. I suggest using D3 and D4 and use the wire.begin(D3, D4) to declare it.

alleebell I bought four modules recently. None of them worked at described by other users. They are useless! I used the FastLed library and the "blink" scratch to test one LED at a time with R, G, and B color per LED. I cannot get one board to display one color with all 64 LED. Junk!

alleebell I received four last week. I used WS2812 strip before. I am not able to get even one module to work correctly with Arduino nano. I am going to do more research before I contact Customer Support. based on what I read here, this product has reliability "issue".

Q: Where I can find a software program to test the delivered product?

alleebell I wish the description of this kit tell us where DHT-11 and the OLED are connected. My finding: The DHT-11 is to pin 5. For the OLED, SDA is to pin 2 and SCL is to 14. The OLED is SSD1306 (it is on the package).

Q: Where to connect I2C?

Preguntado por r.vanpoppelen sobre 2018-09-23 11:20:49

alleebell The description has no mentioned of I2C connection! However, one can use GPIO 4(SDA) and GPIO 5(SCL). At the setup, add this to declare the two pins - wire.begin(sda, scl). I think that's why GPIO 4 & 5 are easily accessible on the PCB. Run I2C scan to confirm the I2C device(s) are connected correctly. If you run it once and you don't see the device, I suggest swapping the declaration and try again. Good luck!

alleebell Are you able to use the OLED? I did an I2C scan of the board and find nothing. Can someone provide a little info on how to use the OLED? As of now, I have no idea how to use it. I searched the Internet many times and find nothing helpful regarding OLED on this module.
