Not a new topic. I've read related posts but still require guidance. I am a novice in both the electronics and programming categories. Working through a couple Arduino Intro books as well as the Python Crash course. Decided to attempt the cactus.io weather station project. Want to ensure everything is working fine before a permanent build so am prototyping all the sensors on a breadboard. The initial hookup of the Adafruit BME280 worked fine. Disassembled to change locations. On the second hookup got the dreaded "Could not find a valid bme280, check wiring. Researched, uploaded I2C scanner which found the sensor at 0x50. Wonderful. However I'm afraid I have no idea how to use my newfound knowledge. Undoubtedly somewhere in supporting code, library?, a change needs to be made to alert the Freetronics Etherten board I am using to where the sensor is hiding. Not a skill I possess. Another obstacle encountered was the the arduino IDE doesn't allow me to open the suspect library as it is not an Arduino sketch - cactus_io_BME280_I2C.h. I have purchased another Adafruit BME280 as possible hardware workaround but I'd really like to solve this problem the right way. Hopefully I've provided sufficient detail without uploading code or pictures to generate knowledgeable solution. If not please reprimand and I'll attempt to supply any needed additional information. Thanks for your time!
NO you haven't ......the BME280 address is either 0x77 or 0x76 so you're finding some other sensor and not the BME280.
You MUST provide much more detail (not words) to get any real assistance from the more experiance members on this forum.
While you are updating your post include a schematic, not a frizzy thing showing how you will interconnect everything. Also post links to technical information on each hardware device.
I appreciate your help but I've just spent a couple hours trying to provide the details requested only to be blocked at a couple different attempts. I don't seem to be able to work within the restrictions of this forum so I'll have to search elsewhere. Thanks.
