@inq If "size matters" for you, then you shoud check out Ivan Miranda who has built many 3D printers and used the parts to bootstrap his way up to ...

@jaz939 So, you're telling me that you have a sensor whose instantiation you're calling aqi and a second, different sensor whose instantiation you'...

@jaz939 It appears that you've directly copied the 'test' example for the library. So, the setup and execution should be OK as the example code wor...

@jaz939 I suggest that you insert some println statements into the .cpp file to determine exactly where the function: bool Adafruit_PM25AQI::read...

@fritigern Google yielded ... which has a diagram of linked ICs.

@zander OK, using a different library is probably the cause for the extra errors. Thanks for the explanation.

@zander Which include was spelled incorrectly ? I googled both #include"Adafruit_PM25AQI.h" and #include"bme68xLibrary.h" and downlo...

@inq Wow, number 4 looks like a great ancestor ! It seems to have a lot of potential for obstacle avoidance AND your future mapping bot (at least a...

@myoldlandy Welcome to the forum.

In the other post, I suggested (actual distance travelled)/(potential distance travelled). If you calculate the distance from [X0,Y0] (the cart center...

@inq I think the only difference is that I was suggesting calculating the absolute distance (i.e. the square root of the sum of squared differences...

@inq Would it be possible to substitute some expression of (actual distance travelled)/(potential distance travelled) instead of the difference in ...
