I bought some SG90s on eBay and none of them has a full 180° sweep. If that is any comfort. You may have more luck with more expensive servos!

I managed to find another document that has a much better explanation of Ex basics, including the differences between the USA & Canada, and Europe...

@garnold It is basically down to the question "how much current am I running through the transistor?". It sounds very much like you need a MOSFET ...

Further testing revealed that both square and triangle wave frequencies were quite accurate (less than 0.5%) but the sine wave frequency was off to ab...

@lesl A rough and ready solution may be to use 2 BME280s. One to collect the actual air pressure at ground level and pass this on to the second BME2...

@dronebot-workshop How about just buying the 2x2 and using a biscuit jointer (about $100) and plenty of wood glue! Just make sure you have enough ...

@byron I picked up the following benchmark sketch from Ralph Bacon's GitHub repository and was wondering if you would run it on the Teensy board and...

@byron I will have to look up the Teensy boards, thanks for the tip! In practice, you tend to stick with the stuff you already have in your worksh...

@byron My primary motivation for the above post was just to make those starting out with the ESP32 aware that FreeRTOS exists. I bought some ESP32...

@wolfgangw I have never used an ATTiny, but according to the pinout drawings, they are capable of both I2C and SPI. So I don't see any problems wi...

@WolfgangW You haven't specified how you wish to communicate between the µcontrollers. I2C or SPI or something else? I would not let the 16MHz to ...

@revver11 This might be a good place to start your search for C++ commands not specified in the Arduino Language Reference.

@wolfgangw Here is a link to my datasheet library. Feel free to download, it can be starting point for your own library.

@wolfgangw Here is the datasheet!

@wolfgangw Now you know what you can't do with a 75HC595, here is a possible solution! If you wish to read the values from multiple analogue senso...
