Is it a good one too? And, if I may ask, how is it compared to Adafruit?joan wrote:It's a popular kit.
I don't understand what you mean. Could you be more specific, please?joan wrote:it was originally targeted at Arduinos so you may have to allow for the Pi GPIO being 3V3 and the Pi not having any analogue GPIO (if not taken into account in the new kit).
Now I see. And what about Adafruit Kits?fruit-uk wrote:There are so many of these kits available.
A kit may be labelled as by a particular manufacturer but there is no guarantee that is what you will get. It may be a copy.
As mentioned, documentation is often poor, if at all, but even when supplied or found online may be wrong, pinouts etc. There is often no explanatory text at all. Legends on PCBs are sometimes incorrect too.
Having said that, they are all pretty basic sensors and if you are prepared to put a little work in researching what each does and deteremine correct pinouts and voltages they are a good starting point.
Joan's comment relates to the voltage that various sensors operate at.
If a sensor is designed to operate at 5V (typically OK forArduino) then it will need to be suppiled with 5V (generally) and any data output is also likely to be 5V
If you connect a 5V sensor output directly to a Pi you will kill your Pi!
You can connect a 5V sensor output to a Pi if you take suitable precautions. Search for level shifters or voltage dividers. There will be many suggestions available.
3|V or 3.3V sensors should be no problem.
Cool, thanks.fruit-uk wrote:I have no experience of them but would expect much better documentation - at a higher price, check forums and google.
As above posts, if designed for Arduino some sensors may be 5V or higher so be wary and take precautions.
Many kits sold for specifically a Pi may simply be the same as sold for Arduino - including 5V sensors.
They will work - as long as you take appropriate precautions
You may actually learn more from a cheap kit eg.
how to find and read/interpret datasheets,
how to use a multimeter and follow tracks on the small PCBs,
how to correct some of the sketches that may be supplied or modify them for use on a Pi.
Does Adafruit have a wide range of sensors?Douglas6 wrote:I'd recommend you get a few sensors from them
And what is the product's brand that you suggest, based on your experience?Douglas6 wrote:and later a big grab bag of cheaper parts from the web.
