I wonder about things.
Alerto! is a portable and connected Motion Alert Device that you can use to detect motion remotely. Get a notification on your phone or an SMS, whenever motion is detected. The device uses KEMET's SS-430L-N PIR motion sensor.

Hey guys. Multiple contests are being run at Hackster.io where you can get FREE HARDWARE and thousands of dollars 
in prizes if you win. So make up some ideas and give them a try.
Please note that not submitting projects after receiving free hardware can affect your reputation and may disqualify you for future contests.
@rafitc99 The member variables of a class can not be accessed without an accompanying object; that's the concept of a class. If you want to return three values, simply update the member variables AcX, Ac and AcZ, and access them as,
Serial.println(goo.AcX);
Serial.println(goo.AcY);
Serial.println(goo.AcZ);
@zainmuhammed RP2040 is not a perfect MCU nor it was designed to become one. It's still an ARM Cortex MCU. You can see many other similarly or even lower priced offerings from other manufacturers. For example, look at ESP8266 and ESP32. They don't use ARM core and thus save a lot on IP royalties (Intellectual Property for Silicon designs) and come with even more features.
But since it's from the house of Raspberry Pi, everybody knows that RP2040 is going to reach everywhere like wildfire. That kind of volume projection allowed them to cut the cost in the early stage of release. Because, cost of producing something totally depends on the scale of manufacturing.
Since RPi is from UK they must have also been able to make a better deal with ARM, which is also from UK.
When you want to create an object of a class and it doesn't take in any parameters, then
Gy521 goo; //object declaration
is enough. Then invoke the initialization function,
goo.begin(); //initialization
For that, you need to create an initialization function. You can copy the statements in your constructor there.
@salmanfaris Yeah, just like features and price, long term support is also crucial in determining the efficacy of a microcontroller. What RPi has done with the new introduction of the MCU is close to perfection. Like you said, they had everything ready before the release and that how it should be. No other manufacturer has ever done this before. RPi understands their users and what they seek, as always. With that, they have been able to pull something off that no other manufacturer could.
RP2040 is not just going to be used in hobby spectrum, but also high volume commercial applications. And that's why I said before it is setting off a REVOLUTION. It's just a matter of time RP2040 supersedes ATmega328 in popularity. Microchip has to worry again! ðŸ¤
