Wow, it's another festive year - the Year of the Rabbit! According to the ancient Chinese zodiac, the rabbit is a symbol of resourcefulness and good fortune, and the Year of the Rabbit will be an unusually busy but peaceful and calm year. In Western culture, the rabbit has also always been a symbol of good fortune. The rabbit also often plays intelligent and sympathetic characters, such as Mr White Rabbit in Alice in Wonderland and Peter Rabbit in Peter Rabbit!

All in all, people place good hopes on rabbits and they evoke wonderful associations. This is why rabbits have a symbolic meaning of goodness, beauty and peace.

I've used most graphical hardware programming platforms, probably more products than most product managers in this field.

That's not something to brag about, it just means I've wasted more time than anyone else on a myriad of programming platforms, and it means I've been slow to come across a really good product.

Unfortunately, as a rule, this is what computer education is all about. Learners spend many hours learning nothing but the bad ideas of the system designers.

Fortunately, John Maloney brought light to the field and ended my life of bouncing around from platform to platform.

The laser engraver we are familiar with will only appear in some large factories or workshops, and people cannot use it in their underground warehouses or homes. When the global epidemic is severe, people have no way to go out for activities and can only spend time at home. Therefore, all kinds of exquisite small gifts, or furniture, accessories, etc., have been made.

So naturally, the tools to make these things are also selling well. Therefore, a low-power version of the laser engraver suitable for home use was born.

The Wannian Calendar is one of the oldest solar calendars in ancient Chinese lore. It is named after a man named Wannian who compiled the calendar during the Shang Dynasty, and in honour of his achievements the calendar was named the Wannian Calendar. As Christmas is approaching, we have created a Christmas version of the almanac, combining Chinese and Western cultures, for those who need it.

We made a weightlifting robot this time. When the robot hears us applauding, it will lift the barbell on its chest with force, then hold it for three seconds with a smile and then put it down. If our applause keeps on coming, then the weightlifting robot will make a continuous movement to lift the barbell and be very happy, it even comes with an encouraging sound effect, which is great!

Let's combine micro:bit board, an unused Android phone, and ELECFREAKS micro:bit Nezha 48 IN 1 Inventor's Kit to create a car that can be remotely controlled via WiFi and observe the car's surroundings in real-time via the camera. In this case, we will use two applications, the eWeLink APP and the eWeLink camera APP.

The I2C integrated circuit bus, a serial communication bus using a multi-master-slave architecture, was developed by Philips in the 1980s to allow motherboards and embedded systems to connect low-speed peripherals.

The correct pronunciation is "I square C" or "I square C", while "I two C" is the wrong pronunciation.

PIO is a special peripheral of RP2040, let's learn more about it today because there are more contents of PIO, so this issue has more contents.

Today we introduce the last of the three brothers of communication, SPI.

In the last -term we have used ADCs and internal temperature sensors to read pin voltages and on-chip temperatures to implement the process of converting analog signals into digital signals. By now, having learned to use PWM and ADC, these set the stage for our Pico:ed to work in different situations.
