Wireless control of speakers
By using the micro:bit wirelessly to remotely control another micro:bit for the corresponding command execution, the micro:bit Retro Arcade can be used on this basis to wirelessly control the speaker via a joystick.
Voice controlled speakers
The definition of a "smart speaker" is a wireless audio and voice command device with an integrated virtual assistant that people can use through voice commands, such as asking the intelligent speaker to play music, announce the weather, set an alarm clock, etc. Some smart speakers can also integrate connectivity for Wi-Fi, Bluetooth, and other wireless protocol standards to add uses beyond audio playbacks, such as controlling smart home devices via voice. Some intelligent speakers also include a touchscreen. Smart speakers with touch screens are known as Smart Screens.
How micro:bit is precisely delayed and guaranteed?
One of the main problems encountered when using micro:bit is "How do I get my program to do more". For example, a program may want to display a certain amount of time on the screen but also respond to button presses during that time. Or, perhaps it needs to remember to do something at some point in the future, but continue to do its main function until then.
Adaption of micro:bit Retro Arcade with MicroCode
You can finish programming whenever and wherever without a computer, only with micro:bit V2, retro arcade, and MicroCode. Why don't you try it soon?
Wukong 2040 Case 2: Drive OLED Monitor
Wukong2040 expansion board is a new product developed by ELECFREAKS. Are you very interested in how to use it? The following is one of the cases of Wukong2040 expansion board: How to use Wukong2040 to drive OLED screen.
Create one API with CircuitPython and Wukong 2040 Breakout Board
Install thonny editor to use wukong 2040 extension to create an API. You can download the code related to Raspberry Pi pico on the website of citcuitpython for operation.
Case 6丨I2C (Integrated Circuit Bus)
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.
Case 8丨PIO (programmable input and output ports)
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.
Case 7丨SPI (Serial Peripheral Interface)
Today we introduce the last of the three brothers of communication, SPI.
Case 5丨What is UART?
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.
