+## **What I did this week**
-## Code Example
+- use and compare the performance of microbit, Arduino Pico and Seeeduino Xiao →in this page
+- browse the datasheet of ATtiny3216 I used → [Individual Assignment](https://fabacademy.org/2022/labs/kannai/students/yukiya-yamane/assignments/week09/)
+- write some programs to control illuminating LEDs by using my programmer→[Individual Assignment](https://fabacademy.org/2022/labs/kannai/students/yukiya-yamane/assignments/week09/)
-Use the three backticks to separate code.
+## **Trial 1 : microbit**
-```
-// the setup function runs once when you press reset or power the board
-void setup() {
- // initialize digital pin LED_BUILTIN as an output.
- pinMode(LED_BUILTIN, OUTPUT);
-}
+### what is microbit
-// the loop function runs over and over again forever
-void loop() {
- digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
- delay(1000); // wait for a second
- digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
- delay(1000); // wait for a second
-}
-```
+is a pocket-sized computer that introduces you to how software and hardware work together. It has an LED light display, buttons, sensors and many input/output features.

+- Access to Microbit [editor](https://makecode.microbit.org/?lang=en#editor)
+- edit the function on the visual programming
+ - when pressing “A†bottun, illuminate the LED of (0,0)
+- edit the code in the visual programming
+
+
+
+- Click download and drag&drop to “microbitâ€
+- build done
+
+ 
+
+
+### Trial 1-2 : taking advantage of display and accelerometer
+
+- edit the function on the visual programming
+ - when pressing “A†bottun, illuminate the LED in the shape of “â¤ï¸â€
+ - when shaking the board, show striking “Hello!â€
+ - when pressing “B†bottun, clear screen
+
+ 
+
+
+- done
+
+
+
+
+
+### Trial 1-3 : combitation to the peripherals of loudspeaker
+
+- edit the function on the visual programming
+ - when pressing “A†bottun, show icon of “â¤ï¸â€ and play melody
+
+
+
+- done
+
+### Trial 1-4: switch between Blocks and programming language(Javascript or python)
+
+
+
+### The feeling to use
+
+- Designed so that even elementary school students can understand it, making it very easy and fun,
+- It is very easy to use that the connector is initialized by simply plugging it in again.
+- By switching programming languages, it is possible to determine which functions are realized in what kind of code and how they are implemented.
+
+## **Trial2 : Arduino Pico**
+
+### what is Arduino Pico
+
+Arduino-Pico is a community port of the RP2040 (Raspberry Pi Pico processor) to the Arduino ecosystem, intended to make it easier and more fun to use and program the Raspberry Pi Pico / RP2040 based boards.
+
+### the Arduino Pico I used
+
+- IC : **RP2040 by ARM**
+- Dual ARM Cortex-M0+ @ 133MHz
+- 264kB on-chip SRAM in six independent banks
+- Support for up to 16MB of off-chip Flash memory via dedicated QSPI bus
+- DMA controller
+- Fully-connected AHB crossbar
+- Interpolator and integer divider peripherals
+- On-chip programmable LDO to generate core voltage
+- 2 on-chip PLLs to generate USB and core clocks
+- 30 GPIO pins, 4 of which can be used as analogue inputs

+- when clicking “Startâ€, the program is written to the board,
+- done
+
+movie
+
+
+
+[reference](https://osoyoo.com/2021/07/24/pico-graphic-programming-lesson-1-set-up-pico-make-it-blink/)
+
+### The feeling to use
+
+- It is very easy to write and run the program by pressing the bottun of “startâ€.
+- Less sophisticated UI than Microbit, but more scalable as it is connected to a bullet board.
+
+## **Trial 3 : Seeeduino Xiao**
+
+### What is Seeeduino Xiao
+
+The Seeeduino XIAO is the smallest member of the Seeeduino family. It carries the powerful ATSAMD21G18A-MU which is a low-power microcontrollers.
+
+
+
+### The Seeeduino Xiao I used
+
+- IC: Atmel SAMD21 by ARM
+- Powerful CPU: ARM® Cortex®-M0+ 32bit 48MHz microcontroller(SAMD21G18) with 256KB Flash,32KB SRAM.
+- Flexible compatibility: Compatible with Arduino IDE.
+- Easy project operation: Breadboard-friendly.
+- Small size: As small as a thumb(20x17.5mm) for wearable devices and small projects.
+- Multiple development interfaces: 11 digital/analog pins, 10 PWM Pins, 1 DAC output, 1 SWD Bonding pad interface, 1 I2C interface, 1 UART interface, 1 SPI interface.
+
