* Compare the performance and development workflows for other architectures.

After reading some microcontrollers datasheets, I summarized the following differences:





  

             
    PIC16F877A
    ATmega328
    ATtiny44
    ATtiny45

 Individual assignments
 In this assignment I have to:
 * Read a microcontroller data sheet, program my board to do something, with as many different programming languages and programming environments
 as possible.
 In this assignment I have used Arduino UNO board as programmer. This link from Official website of Arduino produce a helpful tutorial about
 using Arduino as ISP.
 I tested my board that I designed and manufacture in week 7.
Arduino as ISP:
To use the Arduino UNO as an ISP, first step is upload an example with name "ArduinoISP" to the Arduino UNO boardr.

Wire Connection:
The connections between the ATTIny44 and the Arduino Uno is shown in the following table:

And the connection is described:

Uplaod the program:
After choosing ATtiny44 board and select the oscillator frequency from "Tools", upload the program using "Upload Using programmer"

Board test:
 I try a simple switch program:
