AVR architecture basics: on Wikipedia

Since I would like to use an Arduino, I searched around and found a good basic video on the architecture: ATmega328 Architecture Overview.

some transcripted notes from the video:

Going through Atmega Attiny328P Data Sheet i found important to keep the followinh notes:

Arduino as ISP

Arduino as ISP and Arduino Bootloaders

The programming process uses a VCC, GND and four data pins. Three pins connect MISO, MOSI and SCK between the programming micro and the target micro, thr fourth pin from the programming micro goes to the reset pin of the target.

...but at the MILL I could only find a Arduino clone: Freaduino UNO V.1.8.1. which seems to work the same way

made the connection between BlinkyBoard ISP Head to Freaduino ICSP head, which result in ERROR

averdude: Yikes! Invalid device signature.

Double check connections and try again, or use -F to override

this check.

Fortunately Timoteo was at MILL to help me, and after some deep analysis of the Arduino Board Schematic, proposed to connect the RESET pin directy to Pin13 of Arduino

downloaded the program from Adruino IDE and there was no more error's... !!!

to Test the board used the Arduino IDE example Brasic - Blinky, where I changed the Pin on the code

substitued the LED_BUILTIN with the pin number of my board, in this case pin 7, here is the final code that worked:

// the setup function runs once when you press reset or power the board

void setup() {

// initialize digital pin LED_BUILTIN as an output.

pinMode(7, OUTPUT);


// the loop function runs over and over again forever

void loop() {

digitalWrite(7, HIGH); // turn the LED on (HIGH is the voltage level)

delay(1000); // wait for a second

digitalWrite(7, LOW); // turn the LED off by making the voltage LOW

delay(1000); // wait for a second


Now making my own program to create interaction with the Tactile Witch

important info from by BlinkyBoard are:

using the actual connections I tried the EXample code for button provided by Arduino Tutorial Button

and it worked very well

Final code

Three simple button-LED c-programs illustrating the use of macros.

miss lots of simple steps... so continued to search...

Most important:



  • read a microcontroller data sheet
  • program your board to do something,
  • with as many different programming languages
  • and programming environments as possible
