Tutorial 003: Making Sounds with Buzzer

So far we’ve used a LED as output to produce light of different colors and intensity (Tutorial 001 and Tutorial 002) but we haven’t generated any sound yet. In fact, that isn’t very difficult to do. We will use a buzzer for output. According to Wikipedia … the buzzer or beeper is an audio signaling device, which may be mechanical, electromechanical, … Read more

OWOWOD – One Wire / One Way Output for Debugging the Tinusaur (Part 3)

It is time now to write a library that will use the Debugging Output. In the previous 2 articles about OWOWOD we managed to generate proper serial signal and start sending characters out observing  the result on an oscilloscope. (see previous articles Part 1 and Part 2 for reference) The functions we have so far are: … Read more

OWOWOD – One Wire / One Way Output for Debugging the Tinusaur (Part 2)

In my previous post “OWOWOD – One Wire / One Way Output for Debugging the Tinusaur (Part 1)” I wrote how to get a proper reference signal from a serial communication using USB-to-Serial TTL converter. The next steps are to generate the same signal but programmatically using the ATtiny85. And this is what I did … … Read more

OWOWOD – One Wire / One Way Output for Debugging the Tinusaur (Part 1)

I always wanted to be able to write something like this in my code … have that running on the micro-controller and see the debugging output on my computer.
