What’s our goal? To connect a MAX7219 based LED Matrix module to an ATtiny85 microcontroller and control the LEDs. Doesn’t sound very complicated, right? The Titorial We wrote a short tutorial about how MAX7219 modules work, how to connect them to ATtiny85, and how to write a simple library to work with them Continue reading the MAX7219 ATtiny85 tutorial here. Please, leave … Read more
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
This is quick update for September and October. The presentation at Maker Faire in New York (http://makerfaire.com/new-york-2014/) on Sept. 21st went very well – 80% full of the small auditorium. The Faire itself was terrific. On October 15, as part of the European CodeWeek (http://codeweek.eu/) the Tinusaur Project was presented to the students and teachers at one … Read more
Another beginners tutorial is on the way – this time about a fading in and out LED. This is simple tutorial that shows how to connect a LED to the ATtiny85 based Tinusaur board and write a program that makes the LED to fade in and out using PWM (pulse-width-modulation) technique. Note: The code in this tutorial does not use the … Read more
Our first tutorial Tutorial 001: Blinking LED (that’s the older one) was just updated and put under the Tutorials menu. This is very simple tutorial that shows how to connect a LED to the Tinusaur board and write the “Hello World” of the microcontrollers – very simple program that makes a LED to blink. Since the Tinusaur … Read more
UPDATE: New version of this tutorial is available on the Tutorial 001: Blinking LED x1 page. This is a very simple tutorial on how to make a LED blinking. Since the Tinusaur board is a very standard ATtiny breakout board this could be applied to almost any such other board. The code was tested to work with … Read more
