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. The Problem Unfortunately that is not easy – in fact not possible with the standard tools used to work with the ATtiny85. The problem is this: (1) those … Read more
UPDATE 2022: The MAX7219LED8x8 library, now renamed to MAX7219tiny has now a new home at tinusaur.com/libraries/max7219tiny. Check also this MAX7219 & ATtiny85 tutorial to learn how the library works. I was playing with the MAX7219LED8x8 library and writing some code for how to use a simple scheduler to automate the task of outputting the buffer to the LED 8×8 matrix. … Read more

Check also this MAX7219 & ATtiny85 tutorial to learn how the library works. The MAX7219LED8x8 library uses now a simple scheduler to automate the task of outputting the buffer to the LED 8×8 matrix. This is not like a real task scheduler (in … Read more

Check also this MAX7219 & ATtiny85 tutorial to learn how the library works. MAX7219LED8x8 is a C library for working with the MAX7219 display driver to control 8×8 LED matrix. It is intended to be used with the Tinusaur board but should also work with any other … Read more
Ever wanted to do a project with that cheap DHT11 temperature/humidity sensor and did not want to go the Arduino way but with a simple ATtiny85? You probably know already about the issues with the existing Arduino based libraries running on the ATtiny microcontrollers, but can’t deal with them. TinuDHT is our answer to this. TinuDHT is a … Read more
This is a oscilloscope-like circuit for the Tinusaur, it is not a real oscilloscope but could be used as a base for one. It is built on top of the Tinusaur board (Atmel AVR ATiny85) and Nokia 3310/5110 LCD (PCD8544 controller). There is also simple preamplifier for the electret microphone connected to the ADC of … Read more
Here it is – the first Tinusaur powered robot. This is a vibrating robot that could turn left, right, and move forward. I decided to build that after watching a video on YouTube about the Kilobot project from Harvard University. Mine is much simpler and a lot less capable. But hey, that’s the first version … Read more
