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
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. The MAX7219 controller manufactured by Maxim Integrated is a compact, serial input/output common-cathode display driver that could interface microcontrollers to 64 individual LEDs, 7-segment numeric LED displays of up to 8 digits, bar-graph … Read more
There was another “Microcontrollers, soldering and Tinusaur” workshop in our town of Veliko Tarnovo, a few days ago. On the first day, we assembled some boards, the second day we wrote some programs. For the younger kids, there were much simpler things to do – soldering blinking LED with 2 transistors, a few other components, and … Read more
