Arduino – blinky with Timer1 COMPA

Next Arduino blinky project. This version of “blinky” example is using Timer1 Compare Match A interrupt to make an onboard LED blink for roughly one second. The code is on Github, click here. Parts Required Arduino board (i.e. UNO) Software This code is written in C++ and can be compiled using an Arduino IDE. All information about how to compile this … Read more

Arduino – blinky with Timer1 OVF

Yet another Arduino blinky project. This version of “blinky” example is using Timer1 Overflow interrupt to make an onboard LED blink for roughly one second. The code is on Github, click here. Parts Required Arduino board (i.e. UNO) Software This code is written in C++ and can be compiled using an Arduino IDE. All information about how to compile this project is here. /** * … Read more

Arduino – blinky with delay function

This is another blinky project. A “Hello World” program for the electronics. This version of “blinky” example is using delay function to make an onboard LED blink for roughly one second. The code is on Github, click here. Parts Required Arduino board (i.e. UNO) Software This code is written in C++ and can be compiled using an Arduino IDE. All information … Read more

ATtiny13 – controlling LEDs WS2811/WS2812

There was a time when controlling RGB LEDs was not always an easy task. I this article I would like to show how to make it without difficulty using one ATtiny13 and LEDs based on WS2811/WS2811 driver. The addressable LEDs are using protocol similiar to OneWire (very time-depended protocol) and can be connected together to create a strip … Read more

ATtiny13 – blinky with timer OVF (assembler version)

Another blinky project in assembler. That one is based on Timer Overflow interrupt. In our circuit a LED is connected to PB0 and is blinking for roughly every 0.5 of second. The code is on Github, click here. Parts List ATtiny13  – i.e. MBAVR-1 development board Resistor – 220Ω, see LED Resistor Calculator LED Circuit Diagram Software This code is written in … Read more

ATtiny13 – blinky with timer COMPA (assembler version)

In this example I’would like to show you how to write in assembler “blinky” project that uses timer COMPA (Timer/Counter Compare Match A) interrupt. The previous blinky project is very similar to what is presented here, but with one exception – the delay section has been replaced by timer interrupt.  In our circuit LED is connected to PB0 and is blinking … Read more

ATtiny13 – TM1638 Library

This is tinyAVR (ATtiny13, ATtiny25, ATtiny45, ATtiny85, and other) library for LED controller modules based on TM1638 chip. Modules based on TM1638 provide three signal connections (CLK, STB and DIO) and two power connections (VCC and GND). Signal pins can be connected to any pair of digital pins of the AVR chip. Signal pins configuration is … Read more

ATtiny13 – running dots & digits on 7-segment LED tube display

This article shows how to make an example project of “running dots & digits” using ATtiny13 and popular 7-segment LED tube display based on MAX7219/MAX7221. Complete code is on GitHub. MAX7219/MAX7221 library for LED tube display A lightweight library for 7-segments LED tube displays based on MAX7219/MAX7221 chip that works with tinyAVR family (ATtiny13, ATtiny25, ATtiny45, … Read more

ATtiny13 – TM1637 Library

This article is about tinyAVR (ATtiny13, ATtiny25, ATtiny45, ATtiny85) library for 7-segment display modules based on TM1637 chip. These TM1637 modules provide two signal connections (CLK and DIO) and two power connections (VCC and GND). Signal pins can be connected to any pair of digital pins of the AVR chip. Signal pins configuration is defined … Read more
