1. Thanks, I’m a beginner but I’ll try to figure out how to make it 🙂

   • If so, have a nice adventure! I hope that materials I posted here will help you start your project.

2. Hey Lukasz, is attiny 13 powerful enough to make a sound reactive LED driver? I want to connect audio input on one pin and have LED on the other? Thanks 🙂

   • It’s depend on what do mean by “reactive”. ATtiny13 has ADC and hardware PWM. Should be enough to read audio and drive LED 🙂 Take a look at https://blog.podkalicki.com/a-few-funny-projects-using-my-simplified-implementation-of-dft/

3. Cesc z Litwy,

   czy bedzie pan Lukasz robic projekty z innymi AVR mikroprocesorami, na przyklad Atmega8 itd.?

   • Panie Tomaszu,
     czasami sięgam po ten mikroprocesor w swoich projektach komercyjnych. Część przykładów opublikowałem na GitHubie:
     – https://github.com/lpodkalicki/blog/tree/master/avr/atmega8
     – https://github.com/lpodkalicki/atlib/tree/master/examples/atmega8

4. Hi Łukasz, from what I understand attiny13a have 2 pwm channels so i wonder if you could help me to build pwm dimmer for 2 led fixtures by providing 2 channels which would run 2 Darlington transistors to run them?
   My understanding of pwm functionality of the chip is very limited. Thx ahead of time.

   • Hi, do you have any specific PWM parameters (frequency, duty cycle resolution) for your project?

     • For leds i don’t need more then 120hz but to be on the safe side it we can do more. Duty cycle resolution 8bit(max).

       Thanks again

5. Dear Sir,
   ATiny13 must be always be used with uno this will let the Atiny13 work as standalone unit? After of course compile it! Mfile winAVR!

   • Hi, do you mean Arduino UNO?

6. It seems like Atmel Studio 7’s display of Program memory use is not trustworthy. It does not show the same value as the hex-files properties does. There is a big difference.

7. This is a great blog. I like playing around with the Attiny MCU’s. Especially the 13. I have tried your software UART. It works great. In my last project, I use an attiny13 to get signals from a photoresister and a movement sensor. I use a ESP8266-01 to request measurements. My request terminated first with ‘>’. But i wanted to change this to ‘\r’. I use Atmel Studio 7 as IDE.
   When I use ‘>’ as terminater, everything is OK. But when I change it to anything else (‘\r’ or ‘A’), I get a program overflow.
   while ((c = uart_getc()) != ‘>’ && (p – buff) < 16)
   gives
   Program Memory Usage : 326 bytes 31,8 % Full

   while ((c = uart_getc()) != 'A' && (p – buff) < 16)
   gives
   Program Memory Usage : 2268 bytes 221,5 % Full (Memory Overflow)

   Do you have any idea, what causes this?

8. I really like your page! I am a fan of the ATTiny family as they are so much fun to work with. I will check back.

   • Thanks! 🙂

9. Hi Łukasz,

   I like the ATtiny13A too. Thank you very mutch for sharing your Soft UART library.

   For me the ATtiny is a perfect Co-Controller for the ESP8266 wifi chip and low current applications. You can power down the ESP, the ATtiny messures sensors, keep variable and uptime. After wakeup or trigger the ATtiny send it’s data to the ESP. The ATtiny itself going to sleep for small intervalls.

   Best regards, Robert

   • Hi Robret, you’re welcome! I’m glad you like it.

10. how to connect attiny13 with bluetooth module?

    • Hi, since ATtiny13 does not have hardware USART/UART you can try ‘talk’ to your BT module using Software USART. It should work, but note that errors rate will be quite high. Take a look at the article showing how to use software UART – http://blog.podkalicki.com/attiny13-software-uart-debug-logger/ . Please, let me know if it worked! 🙂
