Electronic Basics #3: Programming an Attiny+Homemade Arduino Shield

If you are using only a couple of pins of the arduino for your current project, you might be able to shrink the IC. I am going to show you an easy way to use an Attiny instead of an Atmega328.

I'm hooked on your electronics basics videos because they're so high quality

Just finished assembling my ATTiny programming shield. This works really well. Thanks!

Your channel is the best channel anyone could find for DIY you from bottom of my heart :)

Great tutorial! Finally made my ATTiny85 work, but this video is a bit outdated.
For anyone struggling, check out the latest High-Low Tech tutorial, the latest version of arduino (1.6.7 at this time) works fine for programming.

Your video quality has improved now I'm looking back upon your older videos. Keep up the good work!

Thank you, based on your video now I can use USBASP and USBTinyISP also for programming my Tiny84, Tiny85, and Tiny13

I'm interested in home automation and off grid projects. I enjoy your videos and see a lot of potential. Perhaps you could show some power generation from Peltier...

"Yo dawg, I heard you like programming, so I program an ATTiny with an Arduino, which itself already had a programmer within, so you can program while you program"

You have some great videos, keep that good work up!

[MaciekStaniec]

It worked after a year of fails. Thank you very much. ;)

Bit banging is not as you describe it "protocol emulation", this is a misdescription. Bit banging is the ability to shift or add bits onto an output address or variable, usually for the purpose of crafting specifc values of IO.

0:32 I think that the arduino ur holding is a counterfit. The deep blue pcb, the wierd usb and resistor next to it is a good sighn.

Adding the status LEDs 7/8/9 from the Sketch is easy and helpful!

Thanks for this very clear video. I found the same procedure in a couple of projects at arduino.cc and hackaday, but your explanation and photography are the best. I tried it with a fresh Attiny85 and a generic Uno clone (with the CH341 USB to serial chip), and got the dreaded "Invalid device signature (I'm running the Arduino IDE 1.8.13, installed from arduino-1.8.13-linux64.tar.xz on Debian 10, in case that matters.) The connections are correct and Vcc is 5.01V at the target. The forums tell me this means my ATtiny85 has its clock mode fuses set wrongly, and I need to use the high voltage programming mode to "unbrick" it. Which is not a function ArduinoISP can perform, and it's not how the data sheet says the chip ships. So I have a few questions. 1. Have you run into this issue? Did applying an external clock fix it, or did you need to use the HVP? 2. Is there anything in ArduinoISP that requires a genuine Uno? or should any generic Arduino work? 3. What's really going on with that 10 uF capacitor on the Arduino's RESET\ signal?, it seems like a kludge.

I love those tiny micros - Built a custom UNO shield just for this that supports all tiny micros with some dedicated test sockets too. you can find it on tindie - Just type 'All ATtiny Arduino programmer shield'

Stick away from this tutorial when it comes to the libraries, there are other ways to get them, plus the files he mentions in the video have changed

[djtoddles]

0:51 That does seem legit, in fact there's enough room to fit 2 or 3 more of them, should I try that?

I can't believe i'm watching tutorial 3 and still have no idea what is going on. I'm waiting for you to say something i understand, which is not happening yet - like, 'christmas lights' and i smile and say 'yes, carry on'

[boehml]

Well done! I prefer mcrochip PIC µC's but that's a matter of taste.I really like the professionalism of your videos, keep on the good work.
