[@eidolon0]

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 Finally made my ATTiny85 work, but this video is a bit outdated.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.

hello yesterday i bought an at tiny 85 and before 5 minutes it worked fine but the last time i plugged it in i put reverse voltage by mistake and now it doesnt run did i burn it?

[@JFrap]

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.

[@etiennegagnon5479]

+GreatScott! Why don't you burn the boot loader to the atttiny to run it at 8mhz instead of 1mhz?

[@WhiskyPankcake]

What is the capacitor between reset and ground for?

[@peeenoytv1149]

The time constant of the capacitor will help programming the uC

[@ddee2501]

It is there to stop the Arduino re programming itself !

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...

I'm very happy for the video. Now I'm working with a arduino project where needed 3 I/O pin and 1 is digital pin-2 for interrupt. Could I use the tinny arduino for the interrupt functionality?

[@MRTz_music]

can you give me a specific artiel number of the attiny85 becaus i didnt f8nd the right one

[@Afif87123]

Ahh, memories

[@kaylanipimp1]

In order for using the Arduino the old way after using it for programming the Attiny should I just go on Tools/Programmer and select ArduinoISP instead of Arduino as ISP or do I need to burn the Bootloader again?

[@Ahmed.Al-Hloul97]

Mr GreatScott! Why should I put a 10 microFarad capacitor between the reset pin and the ground pin? And if I didn't use the capacitor , what would happen ? And is it necessary that the capacitor's value is 10 microFarad ?

[@JimisekMichalas]

ahmed alhloul you put it there so arduino wont reset :) at least its how I understood that.

[@Loundre3]

To filter out high frequency noise, so the Arduino doesn't reset randomly.

[@hongbohe4454]

In my opinion, Arduino IDE will send reset signal once you hit "Upload" button, despite the Uno on the other side of USB cable is running "Arduino ISP" sketch and actually not the target you want to upload your program into. Your Uno will be reset and broke the uploading operation. By hooking reset-pin of Uno with capacitor your Uno will continue working and "Arduino ISP" sketch will handle your program to ATtiny. If you Upload with "Uploading using programmer"(option-click Upload button or alt-click for a PC) sometimes you won't need a capacitor. It will treat your Uno as an ISP and tries to reset the target chip instead of Uno itself. But in recent versions(1.8.7) broke this feature and Uno will still be reset. It is because a protocol change and Uno will still treat this signal as reset. see this for detail github.com/arduino/Arduino/issues/8293

[@guillaume8437]

Hi! Could you please tell where you got this RGB LED ribbon thing?

I'm getting into the ATTiny85 myself. I bought a programmer for it but it didn't work. I'm not sure which way around the capacitor should go on the Uno.

А возможно ли для Attiny85 скейч для управления Servomotor сделать? Я пытаюсь, но у меня не получается. По этому поводу в интернете почти ни какой информации нет. Как я понял из интернета: с ардуино платформой это сделать не возможно, так как там с 16 бит, а тинка работает только до 8 бит.

[@Jajaho2]

Hey Scott, I think you mixed up the ground and the reset pin when you showed the attiny on the breadboard (alone). Please correct me if I m wrong.

[@thedavinator37]

If I’m using the A0 and pins 7-12, where could I get an attiny that accompanies all of that?

[@douglasheld]

03:15 Why is the capacitor needed?

[@alexandrumoise1511]

why do you put the capacitor?

[@Tyson888]

To protect from over voltage

[@alexandrumoise1511]

Thank you

[@ericcartmann]

caps dont protect from overvoltage. when you short a cap to ground you make a low pass filter. the higher the capacitance the more higher frequencies are killed. A capacitor of infinite capacitance only allows DC to flow. The cap is so that random EMR or voltage dips etc etc dont end up tripping the reset pin when the reset pin is not supposed to be tripped. This can brick the chip, since programmers use reset for programming the chip.

[@alexandrumoise1511]

***** oh, OK, that makes a lot of sense. Thanks

[@SirDella]

[@vedant6633]

Why there is no need of clock in attiny ....I mean any oscillator .....becuz how will the ic know the timmings like delay(500);??is there any inbuilt oscillator

[@RandomMusingsOfLowMelanin]

I saw the pinout of ATTiny an dit does have SPI pins. How should I use them?

[@jamcguire100]

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.

[@Rafrial]

Thanks, it works. But how to RESET the program in ATTiny to the default?

[@RobinGlauser]

Can you reverse the order of the electronic basic playlist? KZbin plays first number 20 and so you can't watch them in one go.

[@morphman86]

So you can remove the programmable part of the Arduino and install directly in another circuit? I did not know that. Arduino gets cooler everytime I see it. I take it the programmable IC is slightly cheaper than the entire board, so you could get those in bulk, right?

[@JustFun-wp3mm]

The programmable ic is a lot cheaper than the board, but, will need some other, cheap components. For best operation, the atmega needs a crystal, a couple of ceramic caps and, if powering from battery, a voltage regulator. These can be purchased as a set on eBay.

[@anujamerwade3179]

Will you please help me regarding where can I download your multiplex arduino code from?

[@drdischord]

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 0x000000". (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.

[@drdischord]

I'm digging into question 3. It seems the Arduino IDE talks to the serial port the wrong way, causing a pulse on the Uno's RESET\ when it's not done talking to the ArduinoISP running on the Uno. It leaves dealing with the (emulated on USB) serial port to the avrdude program, and avrdude doesn't know enough to do it right. So the 10 uF cap is a kludge working around a missing feature in the avrdude program. For a less kludgy fix, avrdude needs a new command line option to tell it not to pulse that serial port status line, but leave it connected all the time. And Arduino IDE needs to know how to set the "serial port" up so that avrdude doesn't have to do it, and when to use avrdude that way. Or avrdude needs to get way smarter about when to open and close the emulated serial port. No wonder everybody kludged it with a 10 uF cap instead.

[@drdischord]

I tracked my problem down to an intermittent short between MISO and SCK. They were shorted when the shield was in place and open when I pulled it off the Uno to buzz it out. The SCK is low when the Arduino-as-ISP samples MISO so it was always reading back zeroes. Thanks again for these excellent videos!

Hey GreatScott! I made this for the Attiny 85 and 84 and used my nano instead of the uno. Couldn't have done it without you. I wanted to show you pictures but I don't know what the best way is to share them with you. My only issue was soldering the female header pins on the boards to connect the Arduino. It was hard to get the soldering tip and solder under the plastic pins to make the connection to the strip board. Suggestions?

[@troypuchini9092]

+Hydrameda the issue was actually soldering the headers on. because they go on the bottom of the board (where the solder strips are attached,) I couldn't get my soldering iron between the header and soldering strip. I'll try to get a picture

[@troypuchini9092]

www.instructables.com/id/Soldering-a-LED-To-The-Wrong-Side-Of-A-PCB/ This is an example of what im talking about. Except they are talking about a LED, but same basic issue.

[@Fleurlean4]

+Troy Puchini Those header pins have the black plastic spacer that can usually be moved/removed. You could solder the longer side of the header pins to the copper side of perfboard, then when soldered just wiggle the plastic spacer down or take it out completely. I found I can't really trust hookup wires to stay connected if headers have that plastic Part

[@TheHowToGuy995]

You are the one of the few that can solve this mystery. I uploaded a sketch to my attiny85 that outputs PWM according to a potentiometer. It didn't work. It drew about 2.8-3.5mA, but when I unpluged the ground to the attiny, it started working and only drew around 0.7-2.5mA. Why is this? And why will it not work when ground is connected to the attiny?

[@RandomLOLGamer]

It is hard to know what is the problem if you dont list every connection here. Probably the potentiometer keeps sucking current - use higher ohm value pot. Protip - Make your sketch work on an arduino uno or nano, and use Serial.println(value); to debug the code.
