Attiny85 program IRremote

Projects General Guidance
1

Hello, I want to make a code for attiny85 with 6 buttons where button one is connected to PIN 1, button 2 is connected to PIN 2, buttons 3 and 4 are connected to PIN 3, buttons 5 and 6 are connected to PIN 4. Create a program so that you don't get confused when you make a mistake. one of buttons 3 and 4 or buttons 5 and 6 is pressed without confusion. When one of the buttons is pressed it will send a hex code to the remote where pin 0 is used for the IR LED to send the hex code. Where buttons 3 and 4 each have a 1k resistor connected in parallel, similarly buttons 5 and 6 each have a 1k resistor connected in parallel, button 1 has a 1k resistor and button 2 has a 1k resistor.

Can anyone help me?

What is the point to have a two buttons connected to the same pin?

That would help all of us...

because I have 6 buttons and 1 pin is used for the IR led, do you have any suggestions?

    }
}

is that correct?

I'm still confused when selecting the button so as not to send the wrong hex code

You can put even 60 buttons, but only four can be used

8

Do you understand that you can't use these buttons as a two independent buttons - the reading of both buttons always will be the same.

use another controller with the required number of pins

9

or if you really really need to do it with those 4 pins, you could set 4 buttons to trigger one pin each, and two buttons that trigger two pins when pressed.
like:
button1 pin1
button2 pin2
button3 pin3
button4 pin4
button 5 pin1and2
button6 pin3and4

so you have 6 logical inputs

10

thank you

11

with the same logic you can have your six buttons with only 3 pins, if extra free pin is desired...

12

ok thank you

13

What help do you want and for what?

14

Will adding a resistor to each button make a big difference?

15

resistor for what? pullup?

16

In order to use a two different buttons on a single pin - it doesn't help you

17

I suggested to do opposite :wink:
