When the footswitch isn't pressed, the input is always HIGH. When it's pressed, the input pin on the arduino goes LOW. huh? but that's not how dodgypete connected his board, is it? this one is from the scematic I posted yesterday. So, which scematic is right in your opinion, the last one i posted (...

BTW, I ordered some of the parts today. So I will be starting soldering soon. That would not be possible without your help, so thnx a lot!!!

Thnx Dodgypete! :thumbsup I think i have the final scematic right now :) mod.jpg would be great if someone could confirm that it's correct this way :lol: I'm a bit late on this one :lol: Your pull up resistors on the 2 inputs are wrong. You are correct in putting the resistors from the inputs to +5v...

You don't solder the transistors to that pad where it says R41/R42, you solder them directly on the encoder. Actually, I don't know what's the value of those resistors, but if they're not big you probably could solder. I don't know, just checking. Solder directly on the encoder, just in case. Hey D...

btw, feel free to edit the picture if you'd like to.

maybe next picture can help you with that..

woops, after reading your previous post, I realised I made a mistake with the connection of the transistor attachted to the green cable. so, now I understand that both pins (Emitter and Collector) have the same function since the transistor works like a switch here. But its not exactly clear where o...

Base of transistor for the preset switch comes from arduino. Emitter and Colector are both soldered directly to the terminals of the switch. One of them is in fact ground, but it doesn't matter which transistor pins connect where. The emitter pins of the other transistors are soldered to the middle...

ok guys,

I've made a little diagram about the mod. It's some kind of a summary of the information i got so far, with the questions i've got remaining included. It would be great if someone could check if its correct.
If so, im gonna start soldering Thnx!

Hey DWHB, Thnx for those answers, helped me out a lot further! Now got just a few remaining.. :) On the pictures you posted, I see three things at the end of the yellow, purple, and green wire. What are these small (half)cylinder-shaped things? they seem so be soldered between the r42connection and ...

@DodgyPete (or everyone else that would like to help me out), I was very suprised by the nice work you've done for this preset mod :applause: , so I decided to mod my hazarai as well :) But now I'm at a point where I have some questions that needs to be solved before I'm ready to start soldering. So...
