DIY Logitech Pedals USB Adapter (No Soldering!)

[@DNACPR]

Brilliant Thanks, Upgraded to a T300 but wanted to keep my modified G27 pedals as a standalone set, I used a Pro Micro clone and the script uploaded flawlessly, pins were labelled the same except I used VCC instead of 5v it was giving out 4.5v (Raw was giving out 4.7v), Also I cut the pedal wires and soldered direct to the board as I didn't want the DB9 connector, for anyone interested in the pedals internal wire colours, Red:5v, Black:Ground, Green:Clutch:A0, White:Brake:A1, Orange:Throttle:A2.

Wanted to say thanks, I was able to run a Fanatec V1.5 Handbrake through USB without having to buy Fanatec's adapter. Thanks to your easy to follow video.

I've had a G27 shifter and pedal that was given to me because the owner's wheel stopped working. I just assumed the stick/pedals were useless without the wheel and stored it away for the past 8 years or so. Later on I got into microcontrollers, then a couple days ago I wondered if anyone got the stick/pedals to work with an Arduino and here I am. I couldn't believe it! Thanks so much

[@dave.madison]

That's amazing! I'm glad I was able to help.

[@seanjones4726]

Thank you so much for this. You saved me at least $70 pedals + shifter as I look to move away from the Logitech wheel.

[@cardz3607]

Made this two days ago and it works AMAZING!!! You deserve way more subs n views

Do you know if this mod works for the G27 pedals? Not sure if the G27 pedals are considered Driving Force pedals.

[@cardz3607]

@@GodzUnit01 I can confirm, it does

[@Factsfun-kg4xc]

This is perfect for my homemade FFBeast direct drive wheel! It'll do the job until my CLS pedals arrive, though they might take a while since they're on backorder.

[@zakker365]

Thanks mate, now I can use my g29 pedals with my moza r12 without the need to have the whole g29 connected.

Wow so easy! I loved the video, the way you explain, amazing video. Also nice socks I have those too.

[@XxBoxerman74xX]

Did you have to modify the code to get it to work? What pins did you use?

[@MiguelAbd]

Man, this video is 10/10. Thank you so much!

[@cakeeaterpro]

Wow, fantastic tutorial, fantastic design and you got a subscriber and a like before I even got to the end of the video! Honestly, this was so well done in all aspects....I can not come up words that can articulate just how impressive it was. Even in it's simplicity! One question: Will this work with the load cell kit installed on my G923 pedals? My g923 needs a to be replaced by Logitech so I am w/o that for ~2-4 weeks. I have my old GT Driving Force wheel which will be fine....I guess as a stand in until I get the replacement but I can not go back to the GTDF pedals.......no way no how. If I can get the G923 pedals connected as stand alones I could make it work in the short term.

[@dave.madison]

Glad you liked it! As far as I know the G923 pedals are functionally identical to the G920 pedals, so if the load cell kit works on your G923 I'd imagine it would work with this. Let me know if you give it a try!

[@MotmoRacing]

ever got it to work? my g29 brakes are modded with axcsim truebrake and it works just fine :)

[@potatoMethod]

just did this and works like a charm with some small caveats. i will only point out that, it is better to follow the squematic of the db9 serial port because most ports have ground on pin 5, not pin 1 (as is the standard with the db9 port). also, following this guide, there is a chance that you will end up with reversed clutch and acceleration pedals, just swap places of the a0 and a2 cables on the arduino and you should be fine. IN THEORY it should be possible to have both the shifter and the pedals in a single arduino leonardo depending on the amount of data connections the shifter needs (IIRC is 3) BUT it would require a complete rewrite of the code and to solder 4 cables into 2. without both of those things is not possible.

[@dave.madison]

Hi! I'm glad this worked for you and I appreciate the feedback. As far as I know connecting ground to pin 5 will not work with these pedals, as it's not connected internally. You can find my pinout notes from disassembling my own pedals in the library documentation here: dmadison.github.io/Sim-Racing-Arduino/docs/logitech_pedals.html If using pin 5 as ground does work for you then your pedal unit may be wired differently. Pin 6 will work as ground but has the potential to create a dead short if a 2-pedal unit is connected instead.

[@arr1009]

Thanks a lot for share it! Works great! Could be possible to make a general solution for pedals and shifter using just one Leonardo board?

[@edvansilvagamer]

Perfect, can this configuration be used to change the G27 gearbox too?

[@jeffgamer1979]

Hello Dave Madison! Thank you for sharing this excellent experience, but I would like to know if it is possible to add the steering wheel in addition to the pedals, even without the feedback motors? I have a Logitech G920 with a defective board, and I would like to take advantage of it, is it possible?

[@rasaskitchen]

I wonder if I could use a similar adapter to wire up my HORI pedals. I was thinking I could use it as a mute/unmute button for zoom. The HORI connector looks like a RJ11 connector. Thanks for posting this, it inspired me to look into this.

[@nicolasgambalonga6467]

Hello Dave, thank you for this project. I have a problem, the calibration does not work while the pedalprint works correctly. Have you already found this problem? Thanks in advance Nicolas

hello, thanks a lot for the tutorial, is the pinout for the pro micro the same

[@hchc111]

Hello Dave, thank you for this video, very easy to follow even for novice. I have a question, I’ve noticed in another similar video they also use an extra wire to connect another 5v (pin 6 & 9)? Can you explain to me what the difference is?

[@dave.madison]

Pins 6 and 9 are connected internally on the 3-pedal unit. It isn't necessary to connect them on the adapter, it will function the same way.

[@kotai12]

Can you do this with a Arduino Pro Mini ?

[@metcout]

Hi, thanks for this video, i'm looking to do this for nephew, is it possible to combine pedal and shifter into one board ? I know the code will need some adjustement but did you tried it ? Thanks

[@dave.madison]

Hello! It is absolutely possible to combine both into one board. The example codes need to be combined (mostly copy + paste) and the analog shifter pins need to be moved to A4 / A5. But it should be very straightforward.

[@metcout]

[@Ronkeldonk]

How much does the parts do make all this cost? I have no idea about electronics

[@mateuszwargacki3010]

What are the consequences? Questions are felt because I have some products, I bought an adapter and when I press the pedals, I see that the reaction is delayed.

The library can already do that, you just need to combine the shifter and pedal examples.

[@alexiscool4438]

Hi, is it possible to solder the connectors straight to the board

[@dave.madison]

Not to the Leonardo, or at least not well. If you want to solder the connections I would suggest buying a Pro Micro board instead.

[@NightfoxSD619]

After programming would this work on Xbox?

[@NotItzIshan]

I was wondering what was the purpose of the adaptor? (No offense, great job!)

[@dave.madison]

It converts the raw signals from the pedals into a USB joystick that can be used with games or racing sims. Typically you would connect the pedals to a Logitech wheel that would do this for you, but this lets you use the pedals on their own without a matching wheel.

[@NotItzIshan]

@@dave.madison Genius! We will need the logitech pedals though, right?

[@Ronkeldonk]

​@@NotItzIshanyes you will need logitech pedals to use logitech pedals 🤔😅

Hi do I have to buy the db9 connector can I just cut the plug of the pedal and connect it straight to the arduino in stead of buying the db9 connector.

Remove the cable from DFGT pedal and use it to replace the wire on the G2x pedal. There are instruction out there. No need to make any adapter. Cost is 0. No clutch of course. Remove G2x wire always from the bottom use a cardboard box as support.

[@Lautaro02219]

Hello, how are you, is the script compatible with the ATmega328 microcontroller?

No. The 328P does not have a USB interface. It can read the data from the pedals, but it cannot output it to a PC as a joystick.

Just buy the adapter bro lol By the time you buy everything needed in the video you could have just bought the adaptor lol

[@dave.madison]

At the time I made this video the official Logitech adapter didn't exist. The DB9 connector and the microcontroller are the only essentials. Most people have a pair of pliers and can scrounge up some wire. With the current prices linked in the description, this method costs roughly half the price of the adapter. Something to consider :)

[@jojodosjogos]

True, not only its half the costs, but there's also the matter of paying import taxes for some, such as me. Whereas DIY products can easily be found for very low cost where I live in comparison to bringing the adapter overseas.

[@dave.madison]

Hi Dorian. I have indeed encountered that problem, but thankfully there's an easy solution. When calibrating the pedal in Windows, don't move it all the way back to the start for the 'minimum' reading. That will give you a bit of a buffer so it doesn't always send data at rest. There is also a built-in calibration function in the library that can be accessed using the PedalsPrint example. You can use that to calibrate the code to your specific pedals, which should also solve the problem. I hope that helps.
