Programming the Arduino is super simple when you have a finished sketch.

Quote from: poupou59890 on May 03, 2019, 12:07:17 pmFor the clutch, front break and rear brake (not clutch at this time I am waiting to check everything else before buying a complete set for the clutch) I use cheap chinese set of hydraulic lever on Aliexpress, than transducer (500 and 1000psi) in order to traanform the pressure apply to a signal between 0-5V. Here again, just plug everythign and that's it. https://www.aliexpress.com/item/Motobike-Racing-bike-lever-handle-bar-brake-pump-hydraulic-clutch-set-kit-17-5-piston-cylinder/32718100514.htmland for the pressure transducer : https://www.ebay.com/itm/Stainless-Steel-Pressure-transducer-sender-for-oil-fuel-air-water-100psi-2500psi-/172780141579

I use real motorbike shifter from China (same set than the rear brake with master cylinder and pressure transudcer), I think I will use 2 buttons and put a screw next to each one in order to be sure that it will be the screw to stop the foot peg and not the button to avoid breaking it.

Hope it can help.Even is the leabodnard is a bit pricey (around 60 euros) it is very easy to use, no driver, just plug eveything at the right place, put the usb and that's it.

Quote from: poupou59890 on May 09, 2019, 06:37:31 amI filled the brake fluid yesterday, and the feeling is good with the breka lever but I found that the range it is not as expected, not very linear...but I will try to adpat that later when the full rig will be built.Can't wait to see it running on VR
