As a result, it sometimes does not work stably with potentiometers, and as already noted, the use of DAC is required. I will also note a slow and insecure reverse. But he definitely is:) If you 're a firmware author for stm32, I have a question: Is there any firmware for implementation of the three H-bridge for brushed dc motor throught one hoverboard mainboard?

I'm fairly sure the custom firmware he installed bypasses the one gyro input, because in Part 1 he just cuts the wires for that input.

hi, sorry for the slow reply, yes in part 1 it shows a bit better, you only need to use 1 sensor cable because that does both, the other is just for the leds and stuff

How do I bypass the 4 feet optical sensors for forward and back I got 2 separate controllers linked via 4 pin wire ....might try opto couplers

Hey, I'm curious what code you downloaded to the board before using arduino. Just with the two potentiometers? Also, what sources did you use for this?

hi, its the same code, just using the arduino allows you to offset the potentiometer values, there are lots of people who have put things online, blogs, projects, some of the github libraries have detailed records of their projects, hope this helps

Hi, nice video. I have a few questions: 1. How can I set it for reverse? like for go-cart. In your video the steering pot seems only control either one wheel and turn into a different speed and direction. What I want is actually simple, I want to steer it forward with the same speed, and I can also drive it reverse (with a switch or else). Can you tell me how can I do that? 2. Does the battery charging feature still work? 3. How fast the maximum speed can we set in the code? Thanks before.

hi, ok there are 2 pots, one does speed difference, the other does speed for both, so for reverse you just turn the speed one down further than when its stopped and it will go backwards and bleep, for example the 1024 pot value would be something like 0-300 = reverse - stop, 300 - 1024 = stop - full speed, do for your DAC if you are using one you need to split it like that if you are controlling forwards and reverse with 2 buttons / sticks. Apparently the battery charger does still work, however i am yet to test it. Max speed depends on what firmware you are using and if you change stuff in it, the fastest one i have tested myself is the bobbycar version, it has a speed setting you can set when starting up, i think with a 12s battery it can get upto 30mph, its a feature called field weakening, there is more info on this online if you google it, i just set it in the firmware to run off a 10s battery and its fast enough, maby 20mph. There is a guy who hosts an online firmware compiler that i have used a few times, you can edit the code online, compile it and download the .hex file to upload to the motherboard, here is his channel: kzread.info/dron/LUfNuoSML-vkLYiO0vBUHQ.html, hope this helps! thanks

Nice video. Can you upload the full arduino code ised for the Playstation controller? Also I'm curious if is possible to controll it from a raspberry pi with python. I plan to add a pan-tilt head to the rover I build. I control the PT head stepper motors with RPI, Slush Engine hat and a Playstation 4 controller. I also have an Android app and a web app to drive it. It will be nice If I can incorporate the hoverboard in the same set-up. I think it will make a great video. Thank you.

with the throttle it should come with a wiring diagram, they are basically a potentiometer with a lever on them

hi, do you mean to set a max speed? find this line of code: "dac2_value = map(set2, 120,0,1600,4095); //forwards" so the 4095 is the number for max speed, 1600 is stop, so any number between them two instead of the 4095 should reduce the max speed, hope this helps

So I think the throttle don't give full 3.3v at max load. i have to measure the max voltage of the throttle and adapt the code for my throttle. 4095 is 3.3v?

what happens if I leave the steering pot unplugged ?
