YOU ARE GREAT!!!!!!! THANKS A LOT

[@refab2262]

Glad it helped!

[@AznivPetrosyan-oz7lo]

Thank You Very Much. You helped me a lot. Great job

Glad it helped!

OHHHH THIS IS GREAT!
Thank you so much!!!
Does the motor module happily work off the 3.3v of the ESP 32?
I also love the playstation controller as input, that's fantastic!

[@refab2262]

I've ran it on the bench/desk running off the 3.3v. My controller has a voltage regulator, so usually split the output from the power (5-6v) supply.

Hello Mike,
Many thanks for this tuto.
I am alas in trouble whith an unexpected issue... could you explain me something ?
first of all say that I already drive two of this BTS, wired as the same to your "method 1" and without problem through an Arduino (Nano). So, my BTS are already soldered, pins 3,4,7 together (the BTS 5V then)
In order to add an OTA function, I was working on migrating my code toward an ESP. On a breadboard, with motors simulated by leds, no problem at all. But at the end, in "my real life", with motors connected in place of the leds, first the motors don't run and, even, the code itsef brake !
based on your sketch : this, below, works perfectly with a led... and crashes on the BTS, DUE TO SHORT CIRCUIT BEETWEEN 19 & 21.
At the moment, I have not yet tried to desolder and check the "method 2"... I would like to know your opinion and own experience first.
a big thank you in advance
Philippe

Is a ground connected between the BST and The Controller? According to the spec. sheet, for the BST the lowest working voltage is 3v (logic side). The Esp32 outputs 3.3v. It's possible that 2 BST's maybe dragging the voltage down to much ? If you have Voltmeter, check the Volts between the Pwr & Ground at the BST, when its on and, supposed to be running. The minimum specs on the cheap Chinese boards maybe iffy.

good job

Hello friend.How can I control two 30wtss DC motors by rc?

[@refab2262]

S0rry I can't help I haven't done anything with RC yet. with the microcontroller - yes. w/o it I don't know I will include a link to another U-tuber with the microcontroller. ruclips.net/video/3pYWLF8qw-g/видео.html

Why do you need the potentiometer with the PS3 controller?

[@refab2262]

I use the potentiometer to let the esp32 know the motors position
so, the motor position mirrors the movement of the joystick.

People that can spit out a code like i can spit ou a weld will not give out a code or be helpful from what ive found. As far as hobbies go this community seems to try to not help. They all do the same vids with same nfo. You may be new but more helpful than anyone else. I have a cytron dual driver that requires a microcontroller and havent been successful. Ill try to modify your sketch to work with cytron. If successful ill post a link here.

[@refab2262]

I glad you found my video useful and hope you can get your project going.

[@emilymarin9459]

how did you connect the pins

[@refab2262]

are you referring to the EN-L & EN-R ? I cut the end off 1 of my jumper wires and spliced it into the end of a second jumper wire, thou I could have ran 2 separate jumper wires to the bread board.

Xbox one?

[@refab2262]

Sorry, All I have is PlayStation stuff
