Esp32 comunicating data to Arduino uno

Projects General Guidance

Hi, this is my first time writing on this forum, and I don't speak English as my first language, so I'm sorry in advance in case I don't explain myself clearly.

A month ago, I decided to try and make a chair that moves with two hoverboard wheels (brushless DC motors) controlled by a PS4 controller connected to an ESP32.

Now, to control the speed of the motor using these motor controls (https://www.amazon.com/dp/B087M2378D?ref_=cm_sw_r_cp_ud_dp_2XT3VYFE3J4VSA09PP0E), I need to output 0 to 5V. My plan was to communicate the values of the controller to the ESP32 (and I haven't encountered any problems with that) and then from the ESP to Arduino. However, I haven't found any clear way to do it. So, if someone can give me any advice, I am open to all ideas.

Hi @ascari101
welcome to the arduino-forum.

After registering you got presented a link with introductional information that helps you to

You should post your sketches with which you tried to establish communication between ESP32 and Arduino.

creating 0-5V can be done by a transistor, a resistor and a capacitor.
But this seems not to be nescessary
The motordriver has already an PWM-input

This elimiates the need for an arduino completely.

Which could be driven directly from an ESP32 pin

oh ok thank you so much for the reply and the clarification, i thought that the device that sent the PWM had to be at least 5v.
