How to control ESC from Arduino?

There are quite a few issues I see with your setup. You are setting up the ESC in your code to use pin 9, but your diagram shows that you've connected to pin 8. Pin 8 won't do anything because the ...

Electronic Speed Controller

It depends on the voltage. Say you are running 12V: 1820W / 12V = 151A With a 24V system: 1820W / 24 = 75A

Bldc motors erratic behavior with Arduino program

Can you make a written description (comments, text, or block diagram) of what you think the code is supposed to be doing? I can't figure out what your whole timer scheme is supposed to do. Here's ...

wheeled vehicle forward velocity from RPM brushless data

This project does exactly that on an RC car. The author is a top competitor in the DIYRobocars community; it's the blue car in this video. He uses tachometry from the brushless motor, an IMU and ...

Automatic forward and reverse Brushless Motor

This is a simple problem which can be solved with an Arduino, Brushless ESC with forward and backward capabilities, thats all. You need to program the Arduino to provide a PWM signal to the ESC, it'...

Automatic forward and reverse Brushless Motor

The motor in your list is sensorless meaning that there is no provision internally for commutation feedback. Such a motor cannot be operated reliably below 10-20% of it's maximum speed and it ...

Automatic forward and reverse Brushless Motor

The DC motor you have is a brushless type typically used to turn a propeller on a drone. It can go in 'reverse' using an brushless ESC that supports reverse. I would not think most ESCs used for ...

Automatic forward and reverse Brushless Motor

This motor in video is stepper motor. If you want to move brushless motor that you have, you have to buy ESC that can support 2-way rotation. You can also add a relay that switches 2 phases from ESC, ...

What control circuit element will control an ESC while doing bench testing?

To Control an ESC, or rather, give a control signal, one generally uses some kind of micro controller (arduino, esp32, Ti c2000, STM, countless others) with a ESC dependent control signal. The mcus ...

Esc calibration

Missing a few information, so I will assume the following: - Using the instruction analogWrite() to send pulses to the ESC. - Not using the Mega pin 4 or 13. - your map() instruction is converting ...

Quadcopter ESC failure on first test flight

On the bench without propeller your motor as virtually no load, hence the current drained from the ESCs is rather low. Then seeing the average price of your ESCs on the internet I would not be ...

What happens when I connected my unpowered servo connector power wire to the powered arduino 5V pin?

Should be fine. If I remember correctly, the inputs to the ESC (more or less) control power mosfets. Putting input to a mosfet without power does not hurt it.

Brushless motor from RC car won't spin with even small resistance
