I have a brushless car ESC with reverse (model HK-30A) that I am using for a non-RC project which runs at one speed from an Arduino microprocessor. The calibration and manual control code is working fine. My goal is to mount the project such that when a standard light switch is thrown and the system powers up, it will drive the motor at the predetermined speed automatically. However, I do not want the self-check sounds from the ESC.
How can I eliminate the sounds the ESC makes on power up? I would like to modify the ESC to eliminate the chimes. Can this be done reversibly? I thought you could provide some guidance before I tear into the unit.
