BLDC with Hall PID Test 02/08/22

So, this one is working. I had a problem with one of the other motors with the signal output/input. I swapped the motor out with a 12000RPM and set it to approximately 6250 and applied pressure with my finger to slow it down. Looks like it is keeping a fairly constant speed according to the Hall output into the tachometer. I have a feeling that the tachometer isn't super accurate but we're heading in the right direction.

Hello sir, can you please share the code you used in this ? I'm using similar motor driver, JYQD-V7.3E2

Please explain?

PID controlled by Arduino in closed loop. BLDC hall output is aggregated through the driver board and sent out as a 12 Pulse per revolution signal square wave. The Arduino reads the square wave and adjusts the speed of the motor using a PWM signal back into the driver board.
