Hello there,
I have a parking sensor that I am modifying to be a proximity sensor on a power wheelchair. Currently the sensor is attached to a light system with a speaker. This portion has the circuit board in it. The when the sensor detects objects at certain distances it will light up (green, yellow, red) and sound an alarm (varies by frequency depending on the distance- correlates with the green, yellow, red light). The problem is that this system works perfectly for signaling when the wheelchair is backing up and is too close to something (red) but when at a safe distance (off or green) it also beeps. I am wanting to know if the circuit board can be modified to not include the sounds for green (possibly yellow) distances. I am attaching photos of the system and circuit board
