Look at distance, can use ultrasonic ranging, laser ranging, relevant schematic diagram is very easy to find

look at distance, can use ultrasonic distance measurement, the principle of laser ranging, the relevant figure is easy to find

Good bosses guidance,

CodePudding user response:

Choose close ultrasonic sidelights modules, distance laser ranging module, basic it is through the output of the PWM duty ratios for the distance
