ir reciever TO be Debounced

Other Hardware Sensors
1

i have to make my robot work with remote . When i press 1 on my remote i want to trigger ultrasonic sensors so that it can do obstacle avoidance .

The problem is than the ultrasonic sensor will work only when i keep on pressing the button 1 or when i leave it then the sensor gets off.

So i want to press the button only once and the sensors must work until i press next button.

You will need to provide your code to sort this out.

It is probable that your loop says receive IR, output a sonar pulse and back to start. In that case it will only output with IR pressed.

If IR received and sonarflag false. Detect first IR
Waste time in loop waiting for IR to stop
Set sonarflag

If sonarflag true output sonar. Keep pulsing until next IR

If IR received and sonarflag true. If second IR and sonar pulsing
Waste time waiting for IR to stop
turn off sonarflag
