A very thorough and comprehensive tutorial of Sharp detectors controlled with Arduino. Excellent job. Thank you.

Awesome ! I had Some troubles with 2 tfmini and UNO programming and as soon as i saw this tutorial i changed my aproach and it went nicely. Thank you so much!

It's a great presentation; many thanks to you. I tried this example with two IR-sharp 10 to 80 cm sensors, but I'm getting the same distance with the two sensors even if I focused each one at a different distance. I need someone to help me out.

Writing to see if anyone has performed any tests with reflective
adhesive tape for objects that are particularly troublesome for the
Sharp IR Distance sensor. Thank You!

Thanks for the video! I am working on a project using 42 of these sensors at the same time, just using one arduino. I am using 3 multiplexers, so I need only 3 analog pins on the arduino. Now it seems that the power supply of the arduino is not capable to deliver enough energy for all the sensors and connecting them to a external power supply does not seem to work as they need to share at least the ground with the arduino I guess. Do you have any raccomandations how it could be possible to drive a very large amount of these sensors with just one arduino?

Hie, thank you for the video. Am learning as a beginner and would like to add an LED to light up if motion is detected within a given distance, say 40 cm from either side of the two sensors.

'class SharpIR' has no member named 'distance' how can i solve it ?

[mohanedalthagafi]

Can you store the data onto a USB and have the Arduino portable

Öncelikle kolay gelsin.Servo motorla kullanışını da anlatırsanız seviniriz

I have pololu sumo(zumo) robot and i want to use it on my sumo robot. It is very important for me. Could you please help me with code part?

[purplefurture]

hello, 50 is what ? cm or mili ?
i spend 6 hours cant fix it
int dis1;

void down1(){

while(dis1<50){
dis1=SharpIR1.distance();
delay(500);
}

}
