Setting up the Circuit and Outputting Values — Lucky Larry. First things first, we need to build our circuit. We’ll be using the Arduino to control a servo that will rotate our sensor around 1. The Arduino will then send the value from the distance sensor along with the current angle of the servo to the serial port. Before proceeding please take a moment to check out some of my other work with the SRF- 0. Arduino SRF- 0. 5 Tutorials. Arduino Servo Tutorials. I’m building this with the SRF- 0. I think I’ll end up trying a different range finder maybe an IR one as the SRF- 0. Then we have the servo output pin going to Arduino digital pin 9 and the SRF- 0. You’ll notice that in my pictures I have 2 servos – I’m just using the bottom one of the pair to rotate the sensor round. On your servo you’ll need to figure out a way to mount the sensor on to the servo wheel – I used a lot of blu- tac! You’ll also see I’ve mounted my sensor vertically so that the when the servo moves there’ll be less interference with recieving values – placing the sensor horisontally seemed to give differences of up to and sometimes over 5cm between the first and second readings. My servos do tend to move a bit so I’ve used more blu- tak/ modelling clay to hold them down and in place – if the servos move other than the way they’re meant to then it means dodgy readings. Arduino SRF0. 5 Radar Sketch. The hardest bit – rotate the servo from left to right, then right to left and for every degree of movement take a series of readings and send them to the serial port. We’ll want to produce an average reading value for consistancy. Unfortunately with this ultrasound sensor we have to be quite slow to make sure we’re getting accurate values and we have to allow time for the signal to come back each time and register in order to produce the average value. We do the rotation using a for loop to count to 1. During this loop we do another FOR loop to count to 1. Readings and for each iteration we add the distance measured to the total and after 1. Then reset the total and the counter to start again for the next servo position. Play Lucky Larry's Lobstermania 2 slots today! Join Pocket Fruity for the best mobile slot games experience!

The last line is using println which will start a new line for the next set of values – each reading has its own line in the serial buffer makign it much easier to get our values back out./*.
