	Arduino Uno Single Board Microcontroller A computer on a board with everything you need to start running programs and interfacing with the real world. Includes CPU, flash, EEPROM and static RAM memory,digital and analog I/O, timers and more.
	Ultrasonic Module HC-SR04 Distance Sensor For Arduino Ultrasonic transmitter and receiver. Operates by sending out ultrasonic pulses of sound and measuring the time it takes to receive an echo.
	1602 Keypad LCD module Plug in LCD and Keypad shield for the Arduino Uno. Provides 2 lines of 16 characters on a backlit LCD display plus 6 small key switches that are easily accessible from software.
	Mini Solderless BreadBoard A 170 point mini breadboard is perfect for this project
	Hook-Up Jumber Cable Wires You can make these yourself with some flexible wire, solid copper wire and heat shrink sleeving if you can be bothered to spend the time soldering them all up. Why not make your life easier and buy a fistfull instead. They are not expensive.

One quick question. How does the LCD know what to do? How do you make that connection from the Arduino to the LCD? That's the part I'm having trouble with, I can't figure out what pins from the Arduino that I need to connect to the LCD then the LCD to the Ultrasonic sensor

HI,
I was wondering if the same code can be used with a normal 16X2 lcd which comes without the keypad shield. What are the changes I need to do in order to make the same project run on a normal 16X2 display?
Thanks

Very nice presentation. I think there are a couple of areas where you could simplify your code without changing it's function. Your 50us pulse is going to be high then low, then high, then low every 50us. Your call to your routine is nice, but the routine could be simplified... void trigger_pulse() { static volatile bool state=0; state=1-state;digitalWrite(trigPin,state); } And your routine for weighting the hits... for(i=0,i<RANGES,i++) { if(i!=found_hit) { ...

This code was just what I was looking for and then some. I am building some robot classes and needed logic like this to handle my obstacle sensor.

The inclusion of the LCD code got me over another hump as well.

I will be "cleaning up" this example to encapsulate its functionality a bit better and then incorporating it into my robot code. I will post what I have once it's working.

Hi Bob,

I'm pleased the article has helped. I would be very interested to see how your project turns out.
