\n-your own cardboard mount to attach the ultrasonic sensor
\n-use a small breadboard to mount the sensor – please glue this down – DO NOT PEEL the adhesive off.<\/strong><\/span>\u00a0 Pay close attention to HOW the sensor is attached to the breadboard.

\n-4 wires for the sensor<\/p>\n
\n1. your robot should turn when it encounters an obstacle.
\n2. after the turn is completed your robot should drive straight until it detects another obstacle.\u00a0 Then it will repeat step 1.<\/p>\n
\n1. you need to wire the ultrasonic sensor \u00a0following the diagram in Ultrasonic Sensor Part 2<\/a>.|
\n2. you need to remove the button and replace it with a wire.\u00a0 Click here to see what this looks like.\u00a0<\/a><\/p>\n
\nYour program should include a function that tells the robot what to do while it is searching for an obstacle. If you need a refresher on Arduino Functions follow this link.<\/p>\n
\n<\/strong>1. make a copy of your code from the first version of this robot.
\n2. click here for starter code.\u00a0<\/a> \u00a0You will need to add your OWN code for making the robot drive straight, stop and turn.
\n3. you only need ONE loop function (named void loop() ).\u00a0 Don’t add a second loop function.\u00a0 Instead, modify the one that you already have.<\/p>\n
\n1. setup some boxes as obstacles.
\n2. let the robot drive towards the obstacles.
\n3. questions…
\n>does it stop?
\n>does it turn?
\n>does it have enough room to turn?<\/p>\n
