3. Test Robot Sensors (Inputs)
We need to test the Robot's sensors (outputs). To do this we need to upload a program that will display the IR line sensor and ultrasonic sensor values to the Arduino Serial Monitor and the LCD screen if you have that plugged into the robot.
You can open Little_Bot_Read_Sensors in Arduino IDE or open the code at Create.Arduino.cc then you can upload to your Little Bot. Please note typical sensor values over different surfaces and distances.
