However, this value may change slightly depending on the characteristics of the ultrasonic transmitter and receiver, including interference due to wave reflection from the environment if the tested area is not an open area.
  • Page 35 Start the operation by waiting for the S1 button on the KidBright32iA board of the KidBright32iA JR-BOT robot to be pressed. When the S1 button is pressed, the KidBright32iA JR-BOT moves forward and checks if the reading value of the I2 input is less than 500. This value is approximately 15 centimeters.
