Learning Goals
Students learn to connect sensors to the Arduino and breadboard.
Students learn how to program the Arduino to send sensor data serially through the Bluetooth.
General Description
The Arduino Uno, Bluetooth, and breadboard configuration can house a number of sensors. The students will program the Arduino to send sensor information through the Bluetooth as a serial stream of data. In the program, data from different sensors will be separated by the "|" symbol. In the next tutorial a conditional control structure will be used to split the data stream so that the data is appropriately related to each sensor.
Activity 1 (10 minute budget)
Students are provided the instructions on how to connect sensors to the Arduino and breadboard.
1. Teacher hands out the Sensor Descriptions to the students that can be connected to the breadboard that includes the cost of each sensor.
Activity 2 (1 hour budget)
Students learn to program the Arduino to send sensor data serially through the Bluetooth.
1. Teacher shows the Multiple sensors example video (start at 6:18 to 10:48) and models how to program the Arduino and Bluetooth to send data using the photo resistive and microphone sound detection sensors with an emphasis on using the "|" symbol to code the separation of the data of the sensors.
