In this Intermediate Arduino lesson students will get hands-on experience learning how to use the Ultrasonic HC-SR04 Distance module and Serial Monitor to measure distances between 30 and 300 cm using ultrasonic display analog readings.
Students will use data from the analog sensors and 3 LEDs to create their own portable temperature and light meter.
Prerequisite: 3R's Robotics Basic, Adult, Jr. Arduino class or the ability to configure and load basic programs on an Arduino.
Students should bring a laptop (PC or Mac), otherwise MakerPlace can provide laptops for those who do not bring their own, as well as their Arduino Uno Rev 3 and Breadboard. If a student does not have their own Arduino and Breadboard one can be provided for them (please see the materials fees below).
There are two options for material costs for this class:
Option 1 - $15.00 - includes Ultrasonic HC-SR04 Distance Module, LED's, jumper wires and resistors. Students provide their own Arduino and Breadboard.
Option 2 - $45.00 - includes Ultrasonic HC-SR04 Distance Module, LED's, jumper wires and resistors. The instructor will provide an Arduino Uno Rev 3 and Breadboard for student.
