In this chapter, we learned about the different kinds of sensors you can use with the EV3. Common to both editions of the EV3 kit, we looked at the Touch Sensors, the Color Sensor, and Motor Rotation sensors. From the Educational Edition, we examined the Gyro Sensor and the Ultrasonic motion sensor. From the Home Edition, we learned about the Infrared Sensor and Beacon. We briefly looked at how to read sensors both on the computer and on the EV3 brick. We looked at sensors and motor controllers from Dexter Industries, Mindsensors, HiTechnic, MATRIX, and Vernier.

In the next chapter, we will examine how to control the EV3 using the buttons on the robot, and remotely using IR beacon, Wi-Fi, and Bluetooth.
