In Chapter 2, Weather Station (IoT), we had a brief discussion about sensors. Here we are more focused on sensors that will help the robot find where exactly it is in an environment. We are going to deal with two sensors and how you can calibrate them:
- Ultrasonic sensors (HCSR04)
- Infrared sensors for detection of lines
The reason behind the use of the preceding sensors is that we use these sensors in robotics. However, others are also used, but these are the most commonly used. Now the next question that arises is "how do they operate and how do we hook up with the Intel Edison?"
Let's have a look at each of them.
