Sensors and Actuators Assignment

1. Introduction
The homework given was to introduce sensors and actuators using Arduino.

2. Results

1. Explain why the full bridge is the most sensitive to one resistance variation using calculations. The quarter bridge is 1/4 of the sensitivity of the full bridge and the half bridge is half the sensitivity of the full bridge.


2.  Use an ultrasonic module to measure the distance using the HC-SR04 without using SR04.h library.

 

3. A function generator was used to create a 5V pulse. The Arduino sensed the pulse and delivered a 400 µs pule 800 µs later on an oscilloscope.

4. A MPU6050 and buzzer were used to create a vibration detector.


5. A joystick was used to control the speed and direction of a NEMA stepper motor.


6. A rotary encoder was in this problem. When the rotary encoder was turned counterclockwise and A changed from LOW to HIGH state, B was HIGH. When turned clockwise and A changed from LOW to HIGH, B was low.





3. Discussion

This homework allowed me to gain experience with different sensors and actuators. Implementing them on Arduino allows me to see the functionality of the sensors.
