MY notes: Input, Output setting up Sensors.

Learning about inputs and output devices that can be connected to Arduino.

Explored with various devices such as servo motors, sensors and speakers and then using the appropriate software in Arduino to program them.

There is Digital Input and output, Analogue Input and Output, Serial Output, Simple inputs. Sensors for touch: Force sensitive resisters, is a pad that depending on what pressure is put onto it, it will activate with chosen task, example is a light dimmer.  Stretch sensors are sensors that reaction piezo sensor, flex sensor. A Piezo sensor measures changes in pressure, acceleration, temperature, strain and force.

This animatronic hand is controlled using Force, Bend and stretch Sensors:Robotic hand youtube

Here is a servo motor that moved back and forth at certain speed. The speed could be changed by increasing the value in the arduino code.

In the picture below you will see an Ultra sonic sensor to be used with Arduino or Rasberry Pi. The sonic sensor works on picking up sonar waves so it can track distance. The measurement can be increased or decreased using Arduino code.

They can be purchased for as little as £1.19 from Gearbest

The picture below is a PIR Sensor, they work by sensing motion, they are often referred to as passive infrared, Pyroelectric or IR motion.
