Blinking a Led:  This led can be turned on or off and it can repeat this forever and it will do this very fast depending on your manipulation.

• Code , picture and video without manipulate .

Manipulated code : We had to manipulate the code that helps with the movement, the intensity of the LED light. The code that helps with the fastest LED is .

RGB LED :  It has 3 different colors which helps to change any other color (create color scheme) and the colors are blue, red and green.

Push Bottoms : When you press the bottom, the LED will light up.

Photo Resistor : It is a light sensor and the light increases depends on how much sensor it receive

Temperature sensor: It is a sensor  that we can use for  measure ambient temperature .This sensor is composed for three pins; a positive ;a ground and  a signal.

A single Servo:  This system made a move to 0 to  180degrees, so with this we learned to use a PWM( pulse diameter modulation) that gonna help to control and the rotation of a servo 

Original code and video : With this we can see that how did the move of 0 to 180 degrees.

Manipulate code and the video : Here we can see how we can not put in 360 degrees and how reacted because the max degrees is 180 I mean the half of a circle.

• Here we can see how the spinning of the motor change when we change the speed  0 -255.

Relays: It is  a electrically-controlled mechanical switch, This circuit is using for many things including cars.

• Code and the video : Here we can see how the led changes as we listen to the sound when we press delay. 

Shift Register: Now we learned how we can use eight led at the same time and we can appreciate how the led on and off like a wave.
