Objective of group assigenment

• Measure the power consumption of an output device
In this assigenment , we are lerning about output devices that are use in electronics component. we are stearted a group assigenment to study different output devices such as led, oled display, and BO motor. In this activity we tested how these devices work and also checck the power consumption of each component.

1) first we calculated the led voltage and current.
using the on board led. this board we are desgin in last week assigement. we are use simple blink code in arduino ide. this code runing the led turns on and turn off, we are measured the voltage and current to understand how mcch power the led consumes.
Our observation shows that the LED takes 2.824 V and 0.02 mA current.
To calculate power, we use the formula: 𝑃=𝑉×𝐼
V=2.824V, 𝐼=0.02𝑚𝐴=0.00002𝐴,
So, 𝑃=2.824×0.00002
𝑃=0.00005648𝑊
Power consumed by LED = 0.00005648 W

2) Next we calculated the power consumption of BO motor.
we are use simple code to run the BO motor. we ran the code to turn ON the BO motor. The motor is connected to a variable power supply. When the motor is powered ON, the display on the power supply shows the voltage and current consumption of the BO motor. This helps us to measure how much power the motor uses during operation.
Our observation shows that the BO motor takes 12.05 V and 0.125 A current.
To calculate power, we use the formula: 𝑃=𝑉×𝐼
V=12.05V, 𝐼=0.125A,
So, 𝑃=12.05×0.125
P=1.50625W
Power consumed by BO motor = 1.50625 W

3) Finally we calculated the power consumption of OLED display.
we are use simple code to run the OLED display. we ran the code to turn ON the OLED displayshow the name of the display.

the display takes 3.294 V and 0.33 A current.
Using the formula 𝑃=𝑉×𝐼
we calculate the power consumption of the display,
P= 3.294×0.33=1.087 W
Power consumed by display = 1.087 W
