Week 9: Output Devices

Output Devices

Assignment activities:

I.Individual assignment:

Add an output device to a microcontroller board you've designed, and program it to do something

II.Group Assignment:

Measure the power consumption of an output device

If you want to explore the group Assignment Click Here

In Group we Mesure voltage, Current and calculate the power of our board

Here we are mesuring a voltage of board

Here we are mesuring a Current of board

Here we are calculate the output Power

Individual Assignment

In this Assignment I designed a board which will have output as LCD (Display) as an output device, which will desplay some message we put in our system and we use also ESP23 Microcontroller, ESP23 Datasheet this board I will also use it in my final project.

Here is Schematic Design

Here are a list of components I will use

Here is The Board

Here is The Board after milling

The following Image shows when I started soldering my Board

The following code are used to generate an image robot

By using a Programmer I made in the week of Electronics Production Here is a picture of my output which display an image in OLED Screen

The following Video shows how I displayed my output
