Remote Learner

Abstract

The objective of this project was to create a remote learner using the SJOne board. The Remote Learner would have the ability to be controlled by an Android application using Bluetooth. The application would tell the SJOne board to learn a remote control using the IR sensor or transmit the remote command via IR LED..

Objectives & Introduction

Show list of your objectives. This section includes the high level details of your project. You can write about the various sensors or peripherals you used to get your project completed.

Parts List & Cost

Give a simple list of the cost of your project broken down by components. Do not write long stories here.

Line Item# Part Desciption Vendor Part Number Qty Cost ($)
1 120 Resistor Anchor Electronic N/A 10 1.00
2 IR LED 1.5 V 40mA Anchor Electronic N/A 4 1.00

Design & Implementation

The design section can go over your hardware and software design. Organize this section using sub-sections that go over your design and implementation.

Hardware Design

Discuss your hardware design here. Show detailed schematics, and the interface here.

Transmit IR LED:
The IR LED transmitter is a simple circuit that connects to a PWM pin that is set to toggle at 38 Khz. The circuit needs a resister to create the voltage drop for the IR LED.

Hardware Interface

In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.


PWM to IR LED:
The PWM was used to generate the 38 Khz by creating an instance of PWM class. Then using the predefined function of "pwm.set" to toggle the pin at a duty cycle of about 25% and after certain amount of time we set the duty cycle to 0.

Software Design

Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.

Implementation

This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.

Testing & Technical Challenges

Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.

Include sub-sections that list out a problem and solution, such as:

My Issue #1

Discuss the issue and resolution.

Conclusion

Conclude your project here. You can recap your testing and problems. You should address the "so what" part here to indicate what you ultimately learnt from this project. How has this project increased your knowledge?
