Week #7 - Journal

Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you? (Please include images or links to sources of inspiration)

Barrier Gate

I was inspired by the barrier gate.

It is easy to replicate it using a servo motor and ultrasonic sensor.

Tool Chain

Which software/machines/materials did you use in the assignment? Why?

Software

I used Tinker CAD to design the circuit and to simulate the text code.

I used Arduino IDE to upload the text code on the Arduino UNO board.

Electronic components

3- 220-ohm Resistor / RGB LED

Adjusts the current passing through the RGB LED, which is going to indicate the gate open/closed

Jumper wires

Connecting the components.

Breadboard

To fix the components in and connects them together.

Arduino UNO board

will be connected to the inputs and the outputs and power them. It is also going to run the code on the components.

Ultrasonic sensor

Is going to be our input, when it senses a person or an object, the output component is going to work

Servo Motor

will resemble the gate door responding to the ultrasonic sensor

Push Button

to open the gate with the manual mode

Slider Switch

to switch between manual and automatic mode.

Design/Preparation Process

Explain the design and/or preparation process of your assignment. How did you use the tool or software to design and/or prepare your assignment before fabrication/implementation?

The circuit on TinkerCad

RGB LED connected to pin 4, pin 3, and pin 5
Ultrasonic sensor trig connected to pin 6

echo connected to pin 7

Servo Motor connected to pin 9
Slider switch connected to pin12
Push Button connected to pin 11

In this simulation

Ultrasonic sensor is an Input.
Slider switch is an Input.
Switch button is an Input.
RGB LED is an Output.
Servo motor is an Output.

Automatic Mode:

When an object is 50 cm far or less from the Ultrasonic sensor, the servo motor opens to 90 degrees, and the light turns green, if not the servo stays 0 degrees and the light is red.

Manual Mode:

When you push the button, the servo motor opens to 90 degrees and the light turns green, when the button is released the servo stays 0 degrees and the light is red.

You can switch between the two Modes through the slider switch.

Development/Implementation Process

Explain the development/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?

I started coding on Arduino IDE with the Arduino-Ultrasonic Sensor-Servo Motor project code. This project already had the Ultrasonic Sensor controlling the servo motor. I had to add the RGB LED output then the slider switch and the push button to have an automatic and a manual mode

Code *.ino

I tested the final code on TinkerCad and it worked with both the manual and the automatic mode.

Timeline 1.mov

I wired everything with the actual components, uploaded the code and it worked.

Timeline 1.mp4

Timeline 1 (1).mp4

Overcoming Challenges

What kinds of challenges or problems did you face while doing the assignment, tutorials, or exercises? How did you solve them? Did you ask for help from an instructor or peer? Please provide a link to the tutorial or article that you used to solve your problem (if any)

Throughout this week I struggled with coding and thought I could never do it.

I took a break from the assignment and after a second look, I realized the problem was wrong wiring with the slider switch.

Re-checking the end-of-week session activity, I followed the steps of switching between manual and automatic modes, after correcting the wiring of course, and it went well.

Wrong wiring of slider switch

After the code was done, I found the servo motor making a noise but not moving, I thought it was broken. I asked my instructor and he suggested powering the servo motor with a 5V adapter and connecting the ground of the adapter and the Arduino and it worked perfectly.

Final Project

How can you use the skills and knowledge that you've acquired this week in your final project?

This week made me more comfortable with coding and thinking of the steps in simpler ways to make the project happen. This will definitely help with making the final project exceptional.

WOW!

What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

{

Learning how to use this program is exaptational. I never thought I could be able to write code and it never crossed my mind that if I tried I would succeed;

Learning about the open-source community and how easy it would be to find similar codes for your project and build on it to get the desired outcome;

Arduino IDE

Weekly Digest [OPTIONAL]

Tell us about any other cool things that you've made this week: in the Hands-on activity, tutorial examples, exercises, or any other cool mini-project that you tried out aside from the assignment.
