Week 4 - Journal

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What were you inspired by?

I inspired by the Sunrise alarm so I design a small circuit with LDR to sense the light of the sun and reduce the resistance then allow the current to arrive at the buzzer and make sound and to the 7 segments

Which software/machines/materials did you use this week? Why?

VID_20210130_205506.mp4

use tinkercad program to simulation the electronics circuit. We work on the multimeter and different electronics components like photoresistor, thermostat, potentiometer, 7 segments, and extra.

Explain the design process of your assignment. How did you use the tool/software to design and/or simulate your assignment?

First, I design a schematic circuit and calculate the volt, current, and resistance.

Second, I draw my circuit on tinkercad to stimulate it and make sure it will work well.

Third, I use the breadboard and the components to make the circuit.

Finally, I test the circuit and measure the voltage and current using a multimeter.

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

I use a breadboard and these components to complete the project

Componentes

2 7-segments

1 LDR

1 buzzer

1 resistance 10 kohm

2 resistance 1 kohm

1 on\off Switch

1 LED

Wires

calculate the current and volt : V= I R

LED I = 6V \ 10 000 = 0.6 mA

V=4.66 I = 0.6 mA

LDR resistance = 4.66\0.0006=7.766 Kohm

Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

Some of my peers ask for a tutorial to use the multimeter, so I sent some YouTube videos to help him

When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this project?

I faced a problem on tinkercad with 7 segments so I watched different videos even I reach the solution.

The solution is the 7 segments in the tinkercad is a cathode common not an anode common.

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

When I think about the circuit design I should be careful to the current and voltage measurement.

I will use the tinkercad and others tool to stimulation the circuit before making it in the real, to try it and make sure everything is Wright

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

Knowing how tools are made, what is inside them, and how they do them action

Tell us about any other cool things that you've made this week: Pre-activity, examples, exercises, or any mini-projects.

Yes, I made a thermostat circuit, LDR circuit, and use a buzzer and potentiometer.
