Week 4 - Journal

Operation game

• The player tries to take the toys (components) out from the robot body without touching the edges.

• If the tweezers touch the metal edge, the buzzer sounds and the red led lights up.

• It has a switch to open and close the game.

• Inspired by:

1- Test the circuit components

2- Figure out if the idea is applicable

• Test the conductivity of the aluminum sheet and the tweezers

3- Draw the circuit schematic diagram

• The LED and the buzzer are in parallel connection

• The slide switch used to turn the circuit on and off

• The 220-ohm resistor used to reduce the volt from the 6V power adaptor

Ohm's law

4- Simulate on TinkerCAD (On & Off)

5- Measure LED's current (I2)

6- Measure buzzer's current (I1)

I= I1 + I2

2A= 14.7A+3.38A

A) Circuit wiring

1- Connect the LED with the 6v power supply with 220 ohm resistor using the breadboard

2- Use the aluminum sheet to connect the positive LED and the +ve connected to the sheet

3- Connect the +ve of the buzzer to the sheet and the -ve to the -ve of the LED

4- Add the slide switch to connect the power supply +ve to the resistor

5- Measure LED's current

a- remove the wire that connects the -ve leg of the led to the -ve of the breadboard

b- put the +ve of the multimeter with the -ve leg of the led

c- put the -ve of the multimeter in the -ve of the breadboard

6- Measure Buzzer's current

a- remove the wire that connects the -ve leg of the buzzer to the -ve of the breadboard

b- put the +ve of the multimeter with the -ve leg of the buzzer

c- put the -ve of the multimeter in the -ve of the breadboard

B) Making other parts & Integrating

1- Print the robot body picture

2- Cut the cardboard

3- Cut the aluminum sheet with the same dimenssions

4- Glue

5- Draw holes on the robot body

6- Cut the holes

7- Surround the holes with a small aluminum sheet

8- Glue the aluminum sheet

9- Integrate the body with the circiut
