Determine the Liquid Crystal Display(LCD) (Week 6)

• the objective of the LCD is to show the degree of change in direction of the headlight

     A liquid crystal display (LCD) is a flat panel display, electronic visual display that uses the light modulating properties of liquid crystals.

     It is an electronically modulated optical device made up of any number of segments filled with liquid crystals and arrayed in front of a light source (backlight) or reflector to produce images in color or monochrome

Example of 2x20 LCD

Identify the Type of Motor (Week 5)

• to identify electrical motor to move the direction of headlight

For this project I choose Servo motor to move the headlight. The advantages of the servo motor are 

1.  High output power relative to motor size and weight
2. Encoder determines accuracy and resolution
3. High efficiency. It can approach 90% at light loads.
4. High torque to inertia ratio. It can rapidly accelerate loads.
5. Has "reserve" power. 2-3 times continuous power for short periods.
6. Has "reserve" torque. 5-10 times rated torque for short periods.
7. Motor stays cool. Current draw proportional to load.
8. Usable high speed and torque. Maintains rated torque to 90% of NL RPM.
9. Audibly quiet at high speeds.
10. Resonance and vibration free operation.

Determine the type of light sensor (Week 4)

• to determine the sensitivity of light sensor to the ambient of light
• to determine the input voltage of the sensor

The ambient light sensors that I have researched were TEPT 5600 and TEMT 600X01

Preparing Project Proposal (Week 3)

• to determine the objective of the project, budget and the list of component.
