Presentation Transcript

  1. Robo-week 2013Day-3 • Welcome to everybody. Please take your seat and keep calm.

  2. Todays content • Soldering • Voltage regulator • Sensor basic principle, LDR • Comparator IC Lm324 • Transistor as adriver • Traffic light and line follow circuit

  3. Voltage regulator • Is use for regulated power supply.

  4. Types of rectifier • Full wave rectifier –center tapped & bridge

  5. Light Sensors & source • Light depended resistor • Photodiode • Light emitting diode(led)

  6. Comparator lm324 • Use to compare input voltage with given reference voltage.

  7. Circuit of line follower • Simple transistor as switch

  8. Line following circuit • Simple line follower circuit using LDR & LM324 Without Microcontroller

  9. End of day 3 • Completion of voltage regulator • Completion of traffic light • Familiar with voltage comparator
