Transcript of "Hardware Wrkshp C [Compatibility Mode]"

  1. 1. ABOUT HARDWARE FROM:JJ/2009/PART2
  2. 2.  Working IR Tx and Rx Module Working Motor driver module Power supply for Microcontroller Oscillator for Microcontroller Reset circuitry for Microcontroller Matrix Key Board 4x4 LCD in 4 Bit mode FROM:JJ/2009/PART2
  3. 3. FROM:JJ/2009/PART2
  4. 4. Application of IR Tx and Rx Module•obstacle sensing,•color detection,•fire detection,•line sensing, FROM:JJ/2009/PART2
  5. 5. FROM:JJ/2009/PART2
  6. 6. Motor driver is basically a current amplifier which takes a low-currentsignal from the microcontroller and gives out a proportionally highercurrent signal which can control and drive a motor.>Output current up to 1.2A>Supply voltage can be as large as 36 Volts>over temperature protection" built into the IC.>This flyback diode helps protect the driver IC from voltage spikes thatoccur when the motor coil is turned on and off>The logical low in the IC is set to 1.5V.> high frequency applications upto 5KHz How does DC Motor work ??? FROM:JJ/2009/PART2
  7. 7. Require more current then the microcontroller pin cantypically generate Transistor as a current amplifier to provide required current to drive the motor FROM:JJ/2009/PART2
  8. 8. •Turning on Switches A and D makes the motor rotate clockwise•Turning on Switches B and C makes the motor rotate anti-clockwise•Turning on Switches A and B will stop the motor (Brakes)•Turning off all the switches gives the motor a free wheel drive•Lastly turning on A & C at the same time or B & D at the same timeshorts your entire circuit. So, do not attempt this. FROM:JJ/2009/PART2
  9. 9. >Pin2, Pin7, Pin10 and Pin15are logic input pins. These arecontrol pins which should beconnected to microcontrollerpins.>Pin2 and Pin7 control thefirst motor (left); Pin10 andPin15 control the secondmotor(right). High ~+5V, Low ~0V, FROM:JJ/2009/PART2
