Computers can transfer data either in parallel or serially. Parallel transmission sends multiple bits simultaneously over multiple lines, and is used for short distances. Serial transmission sends one bit at a time over a single line, allowing data to be transferred over longer distances but more slowly than parallel. The document discusses using serial communication between a microcontroller and LCD, using ULN 2003 to control devices like stepper motors, DC motors, servos, and relays by sending data bit-by-bit over longer distances.
Serial Communication
- 2. Computers transfer data in two ways: Parallel Often 8 or more lines (wire conductors) are used to transfer data to a device that is only a few feet away. Serial To transfer to a device located many meters away, the serial method is used. The data is sent one bit at a time.
- 4. Serial Communication b/w micro controller & LCD.
- 5. Serial Communication is Sending of data from transmitter to receiver bit-by-bit. Transmitter Receiver
- 6. For long distances. Low Cost. The speed of serial Communication is very slow than parallel communication.
- 7. ULN 2003 is used to drive the Actuator. The Actuator used in this project is Stepper Motor. Pin Diagram of ULN 2003
- 9. To control stepper motor , DC motor. Servo motor. To operate Relays.
