Speed Control with IR Remote

This C++ code implements a speed control system using an IR remote with an Arduino board and a liquid crystal display (LCD). The system allows users to adjust the speed of DC motor connected to the Arduino's PWM pin based on the received IR remote signals.

Components Used

  • Arduino board
  • IR receiver module
  • IR remote
  • Liquid crystal display (LCD)
  • Bulb connected to PWM pin

Libraries Required

  • LiquidCrystal.h: A library for controlling LCDs.
  • IRremote.h: A library for receiving and decoding IR signals.

Pin Configuration

  • receiver: Pin 10 (connected to IR receiver module)
  • buld: Pin 9 (connected to the bulb)
  • LCD Pins: (12, 11, 5, 4, 3, 2)

Functionality

  1. The system initializes the LCD, sets up IR remote reception, and displays a startup message.
  2. The loop continuously checks for IR signals. Upon receiving signals:
    • If the received signal corresponds to code1, the counter increments, adjusting the brightness level up.
    • If the received signal corresponds to code2, the counter decrements, adjusting the brightness level down.
  3. The counter value is bounded within the range [1, 5].
  4. Based on the counter value, the PWM value for the bulb is adjusted accordingly, and the corresponding status message is displayed on the LCD.

Counter States

  • 1: Dimmer Off
  • 2: Dimmer On, Speed 1
  • 3: Dimmer On, Speed 2
  • 4: Dimmer On, Speed 3
  • 5: Dimmer Max

Notes

  • The PWM value is adjusted to control the brightness level of the bulb.
  • IR remote signals code1 and code2 are used for increasing and decreasing the brightness levels, respectively.
