- This system is about programming a 8052 microcontroller for Obstacle Avoidance System using Keil Software.
Components
- 8052 MC.
- Infrared transmitter and receiver.
- Crystals
- CH340 USB to Serial chip.
How it works
- By using timers and interrupts.
- A modulated signal of 38Khz is generated and is transmitted by the infrared transmitter when the button is pressed.
- If there is an obstacle, the light wave is reflected and is captured by the infrared receiver which LED lights up.
