Raspberry Pi 4B Servo Motor Controller PWM Kit, 2-DOF Pan-Tilt HAT for RPi Light Intensity Sensing Control Camera Movement I2C

Description

The Raspberry Pi 4B Servo Motor Controller PWM Kit is a device that allows you to control up to two servomotors from a Raspberry Pi 4B. The kit includes a light intensity sensor which can be used to adjust the position of the camera based on ambient lighting conditions.

Features:
– Compatible with Raspberry Pi 4B
– PWM control for servomotors
– Integrated light intensity sensor
– Control two servomotors
– I2C communication

Use: Ideal for projects requiring panning and tilting a camera, such as security or environmental monitoring systems. Use it to create a pan-and-tilt system for a camera using two servomotors. The light intensity sensor can be used to orient the camera towards the light.

Tutorial: How to use the Raspberry Pi 4B Servo Motor Controller PWM Kit
This PWM control kit allows you to control up to two servomotors from a Raspberry Pi 4B. It is ideal for projects such as panning and tilting a camera or any other angle control system.
What’s needed:
– Raspberry Pi 4B
– Servomotors
– USB cable for power supply
– HDMI cable
– Monitor or TV with HDMI input
– Wi-Fi or Ethernet network
Steps:
1. Connect the PWM kit to the Raspberry Pi 4B using GPIO connectors.
2. Configure the Raspberry Pi with Raspbian or another Linux distribution.
3. Install necessary PWM control libraries.
4. Verify I2C connectivity between the PWM kit and the Raspberry Pi.
5. Connect servomotors to the PWM kit.
6. Write a Python script to control the servomotors.
7. Test servomotor movement.
8. Add the light intensity sensor for automatic control.
Example code:
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.OUT)
pwm = GPIO.PWM(18, 50)
pwm.start(0)
try:
while True:
for dc in range(0, 101, 5):
pwm.ChangeDutyCycle(dc)
time.sleep(0.1)
for dc in range(100, -1, -5):
pwm.ChangeDutyCycle(dc)
time.sleep(0.1)
finally:
pwm.stop()
GPIO.cleanup()
Mini-project: Create a pan-and-tilt system for a camera with two servomotors. Use the light intensity sensor to orient the camera towards the light.
Common issues:
– The PWM kit is not recognized by the Raspberry Pi.
– Servomotors do not move correctly.
– Light intensity sensor does not work properly.
– Power supply issues for servomotors.
