Circuit Design for Automatic Dustbin Lid Opening | Science Project

In summary, the conversation discusses creating a circuit for a science project that automatically opens a dustbin lid when a person passes by. Possible components include a proximity sensor, microcontroller, servo motor driver, and servo motors. Fresnel lenses and infrared sensors are recommended for people sensing. It is also suggested to use a solenoid or passive infrared sensors for a simpler approach. Sparkfun.com is suggested as a resource for further information.

hi everyone! for my science project, i want to create a circuit which automatically opens the lid of a dustbin when a person passes by the dustbin. Is there a particular type of circuit that i can use to accomplish this?

What do you mean by particular type of circuit?
The general idea would be something like -

proximity sensor --->Microcontroller--->servo motor driver-->servo motors.

Proximity sensor, like an ultrasonic sensor or infrared sensor etc would sense the person and send a signal to a Micro.
Micro would then drive a servo motor thru a servo drive circuit. The servo motor would open the lid.
You could eliminate the Microcontroller and wire the sensor directly to the servo drive circuit.

haven't worked with servo motors yet. Could you give me the name of sites that would be a good place to start off one's experience with servo motors?

Even simpler than a motor, use a solenoid from your old washing-machine to open the lid.

Also look for Passive InfraRed (PIR), like your porch light thing-a-ma-bob, and close range IR sensors to trigger the thing. Once again I recommend sparkfun.com ...

What is circuit design?

Circuit design is the process of creating a circuit, which is a complete and closed path for an electric current to flow. It involves designing and arranging electronic components such as resistors, capacitors, and transistors to achieve a desired function or behavior.

Why is circuit design important?

Circuit design is important because it allows us to create electronic devices that perform specific functions. It also ensures that the device operates safely and efficiently by controlling the flow of electricity. Without proper circuit design, electronic devices would not work as intended or could potentially be dangerous.

What skills are required for circuit design?

Circuit design requires a combination of theoretical knowledge and practical skills. This includes a strong understanding of electrical principles, knowledge of electronic components and their behaviors, and proficiency in using design software and tools. Attention to detail, problem-solving abilities, and creativity are also important skills for circuit design.

What are the steps involved in circuit design?

The steps involved in circuit design may vary depending on the complexity of the circuit, but generally include the following:

  1. Defining the purpose and specifications of the circuit
  2. Researching and selecting appropriate components
  3. Creating a schematic diagram
  4. Designing the layout of the circuit board
  5. Simulating and testing the circuit
  6. Prototyping and making necessary adjustments
  7. Finalizing the design for production

What are common challenges in circuit design?

Some common challenges in circuit design include managing power consumption, minimizing noise and interference, ensuring compatibility between components, and dealing with limited space on the circuit board. Troubleshooting and debugging can also be challenging when unexpected issues arise. It is important to have a thorough understanding of circuit design principles and to test and iterate the design as needed to overcome these challenges.
