Project Examples
This section presents two distinct projects, one showcasing electrical/electronics engineering and the other mechanical engineering, to illustrate the differing principles and design approaches employed in each discipline. The projects are simplified for clarity but represent typical applications of each field.
Simple Automated Lighting System (Electrical/Electronics Engineering)
This project details the design of a simple automated lighting system triggered by an ambient light sensor. The system will turn on a light when the ambient light level falls below a certain threshold and turn it off when the light level rises above that threshold.The system comprises an ambient light sensor (photoresistor), a comparator circuit, a transistor acting as a switch, and a light bulb.
The photoresistor’s resistance changes with ambient light levels. The comparator circuit compares the photoresistor’s resistance to a reference voltage. If the resistance is high (low light), the comparator output will be high, turning on the transistor and illuminating the light bulb. Conversely, low resistance (high light) results in a low comparator output, turning off the transistor and the light.
Schematic Diagram: Imagine a simple circuit diagram. On the left, an ambient light sensor (photoresistor) is connected to one leg of a voltage divider. The other leg is connected to a stable voltage source (e.g., 5V). The output of the voltage divider is connected to the inverting input of an operational amplifier (op-amp) configured as a comparator. The non-inverting input of the op-amp is connected to a potentiometer, allowing adjustment of the reference voltage.
The output of the op-amp is connected to the base of an NPN bipolar junction transistor (BJT). The collector of the BJT is connected to the positive terminal of the light bulb, and the emitter is connected to ground. The light bulb’s other terminal is connected to the positive terminal of the voltage source.
Parts List:
- Ambient Light Sensor (Photoresistor)
- Operational Amplifier (Op-amp)
-e.g., LM741 - NPN Bipolar Junction Transistor (BJT)
-e.g., 2N2222 - Light Bulb (Low Voltage LED or small incandescent bulb)
- Potentiometer (for adjusting the light threshold)
- Resistors (various values for voltage divider and current limiting)
- Power Supply (5V DC)
- Breadboard and connecting wires
Design of a Simple Lever-Operated Mechanical Claw (Mechanical Engineering)
This project Artikels the design of a simple mechanical claw operated by a lever. The claw is intended for picking up small objects. The design prioritizes simplicity and functionality, focusing on basic mechanical principles like levers, linkages, and gripping mechanisms.The claw consists of a lever arm pivoted at one end. The other end of the lever is connected to a linkage system that opens and closes the claw.
The claw itself is composed of two jaws that can be moved relative to each other by the linkage. The lever’s movement provides the force to open and close the jaws. The entire mechanism can be built using readily available materials like wood, metal, or 3D-printed plastic.
Conceptual Drawings: Imagine a simple sketch. A lever arm is shown pivoting on a fixed point (e.g., a screw).
The far end of the lever connects to a simple linkage mechanism, possibly using a series of rods and joints. This linkage is connected to two jaws that form the claw. When the lever is moved downwards, the linkage moves the jaws together, closing the claw. When the lever is raised, the jaws open.
Mechanical Components:
- Lever Arm (material: wood, metal, or 3D-printed plastic)
- Pivot Point (screw or bearing)
- Linkage System (rods, joints, possibly springs for return mechanism)
- Claw Jaws (material: wood, metal, or 3D-printed plastic)
- Gripping Mechanism (e.g., friction or interlocking surfaces)
Comparison of Design Processes

The process involves selecting appropriate components based on their electrical characteristics, ensuring compatibility, and designing a circuit that meets the desired functionality. Simulation and testing are crucial steps to verify the circuit’s performance.The mechanical design process emphasizes geometric considerations, material selection, and force analysis. The design involves creating a functional mechanism that satisfies specific geometric constraints and force requirements.
Considerations include material strength, stiffness, and wear resistance. Prototyping and testing are also important to evaluate the mechanism’s performance and durability. Finite Element Analysis (FEA) might be employed for more complex designs to predict stress and strain distributions. The approach is more iterative and involves physical prototyping and adjustments.
