A Transistor Tester is an essential electronic device used to evaluate the functionality of transistors. It can identify transistor types (NPN or PNP), measure their gain (hFE), and test their various pins to ensure proper connections. The tester typically features an easy-to-read display and controls that allow users to input the transistor’s pins for measurement. By applying a small test current, the device checks the transistor’s switching and amplification properties, providing valuable information about its health and performance. This tool is crucial for electronics enthusiasts and technicians for diagnosing and repairing electronic circuits.

The AND OR Gate project explores two fundamental logic gates: the AND gate and the OR gate.

• AND Gate: Outputs true only when all its inputs are true. For example, with two inputs, the output is high (1) only if both inputs are high (1).
• OR Gate: Outputs true if at least one of its inputs is true. For instance, with two inputs, the output is high (1) if either input is high (1), or both are high.

In this project, you’ll construct circuits using these gates to understand their behavior and interactions. By experimenting with different input combinations and observing the outputs, you’ll gain insights into basic digital logic and how these gates can be combined to form complex logic functions.
