An XOR (Exclusive OR) gate is a digital logic gate that outputs true (1) only when the number of true inputs is odd. For two inputs, the output is high when the inputs are different. XOR gates can be constructed using basic logic gates or directly with transistors (BJT or MOSFET). Using transistors, we can design compact, efficient circuits for custom digital logic applications.

A traffic light control circuit using IC CD4017 is a simple digital electronics project that mimics the working of a real traffic light system. It uses the CD4017 decade counter IC along with a timer (usually 555 IC) to sequentially switch Red, Yellow, and Green LEDs, simulating the flow of traffic signals.

A Touch ON/OFF Switch is an electronic circuit that allows a device to be turned on or off by simply touching a sensor pad or wire, instead of using a mechanical switch. It works by detecting a small electrical signal from the human body (capacitive or resistive touch) and using that to toggle the output state.
These switches are commonly used in modern electronics, home automation, and DIY projects due to their durability, aesthetic appeal, and user-friendly operation.

A solar-based LED system is a lighting setup that uses solar energy to power LED (Light Emitting Diode) lights. During the day, a solar panel captures sunlight and converts it into electrical energy, which is stored in a battery. At night or in low-light conditions, this stored energy powers the LED light.
These systems are eco-friendly, cost-effective, and ideal for off-grid or outdoor applications like street lighting, garden lights, and emergency lighting.

A Security Alarm Circuit using the LM358 IC is a simple yet effective system designed to trigger an alarm when unauthorized access or movement is detected. The LM358, a dual operational amplifier (Op-Amp), is used as a comparator to detect voltage changes from sensors like LDRs, IR sensors, or switches, and then activate a buzzer or relay.

An OR gate using transistors is a basic logic circuit built using NPN transistors that performs the logical OR function. It gives a high output when at least one input is high. This is a fundamental building block in digital electronics and can be implemented using discrete components like transistors and resistors.

-
A NOR gate using transistors is a basic digital logic circuit that outputs HIGH (1) only when all inputs are LOW (0). It’s built by combining an OR gate followed by a NOT gate, using simple NPN transistors.
