An AC Current Detector is a device or circuit that senses the flow of alternating current (AC) through a wire or appliance. It typically uses components like a current transformer (CT) or hall effect sensor to detect AC current and activate an indicator such as an LED or buzzer.

An AND gate can be built using BC547 NPN transistors, a common general-purpose transistor used in digital circuits.
The circuit represents both the inputs A & B for the AND gate and Output, Q, which also has a +5V supply to the collector of the first transistor, which is connected in series to the second transistor, and an LED is connected to the emitter terminal of the second transistor. The inputs A & B are connected to the base terminal of Transistor 1 and Transistor 2, respectively, and the output Q goes to the positive terminal LED.

An Automatic Street Light using the IC 555 is a simple circuit that turns street lights ON at night and OFF during the day automatically. It uses a Light Dependent Resistor (LDR) to detect ambient light and a 555 Timer IC configured in comparator mode to control the switching.

A Battery High-Low Monitor is an electronic circuit or device that detects and indicates the voltage level of a battery — whether it’s too high (overcharged), normal, or too low (discharged). It helps protect batteries from overcharging or deep discharge, which can damage the battery or reduce its lifespan.
These monitors often use comparators, voltage dividers, LED indicators, or microcontrollers to track and display battery status in real time.

A Bicycle Direction Indicator is a safety system that uses LEDs or blinkers to signal the rider’s left or right turn intentions, just like car indicators. It’s often controlled by push buttons, switches, or microcontrollers.

A Bird Bell is a device designed to either attract, entertain, or repel birds, depending on its purpose and context. Traditionally, it is a small bell-shaped object made of metal, ceramic, or wood, and is usually hung in gardens, balconies, farms, or near bird feeders. Its name comes from its interaction with birds — it may ring when birds land on it, brush past it, or when the wind causes it to move.

An Electronic Coin Toss circuit is an electronic version of the classic coin flip — often used to make quick decisions, settle disputes, or play games. It mimics the randomness of a real coin toss using digital logic or a microcontroller to generate a pseudo-random result and display it using LEDs or a text display (e.g., “Heads” or “Tails”).

The Electronic Coin Toss is a simple, fun, and educational project that replaces a physical coin with digital logic or microcontroller-based randomness. It’s ideal for learning basic electronics, understanding random number generation, and creating a useful and entertaining tool.

An Electronic Dice is a digital version of a traditional dice, which generates a random number (1 to 6) and displays it using LEDs or a 7-segment display. It uses components like a 555 timer, counter IC (like CD4017), or microcontrollers such as Arduino to simulate dice rolls electronically.

A Fire Detector Alarm is an electronic system designed to detect the presence of fire or high heat and trigger an audible or visual alarm. It typically uses sensors like thermistors, temperature sensors, or flame sensors to detect abnormal conditions indicating fire.

A Flip-Flop LED Flasher is a simple electronic circuit that alternately turns two LEDs on and off in a continuous loop, creating a blinking or “flashing” effect. It’s commonly built using transistors, resistors, capacitors, and LEDs, forming an astable multivibrator — a basic circuit that oscillates between two states without any external triggering.
It’s often used for decoration, indicators, or learning basic electronics.

A Hall Effect Alarm is a type of security or position-detection system that uses a Hall Effect sensor to detect the presence or movement of a magnet. When the magnetic field changes (such as a magnet being removed or moved), the circuit triggers an alarm (buzzer, LED, relay, etc.).
