In StockAn 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.
Description
An Automatic Street Light system eliminates the need for manual operation of outdoor lighting. The system is built around the popular 555 Timer IC, configured to work as a comparator. It detects the change in ambient light using an LDR (Light Dependent Resistor) and switches the light ON or OFF accordingly.
During daylight, the resistance of the LDR is low, and the 555 IC output remains LOW, keeping the light OFF. At night, the resistance increases significantly, causing the 555 output to go HIGH, turning the light ON through a transistor switch or relay.
Applications:
1.Street Lighting Automation
1.Turns street lights ON automatically at night.
2.Garden and Outdoor Lights
1.Activates decorative or security lights in low light.
3.Security Systems
1.Automatically lights up pathways or entrances in the dark.
4.Energy Saving Systems
1.Reduces power wastage by ensuring lights operate only when needed.
5.Solar Lighting Projects
1.Integrates well with solar panels for automatic dusk-to-dawn lighting.

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”).

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.

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 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.
