basic cds photocell detector
This is a basic Cadmium Sulfide (CdS) photocell detector circuit. In this circuit, when light falling on the photocell (PC1) is blocked, its resistance increases, causing the voltage across PC1 to rise. When the voltage exceeds half of the supply...
Light Follower Robot
The figures above illustrate the fundamental concept of a robot, which consists of various input and output devices connected to a central processing unit, commonly referred to as the brain. These inputs and outputs are essential for the robot's functionality...
home-made light-operated camera trigger
This device is designed to capture images of moving objects by activating a camera or flashgun when one or two light beams are interrupted. Originally intended for photographing insects in flight, it can also be utilized for projectiles and other...
sun up alarm schematics
The Up Alarm is designed to provide an audible alert when sunlight is detected or when a light source is activated in a dark environment. It can also be utilized to sense various light sources such as beams or headlights....

Super Light Sensor
This Super Light Sensor responds to minute fluctuations in light levels, automatically adjusting from approximately 200 lux to 60,000 lux (from a modestly lit room to direct sunlight). It has various potential applications, such as detecting a car entering a...
Optical tracking control circuit
The photocell photoelectric tracking circuit is configured with two identical photoelectric cells that serve as light-receiving devices. When the incident light intensity is equal, the system is able to track in a predetermined manner. If there is a slight deviation...
Light-Controlled Oscillator Circuit
This circuit can be utilized as a light detector and potentially as a tool for individuals with visual impairments. The frequency of the oscillator is influenced by the level of illumination received by LDR4.
The circuit operates by employing a Light...
