High-Output Pulsed-Tone/Light-Activated Alarm Circuit
This circuit is capable of generating up to 1 W of audio power to drive a speaker or horn. When the CDS cell is exposed to light, its resistance decreases, activating NOR gate (a). This activation causes gates (a) and...
5 Zone Alarm Circuit
Each zone uses a normally closed contact. These can be micro switches or standard alarm contacts (usually reed switches). Zone 1 is a timed zone which must be used as the entry and exit point of the building. Zones 2...
Security Monitor
This circuit can be utilized in a garden setting to detect unusual sounds or wildlife noises. It can also monitor sounds around a car parked in a remote location. The cable used for the setup can either be visible or...
Motion Detector Sensor Circuit
This circuit is a motion detection sensor that utilizes a light source and detector as an infrared motion detector. It incorporates components such as a light-emitting diode (LED), a phototransistor, a transmitter, a receiver, an NE555 timer configured as an...
Intruder Alarm
This is a simple single-zone burglar alarm circuit. Its features include automatic Exit and Entry delays and a timed Bell/Siren Cut-Off. It's easy to use. First check that the building is secure and that the green LED is lit. Then...
Motion Activated Camera
A straightforward attachment for a Canon SLR camera designed to create a motion-activated camera using an Arduino. This project draws inspiration from the intervalometer project at The Honey Jar, with modifications made to the circuit by utilizing a 4N35 optocoupler...
Electronic Watchdog
The electronic watchdog circuit functions similarly to a traditional guard dog, monitoring a 10-meter area around a door. When someone enters this monitored zone, the circuit emits a realistic barking sound. This sound can be sustained for 10 seconds, and...
Automatic Room light Control With Bi Directional Visitor Counter
The objective of this project is to create a controller-based model that counts the number of individuals entering a specific room and activates the lighting accordingly. This is achieved through the use of sensors that detect the current number of...
Gate automatic lamp circuit
The circuit utilizes multiple integrated circuits to form an automatic lighting device that is activated by door and window sensors. It includes CD4093 digital integrated circuits, a relay, and a power supply circuit. The system typically remains closed when a...
