The battery over current protector circuit using 555 TIMER IC and BC547 transistors is an essential circuit to protect your battery-operated devices from potential hazards. The circuit’s primary objective is to detect when the battery is subjected to over-current and shut off the current flow instantly.
How to make voice controlled light using Arduino and an android phone. I have tried to make this video as easy as it can be. The relay board I used in this video, is home made. You find its DIY video link in the component’s List below. You can use any relay board instead.
The Infrared Receiver is designed to work together with the infra-red transmitter mentioned in the previous post, to create a complete infra-red remote control system. Instead of coding and decoding, the transmitter’s carrier is altered in a simple way to produce consistent switching signals. The receiver module is set to switch from low to high when the carrier signal is received for over 200 milliseconds.
The Infrared IR Transmitter is intended primarily for the testing of infrared receivers. The test is possible in most cases even without having the associated remote control available. Of course, the test will then be limited to just the infra-red sensor device in the receiver, but it is very useful to begin with when it comes to faultfinding in an infra-red controlled system like a TV set or a VCR.
The diagram illustrates a sensor/monitor that activates the host system upon detecting IR signals. It is designed to use a minimal amount of supply current, making it suitable for continuous usage in devices such as laptops and PDAs.
The Mains Fuse Failure Indicator is a crucial device for ensuring the safety of electrical circuits. It serves as a warning signal when the main fuse fails, and helps protect equipment from potential damage caused by electrical faults.
The spark plug monitor circuit is a useful tool for vehicle maintenance. It helps in diagnosing problems with the spark plugs and enables timely repairs, thereby ensuring smooth functioning of the engine. Regular use of this circuit can prolong the life of the engine and improve its performance.
The IR intruder alarm circuit is a highly effective and reliable device for securing and protecting properties against intruders. With its infrared-based motion detection technology, it can detect even the slightest movement and trigger an alarm, notifying the residents of any potential threats to their property.
The Crystal Frequency Multiplier using the ICS501M IC is a high-performance device that allows multiplication of input signals up to 160MHz. It provides low jitter and low phase noise, making it suitable for a wide range of applications such as communication systems, audio processing systems, and testing and measurement equipment.
Introduction Infra-red proximity detector circuit is one of the most popular gadgets these days. This circuit uses an LM567 IC that is specifically designed to detect the presence of infra-red rays. This technology is extensively used in various security systems, automatic door openers, and household gadgets to sense nearby objects. The detector is intended for […]
