Stepper motors are crucial components in the robotics and automation industry, and Arduino stepper motor controllers have made these motors accessible and affordable for beginners and professionals alike. The benefits of using Arduino are numerous, including easy programming, versatility, accurate positioning, and affordability.
Building a remote relay switch DIY circuit using CD4017 IC and IR receiver is an excellent way to make your home smarter and more convenient. With this circuit, you can control electrical devices from a distance, save energy, and improve safety in your home. The process of building this circuit is easy and requires only a few basic components.
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.
The 12V-Battery Low Volt Disconnect Circuit using LM358 IC and IRFZ44 MOSFET is an excellent solution to prevent your battery from getting completely discharged. The circuit is straightforward, and the components used are easily available. By using this circuit, you can protect your batteries from permanent damage and prolong its lifespan.
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.
