This is a project circuit which helps to a person in the driving seat and gives an alarm if there is any obstacle or a wall while parking or while driving in reverse. This is a project circuit which ...

This infrared detector circuit uses a passive IR-detector component PID20. It converts heat radiation into electrical impulses. The output voltage of the PID20 increases when an object comes close to ...

How transimpedance amplifiers are used in fiber-optic communications, laser rangefinders, and LiDAR systems. How avalanche photodiodes enhance TIA performance. Application-specific design and topology ...

Many robotic applications require a sensor to detect close or very close obstacles. Typically, reflective-type infrared sensors are used for this task. But the circuit in the figure shows an infrared ...

Circuit sculpture is a great way to elevate your soldering and electronics skills to the realm of three-dimensional art. In this case, art can be practical, too. Take [romaindurocher]’s interactive ...
