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 ...

In this article, we implement a rain and ice sensor by analyzing the reflection of an infrared (IR) light source. This project uses proven techniques based on multiple reflections of IR light in the ...

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 ...

We’ve all been there. Your current project has hit a wall, or the next step will take days to complete, and you need something to do in the meantime. So you start a project that you envision will fit ...

The LM358N is an operational amplifier or comparator which can be used to evaluate the voltage readings from the photosensors. It is one of the most important parts in an IR sensor circuit. The L293D ...
