LED Blinking: We use an LED (Light Emitting Diode), which is connected to the Arduino via a resistor. The resistor limits the current that flows through the LED to prevent it from burning by too much ...

ACS712 Current Sensor with Arduino The ACS712 is a popular Hall-effect-based current sensor that provides accurate current measurements in both AC and DC circuits. It is widely used in electronic ...

In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

The title says it all – this article describes a microcontroller-compatible current sensor module you can build yourself, using an inexpensive 8-pin chip as an ‘active shunt’ for measuring ac/dc ...

The topmost part of the PIR sensor consists of a lens with concentric grooves carved into the plastic. These are called Fresnel lens. The contours on this plastic helps in gathering parallel light ...
