IoT_Photoresistor-LDR_using_Arduino Light-dependent resistors (also known as photoresistors, photocells, or LDRs) are sensors that decrease their resistance as the amount of light that they’re exposed ...

LDR SENSOR is nothing but a light-dependent resistor, its resistance changes according to changes in light intensity. In this blog we will discuss what LDR SENSOR is and how it can be used with the ...

The junction on the voltage divider network connected to the the Arduino analog pin is equivalent to the input voltage divided by 11, so 55V ÷ 11 = 5V. In other words, when measuring 55V, the Arduino ...

Much to the chagrin of hardware tinkerers, the Raspberry Pi doesn’t have analog inputs on its GPIO pins. Sure, you can blink a LED with just a few console commands, but reading sensors with a… ...

2-Axis analog Joystick The connection of Arduino controller to joystick sensors and button is very simple as shown in the layout diagram. As stated, The joystick can be moved in two dimensions ...
