Introduction There are different sensors and methods for determining water depth, leakage, whether a container is empty or overflowing, and rain detection. One of the easiest and cheapest methods is to use a water level detection sensor that we will discuss in this tutorial.There are some other common names for this sensor: rain sensor, water level sensor, humidity sensor, and water leakage sensor. What you will learn Operating principles of a water level sensor and how to test itInterfacing th...

Overview Power outages are one of the main problems for computers and electrical systems. Sometimes there is data and information in your system that you do not want to be deleted with a power outage. If you do not want your data and information to be lost when the power supply is disconnected, a simple way is to save your data to EEPROM memory.In some projects, such as a 3D printer, when the system is reset, the relevant data can be stored in EEPROM memory to calibrate the equipment and initialize it. ...

Overview A potentiometer is a device that can change its resistance by moving a contact along a fixed resistor. It has three terminals: one connected to each end of the resistor and one connected to the movable contact. By adjusting the position of the contact, the potentiometer can divide the input voltage into different output voltages [Read more in Wikipedia]. Potentiometers work by creating a voltage drop across the resistor that is proportional to its length. For example, if the input voltage is 10...
