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. ...

What is AM2301 Sensor? The AM2301 module is an internally-calibrated digital sensor that measures temperature and humidity. It can measure humidity from 0 to 99.9% with an accuracy of ±2% and temperatures from -40 to 80°C with an accuracy of ±3°C.This digital module uses a single-wire protocol for communication. So, apart from the power supply pins, it only needs one digital pin to communicate with the microcontroller. Using this protocol, we can transfer data through this line for a maximum distanc...

ZMCT102W Features The ZMCT102 transformer has a turns ratio of 2000:1, a maximum input current of 5A, and a maximum output current of 2.5mA. In addition, the hole in the transformer, through which the wire passes, has an inner diameter of 5mm.ZMCT102 transformer measures the current based on the magnetic field generated by the current flowing through the wire at the center of the transformer. It then provides an output voltage value that is proportional to the current.In this tutorial, we will cover t...

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...

Installing New Library in PlatformIO, Step 2: Finding Library Location Using ...

Introduction The KY-028 module contains a thermistor sensor that measures the ambient temperature. The resistance of the thermistor varies inversely with temperature. In addition, the analog and digital output pins provide the sensor's data. When the value measured by the sensor exceeds the threshold, the digital pin goes HIGH, lighting up the LED on the module. Tip You can adjust the digital output threshold using the blue potentiometer on the module. KY-028 Pi...
