In this tutorial will learn how to interface ADC0804(Analog to Digital Converter) with 8051(89c51,89c52) microcontroller. 8051 microcontrollers are pretty old and don’t have a build in analog to digital converter in them unlike their new rivals(Arduino, Pic microcontroller and many more). Hence we can not directly measure any analog value (voltage, Temperature present in the

A China-based manufacturer called RAK Wireless has released the RAK833 LoRaWAN gateway module a couple months back. This has already been used hugely to create a gateway for ‘The Things Network’. Now they’re back with the new RAK8213, an NB-IoT and LTE Cat M1 module in the same mini-PCIe form factor as the RAK833. The RAK mini-PCIe card is constructed

Weather monitoring systems are available in plenty and these are pretty handy gadgets we use in our daily life for weather forecasting and other purposes. But these kinda gadgets might be expensive and may not be available for customization to our specified purpose. To overcome these advantages you can build this customized weather meter using

This project is about building a microcontroller-based digital room thermometer plus hygrometer that displays temperature and relative humidity on 4 large (1 inch) seven segment LED displays which adjust their brightness level according to the surrounding illumination. It consists of a closed loop system that continuously assesses ambient light condition using an inexpensive light-dependent resistor
Capacitors are one of the most common passive electrical components that are extensively used in all kinds of electronic circuits. In this project, we will discuss a technique of building a digital capacitance meter using a PIC microcontroller. This project can measure capacitance values from 1 nF to 99 ?F, with a resolution of 1

An article by Dieter Laues in the February 2012 issue of Elektor inspired me to get my soldering iron out. The article described how by measuring the frequency of the mains electricity supply in any socket, the relative load across the entire electricity network could be determined. I ordered a pre-programmed processor (of the correct

I recently bought a 500ppm LCR meter from Elektor because I didn’t have anything for measuring inductors or the ESR (equivalent series resistance) of capacitors, both of which are important for modern electronics, particularly switch mode regulators that have become ubiquitous. It is also more accurate than any of my multimeters and has wider measurement

The Internet-of-Things Power Meter (IPM) is a device fixed on top of the regular household power meter that provides detailed information about the electricity usage. Modern power meters have a LED blinking every time a Watt is used, the IPM detects these flashes using a light sensor, counts them, saves the values to an SD
