Since Internet of Things (IoT) projects are now quite popular, I recently bought a NodeMCU board to try IoT application development. The NodeMCU development board is an open source board based on ESP8266EX microcontroller with integrated Wi-Fi transceiver. Uploading programs to NodeMCU from any computer via microUSB port is very easy as it supports several

A digital soil moisture meter is used for indicating the water content of a given soil sample. As crop production requires water at different stages and in different amounts, it is important to measure soil moisture from time to time to know its status. The digital soil moisture meter circuit presented here, for monitoring the

Presented here is an ATmega328P microcontroller-based ultra low power sensor hub using nRF24L01+ radio frequency (RF) transceiver modules having transmitter and receiver units. The transmitter sends humidity and temperature values of a place to the receiver kept at a remote location for display on an OLED module. The nRF24L01+ module used in the receiver unit

Microcontroller based miniscule event counter presented here is based on the inexpensive Digispark Attiny development board. One advantage of this design is that any type of active or passive switch can be connected to its trigger input. Whenever the switch closes event will be counted inside the microcontroller and would be displayed on the 4-digit

Nowadays numerous electronic devices make use of vibrotactile feedback to increase user interaction with the help of suitable haptic feedback hardware like the eccentric rotating mass motors, linear resonant actuators, and piezoelectric actuators. The most popular type of eccentric rotating mass (ERM) motor inside of consumer electronic devices is the pancake vibration motor (coin vibration

This article shows you how to build a small radio station at home and share music with others. The station can also be used for making announcements in colleges, industries, hospitals, schools and other places using a condenser mic amplifier circuit. In this project an FM transmitter V2.0 module is used, as shown in Fig.

Precise measurement of line signal frequency is very important in many applications, especially in the management of power grid systems. Tasks like calibration of governors of engines that run generators in power plants need a resolution up to 0.01Hz. Frequency is also an important parameter in load sharing among several power plants in the grid.
