In the era of Internet of Things (IoT), wireless communication is getting increasingly popular in everyday life. Nowadays, devices can talk to each other over the cloud or local network. When we talk about local wireless communication, we need an RF system module that executes these tasks, we see can find various RF system modules with various configurations like Bluetooth…
RFID (short for Radio Frequency Identification) tagging is an ID system that uses electromagnetic waves in radio frequency to transfer data. A simple RFID system consists of just two components: the tag itself and a read/write device. The read/write device consists of a Radio Frequency module and an antenna that generates a high-frequency electromagnetic field while the tag…
Motion detection is a common application for intruder alarms, light switches, and other home and industrial automation applications. And there are several ways to do it. We have already used a PIR sensor for motion detection, it senses the change in ambient infrared energy caused when a warm body enters the monitored area.
In this tutorial, we…
In industrial automation and control, PID controller has become one of the most reliable control algorithms that can be implemented to stabilize the output response of any system. PID stands for Proportional-Integral-Derivative. These three types of control mechanism are so combined that it produces an error signal, and this error signal is used as feedback to control the…
If you are a maker like me and looking for some interesting projects online, a milliohm meter is one easy and useful thing you can make. The basic principle of this circuit is based around a constant current source, which we have covered in one of our previous articles. A milliohm meter is a device that can be used to determine the values of small resistors, the resistance…
If you are an electronic enthusiast like me who wants to tweak around with different electronic circuits, having a decent Function Generator sometimes becomes mandatory. But owning one is a problem because such basic equipment can cost a fortune. Building your own test equipment is not only cheaper but also a great way to improve your knowledge.
So…
“Good morning. It’s 7 A.M. The weather in Malibu is 72 degrees…” these were the first words of JARVIS when being introduced in the Marvel Cinematics Universe. Most Iron Man fans should be able to recollect this scene and remember that JARVIS was able to open a window (kind-of) in the morning and give updates on time and weather. In the movie, the window Glasses were actually…
In this tutorial, we are going to talk about fuses. Back when I was in college and learning about all the cool things in electronics, I heard the term fuse in AVR for the first time, my initial thought on the topic was, oh! there is something inside the AVR that will blow if I did something wrong. Back then, there were not much resources available on the Internet…
ATtiny85 Microcontroller Chip is an affordable and powerful alternative to other Arduino microcontrollers, especially when you want to shrink your project down. The chip features 8 pins out of which six are I/O (Including Reset) pins and two are power pins. But how do you program it as it doesn’t have a USB interface like other microcontroller boards? So in this article…
In this tutorial, we are going to build an easy and cheap Pedometer using ATtiny85 IC, MPU6050 Accelerometer & Gyroscope, and OLED Display Module. This simple Arduino based step counter is powered by a 3V coin cell, making it easy to carry when you go out for a walk or jog. It also requires very few components to build and the code is also relatively simple. The program…
The ATtiny family is a series of one of the smallest microcontrollers in the AVR market. These microcontrollers are capable of utilizing many of the libraries available on the Arduino platform. The ATtiny85 microcontroller chip is 8-pin, 8-bit, AVR microcontroller. Its small size and low power consumption make it a great match for portable projects with small footprints and…
An electronic scoreboard is one of the most important gadgets anybody can have during any sports tournament. Old manual scoreboard using conventional methods are very time consuming and Error-prone, hence a computerized scoreboard becomes necessary where the display unit needs to be changed in real-time. This is why in this project, we will be building a Bluetooth…
