Interfacing RDM6300 RFID Reader Module with Arduino Interfacing RDM6300 RFID Reader Module with Arduino

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…

Interfacing RCWL-0516 Doppler Radar Sensor with Arduino Interfacing RCWL-0516 Doppler Radar Sensor with Arduino

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…

Arduino Based Encoder Motor Controller Design an Arduino Based Encoder Motor using PID Controller

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…

Arduino Based Low Resistance Meter Build Your Very Own Low Resistance Meter with Arduino

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…

AD9833 and Arduino Based Function Generator Build your own Function Generator with Arduino and AD9833 DDS Function Generator Module

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…

Arduino based Window Blinds Controller Arduino based Roller Blinds to Automate and Control your Window Curtains with Google Assistant

“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…

Fuse Bits in ATmega328P AVR Microcontroller Understanding Fuse Bits in ATmega328P to Enhance Arduino Programming Efficiency

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…

Programming ATtiny85 with Arduino Uno Programming ATtiny85 Microcontroller IC with Arduino Uno

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…

Portable Step Counter Using ATtiny85 and MPU6050 Build a Portable Step Counter using ATtiny85 and MPU6050

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…

Programming ATtiny85 IC directly through USB without Arduino using Digispark Bootloader Programming ATtiny85 IC directly through USB using Digispark Bootloader

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…

Arduino LED Score Board Build an Arduino Scoreboard using Outdoor P10 LED Matrix Display and Update Scores Remotely using Smartphone

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…

Measuring CO2 Concentration in Air using Arduino and MQ-135 Sensor  Measuring CO2 Concentration in Air using Arduino and MQ-135 Sensor

The earth’s Atmospheric CO2 level is increasing day by day. The global average atmospheric carbon dioxide in 2019 was 409.8 parts per million and in October-2020 it is 411.29. Carbon dioxide is a key greenhouse gas and responsible for about three-quarters of emissions. So CO2 level monitoring has also started to gain importance.

In our previous…
