In this tutorial, we will show you how to control DC motor using MATLB and Arduino. If you are new with MATLAB then it is recommend to get started with simple LED blink program with MATLAB.

 

Creating MATLAB Graphical User Interface for controlling DC Motor

After finishing setup with Arduino for MATLAB, we have to…

I recently purchased the Neo Pixel LED strip and was quite impressed by the way it works. The tiny LED’s have an inbuilt driver IC which helps us to control each LED individually and can produce a wide spectrum of colors. Being a garish person who is obsessed with colours I really loved watching these tiny LED’s changing colors so I decided to build something on my own and…

While Internet of things (IoT), Industry 4.0, Machine to Machine communication etc are getting increasingly popular the need for wireless communication has become incumbent, with more machines/devices to speak with one another on the cloud. Designers use many wireless communication systems like  Bluetooth Low Energy (BLE 4.0), Zigbee, ESP43 Wi-Fi Modules, 433MHz RF…

Health monitoring is the major problem in today’s world. Due to lack of proper health monitoring, patient suffer from serious health issues. There are lots of IoT devices now days to monitor the health of patient over internet. Health experts are also taking advantage of these smart devices to keep an eye on their patients. With tons of new healthcare technology start-ups,…

Hi guys, during the last few weeks, I’ve been working on reconnecting with my love for the guitar. Playing the box guitar was how I relax few years back before the saxophone took over. Going back to the guitar, after 3 years of rarely strumming a chord, I discovered amongst other things that I no longer knew how each of the string should sound, to put it in my friend’s words…

Measuring the speed/rpm of a Vehicle or a motor has always been a fascinating project to try. In this project, we are going to build a Analog Speedometer using the Arduino. We will use IR Sensor module to measure the speed. There are other ways/sensors for this, like hall sensor to measure speed, but using an IR sensor is easy because IR sensor module is very common device…

All embedded lovers are familiar with multimeter which a great tool to measure voltage, current, resistance etc. A multimeter can measure them easily. But sometimes we need to measure inductance and capacitance which is not possible with a normal multimeter. There are some special multimeters that can measure inductance and capacitance but they are costly. We already built…

As electronics engineers, we always depend upon meters/instruments to measure and analyse the working of a circuit. Starting with a simple multimeter to a complex power quality analysers or DSOs everything has their own unique applications. Most of these meters are readily available and can be purchased based on the parameters to be measured and their accuracy. But sometimes…

After being inspired by RYNO motors and other self-balancing scooters from Segway, I always wanted to build something of my own Arduino Segway Robot. Thinking for a while, I decided to build a Self Balancing Robot using Arduino. This way I would be able to grasp the underlying concept behind all these scooters and also learn how the PID algorithm works.

Although Raspberry Pi and Arduino are two different hardware in terms of their applications and structure, but they both are considered as two competing open source hardware platforms. They both have very strong community and support. Today we will slightly change things, and show you how we can take advantage of both of them. If you have both Arduino and…

The Oscilloscope is one of the most important tools you will find on the workbench of any electronics engineer or maker. It is primarily used for viewing waveform and determining voltage levels, frequency, noise and other parameters of signals applied at its input that might change over time. It is also used by embedded software developers for code debugging and technicians…

This tutorial describes how to make an automatic water dispenser from Arduino and an ultrasonic sensor. This tutorial describes how to make an automatic water dispenser using an electronic diagram, a code snippet, a list of things, and a demonstration of how to make your water dispenser work.
