The Iconic name “Nokia 5110” itself should have bought memories of the robust Nokia mobile phone which was very popular during the 90’s. The model 5110 came with a Graphical Display which was sufficient enough to act as a display screen for the mobile back then. This screen was capable of displaying everything from alphanumeric characters to small graphics that is everything…
In today’s modern world, where ever we go we have lots of electronic devices around us. But, out of all, there is only one device that we personally have in our pockets all the time. Yes, it is our mobile phones. Now Mobile phones have become more than a device used for communication, they are our cameras, they are our maps, they are our shopping karts and what not?

Sensors have always been a vital component in any Project. These are the ones which convert the real real-time environmental data into digital/variable data so that it can be processed by electronics. There are many different types of sensors available in the market and you can select one based on your requirements. In this project we will learn how to use a Hall sensor a.k.…
In this project we control direction and speed of a 24v high current motor using Arduino and two relays. No power switches are needed for this circuit, just two push buttons and in Potentiometer to control the direction and speed of DC Motor. One push button will rotate motor clockwise and other will rotate it counter clockwise. One n-channel MOSFET is required to…
Recently Gesture controlled Laptops or computers are getting very famous. This technique is called Leap motion which enables us to control certain functions on our computer/Laptop by simply waving our hand in front of it. It is very cool and fun to do it, but these laptops are really priced very high. So in this project let us try building our own Gesture control Laptop/…
In today’s modern world we all depend on mobile phones as our primary means of wireless communication. But, we all have faced situations during which we might not be able to answer to our calls, these calls might be an important personal call or a life changing business call and you could have just missed that opportunity since you were not able to answer that call at that…
In our previous tutorial we learnt how to install python on our windows machine and how to interface Arduino with python using a simple LED control project. If you are new, I would strongly recommend you to fall back to the previous tutorial since this tutorial is a continuation of the same.
You might have already started to wonder why we would need…
Automatic floor cleaners are nothing new, but they all share a common problem. They all are too expensive for what they do. Today, we will make a Automatic Home cleaning Robot that only costs a small fraction of the ones in the market. This Robot can detect the obstacles & objects in front of it and can continue moving, avoiding the obstacles, until the whole room is…
Ammeter is used to measure current flow through any load or device. Here in this Arduino Ammeter, we will explain about measuring of current by using ohm’s law. It will be quite interesting as well as a good application of basic science that we studied in our school days.
All of us are well known of ohm’s law, It states that “the potential…
In this project we are going to make a Buck Converter Circuit using Arduino and N-Channel MOSFET with a maximum current capacity of 6 amps. We are going to step down 12v DC to any value between 0 and 10v DC. We can control the output voltage value by rotating the potentiometer.
A buck converter is a DC to DC converter, which steps down DC voltage.…
With a simple knowledge of Arduino and Voltage Divider Circuit, we can turn the Arduino into Digital Voltmeter and can measure the input voltage using Arduino and a 16x2 LCD display.
Arduino has several analog input pins that connect to an Analog-to-Digital converter (ADC) inside the Arduino. The Arduino ADC is a ten-bit converter, means that the…
CNC Machines are Computerized Numerical Control Machines which are used to draw anything or design any mechanical part according to the design program fed into their controller unit. Controller unit can be either computer or microcontroller. CNC machines have stepper and servo motors to draw the design as per the fed program.
After researching on…
