Arduino Projects & Tutorials

An Arduino Board is AVR microcontroller based board which follows the standard arduino schematic and is flashed with the arduino boot-loader. The arduino is referred as open source hardware, since the standard schematic is open to everyone and anybody can make their own version of arduino board following the standard schematic. All arduino boards should be compatible with the arduino IDE which can be used to program the arduino boards. The arduino IDE is also open source and anybody can contribute their libraries to the arduino.

The arduino board has all the required circuitry to get the built-in AVR microcontroller running. The output or inputs can be taken from the boards or given to the board using convenient connectors. Both digital and analog inputs and outputs are available in all arduino boards. The arduino boards can also communicate with other devices using standard communication ports like USART, IIC, and USB etc. The most impressive thing is that most of the arduino boards are bread-board compatible which makes both the hobbyist and developers happy.

This section of EG Labs brings you some basic tutorials and interesting arduino projects based on Arduino Pro Mini Board. Explained with the help of circuit diagrams, source codes, and working videos, these arduino projects can serve as a good reference for final year electronics engineering projects.


Latest Arduino Projects

This is a project based on Arduino board which can measure the unknown resistance values and perform diode test and continuity testing. When we connect the unknown resistor on the breadboard circuit, the 16x2 LCD displays the resistor value and when we connect a diode the LCD displays the type of diode if it is a good one. When we take the probes out from the breadboard and connect it across a continuous path, the meter indicates the continuity by blinking an LED.

The project uses an Arduino pro mini board whose ADC feature is used along with the concept of Voltage Divider circuit to develop this Ohmmeter.


This a simple tutorial on how to setup your Arduino board with Ethernet shield to control your home appliances like Lights or Fans using any device (Mobile/Tablet/Laptop/Desktop) connected to your WiFi network. To get going you just need Arduino Ethernet Shield, Arduino UNO. Infact you can make use of any other Arduino board which is compatible with the Arduino Ethernet Shield. Besides this a Relay Board and a Wi FiRouter is required. So why wait pick up your kit and follow this step by step tutorial to contol your home appliances. Are you ready?  

The plotting of Data on a graph is used to observe, and subsequently describe, visible patterns that exist within the data. The main aim of this project is to show, how to plot a variable graph using processing environment and Arduino. In this article temperature is plotted on the processing graph. Processing environment is quite similar to Arduino but difference is in processing environment. We can plot the graph but in Arduino we can’t plot any type on graph. Processing Environment is very useful in cases of plotting Analog graphs.

Here we are going to discuss plotting temperature graph on computer or laptop using Processing Environment and Arduino. Circuit of reading temperature is very simple.
