ARDUINO MEGA 2560 REV3 The MEGA 2560 is designed for more complex projects. With 54 digital I/O pins, 16 analog inputs and a larger space for your sketch it is the recommended board for 3D printers and robotics projects. This gives your projects plenty of room and opportunities. Microcontroller ATmega2560 Operating Voltage 5V Input Voltage […]

Making a program start using a switch
Connecting the Switch To connect the switch to the Arduino, you will need the switch, two jumper wires, and a 10kΩ (brown-black-orange) resistor. Once you have all the required parts, you will need to wire the switch to the Arduino using the breadboard. NOTE: The virtual board may be slightly different from the physical one. […]
how to measure home ac current 110v / 200v with arduino
The cool thing about an ACS712 is that current is measured is measured in two directions. What this means is that if we sample fast enough and long enough, we sure to find the peak in one direction and the peak in another direction. With both peaks known, it is a matter of knowing the […]
LEARN! ARDUINO – A HANDS-ON APPROACH
INTRODUCTION This manual will show you how to use each of the components in the kit, and give you software Sketch examples for each one. Then you can combine some components to make examples of Automatic Systems such as a lighting controller. You’re probably here because you’re interested in MAKING things with Arduino. The […]
Line Frequency Meter Based On Reciprocal Counting
Precise measurement of line signal frequency is very important in many applications, especially in the management of power grid systems. Tasks like calibration of governors of engines that run generators in power plants need a resolution up to 0.01Hz. Frequency is also an important parameter in load sharing among several power plants in the grid. […]
L.O.G. $10 Arduino
There are probably thousands of articles on making an Arduino. So who needs another Arduino? Well, this Lazy Old Geek(L.O.G.) needs one. Here’s the features I would like: Features: Low cost More permanent than a breadboard Not a custom PCB More prototyping area than a RBBB or Anarduino or Boarduino Easier prototyping than just perfboards […]
IR Controller for Air Conditioner
Hardware components: Atmel ATTiny85 × 1 Everything ESP ESP8266 ESP-01 × 1 Arduino Nano R3 × 1 STORY My goal is to make my window AC units more functional. Currently they use an on-board thermostat to turn on when the room gets above a certain temperature (‘duh). I feel like there is a lot […]

Interfacing EM-18 RFID reader with Arduino Uno
Arduino Uno is an opensource physical computing platform based on ATmega328 microcontroller and provides a development environment for writing software for the board. It can be used for a variety of projects. EM-18 RFID reader is one of the commonly used RFID reader to read 125KHz tags. It features low cost, low power consumption, small form […]
Interfacing LCD with Arduino Uno
16×2 character LCD display is a very basic LCD module which is commonly used in electronic projects. 16×2 means it can display 2 rows of 16 characters (columns). Its other variants such as 16×1, 16×4 etc are also available. These LCDs are usually made using HD44870 compatible controllers. In this tutorial we will see how […]
