Introduction DS3231 is a low-cost , accurate I2C real-time clock ( RTC ) which keeps track of time. RTCs are present in almost any electronic device which needs to keep accurate time. It should not be confused with hardware clocks which are signals that oscillate between a high and a low state. RTCs have an […]

Guide for Dust Sensor with Arduino
GP2Y1010AU0F or Sharp PM2.5 Dust Sensor consists of an Infrared Emitting Diode and Phototransistor ( which we are going to discuss shortly ) which detects the reflected light of dust in air and is efficient in detecting fine particles. It is compact with low consumption current ( max of 20mA ). It is commonly used […]
Guide For Using Capacitive Touch Sensor with Processing
In this Tutorial, we will be learning how to use Capacitive Touch Sensor and its integration with Processing. If you are new to Processing, have a look at my previous Processing Tutorials from scratch : Processing – Tutorial 1 Processing – Tutorial 2 Introduction TTP223 Capacitive Sensor is a low-cost device. When you touch the […]
Guide for PS2 Style Joystick
A PS2 Style Joystick is very similar to PS2 controllers and is a thumb operated device. There are 2 potentiometers ( one for each axis and of 10k each ). It even includes a select button which can be pressed. In this tutorial, we will be using a 2-axis joystick module. Parts Required 1 x […]
Guide for ADXL335 Accelerometer with Arduino
ADXL335 Accelerometer measures acceleration or responds to acceleration, detecting when something starts to move or stop. It can even detect how something is oriented with respect to the Earth’s surface. They come in various types and different number of axes they can sense. Here, we’ll be using 3 axes accelerometer, sensing acceleration in all three […]
Guide for using RFID Module with Arduino
Radio Frequency Identification or RFID is a wireless system that uses electromagnetic fields to transmit data from one object to another, without the two objects touching. You might have used RFID cards before or seen its implementation ( Ex- Metro Stations ). There are various kinds of RFID tags available like the one shown below. […]
Memories of an Arduino
“Computers are incredibly fast, accurate and stupid; humans are incredibly slow, inaccurate and brilliant; together they are powerful beyond imagination” There are 3 types of memories in an Arduino : Flash SRAM EEPROM Flash Memory It is where the Arduino sketch image is stored. Non-Volatile , i.e. , information persists after the power is turned […]
