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 […]

Sending a Tweet by Waving your hand
In this tutorial, we will be using a PIR Motion Sensor and a NodeMCU to send a custom tweet when you wave your hand. I have already made a tutorial on PIR Motion Sensors to refer to : PIR Motion. Without any delay, lets jump in! Things Required Twitter Account NodeMCU Jumper Wires PIR Motion […]
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 Processing PDE – Tutorial 2
Today, let us have a look at more functions and code examples. Before Tutorial 2 on Processing, please have a look at the first tutorial : Tutorial 1 Color Me This code will color the “Hi Sau” text blue as soon as you roll over your mouse in that area. Let us have a look […]
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 SD Card Reader with Arduino
This post is about how to use the Micro SD Card Reader with the Arduino. This will allow you to store the relevant data into a Micro SD Card. We’ll also be discussing how a Micro SD Card works. Micro SD Card Micro SD Cards or Secure Digital works on Flash Memory ( Click here […]
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 […]
