Knowing the amount of water in an overhead tank can be one tedious task. Usually, you’ll end up climbing up the stairs to the tank and checking the level manually or you’ll you hear the water overflowing from the top. But these days electronic water level indicators are available to fix this problem, but they often come […]

How to make a Smart Cane for the Visually Impaired with Arduino
I wanted to make something for them to help the visually impaired become independent, so I created an open source Arduino project for a Smart Cane. This Arduino smart cane can assist with walking alone in new environments by taking inputs through an obstacle sensor (ultrasonic sensor) and providing feedback to the person through haptics […]
How to Make a Programmable Guitar Pedal With Arduino!
This DIY Guitar Pedal project is for guitarists, hackers, and programmers that want to learn about digital signal processing, effects, synthesizers, and experiment without deep knowledge of DSP, electronics, or hardcore programming. pedalSHIELD UNO is a lo-fi, programmable guitar pedal that works with the Arduino UNO/Genuino UNO boards and is Open Source & Open Hardware. […]
ESP8266 Tutorial: How to Control Anything From the Internet!
In this ESP8266 tutorial, we are using an ESP-01 module to control an LED over the internet. The ESP8266 is a very cheap yet really effective platform for communicating over the internet. It is also easy to use with an Arduino. After going through this ESP8266 tutorial, you will have the know-how to control any electrical device […]
DIY Arduino Tutorial: How to Automate a Lamp for Ceremonial Inaugurations
“Knowledge removes ignorance, just as light removes darkness”, as it is wisely said. In India, the ancient tradition of lighting oil lamps has a special significance. Almost all auspicious ceremonies are commenced by lighting a lamp. Hence came the idea to merge our traditional culture with the digital world using this DIY Arduino Lamp. We did […]
DIY Soil Testing with Arduino and FC-28 Moisture Sensor
In this article, we are going to interface an FC-28 Soil moisture sensor with an Arduino. This sensor measures the volumetric content of water in soil and gives us the moisture level. The sensor gives us both analog and digital output, so it can be used in both analog and digital mode. We are going to […]
LazyMax 1000: Arduino Phototransistor and Haptics Project
The idea for this Arduino phototransistor project came to me based on an idea that was shared by one of my friends at the FabLab. He talked about how his lab only has stools for people to sit on. Being very uncomfortable, the person succumbs to the discomfort and stands up to move around. In […]
Arduino and Processing IDE Communication Tutorial
In this tutorial, we will make the communication between the Arduino and Processing. We will make the communication in both the ways, from the Arduino to Processing and from Processing to the Arduino. We will change the color of the serial window in the Processing IDE through the potentiometer value sent from the Arduino IDE. […]
How to Make an Arduino Temperature Data Logger
In this project, we are going to make an Arduino Temperature logger that will get the temperature value from the LM35 temperature sensor and the time from the DS3231 Real Time Clock module. Then we will store these values in the SD card file using the mini SD card Module. After that, we will access […]
Revive Old Drive-In Speakers with a Modern LED Twist
When I was a kid we went to the drive-in theater to see movies like The Legend of Boggy Creek and Evel Knievel. I loved those movies but I remember just as vividly those retro-cool metal speakers that entered into our car for these campy films. A few years ago I found one of these […]
