In this guide we will learn how to play with a cheap ‘n’ cheerful temperature and humidity sensor DHT11 – the minuscule 4-pin sensor accurate enough for most do it yourself projects need to read and record humidity and temperature levels. Sensor Overview The DHT11 sensor is a perfect blend of one temperature sensor and… [Read More]
Arduino Projects
Arduino is one of the most exciting embedded development board evolved from the open source community to learn and build arduino projects for hobbyists and electronic enthusiasts. It is the best resource for making DIY projects and Prototypes.
The Arduino makes use of different Microprocessors and on-chip microcontrollers to design devices that interact with the sensors and actuators.
The most popular variants of Arduino are Arduino UNO, Arduino YUN, Arduino LEONARDO, Arduino NANO, Arduino MEGA.
Arduino comes with prebuilt shields for ease of interfacing various add-on modules like GSM/GPRS shield, Ethernet shield, USB shield, and Wireless shield for IOT projects.
Attiny85 Programming Adapter for Arduino
Using an Attiny85 microcontroller is an attractive and economical way to build a minuscule Arduino project backed by a few lines of code. Very often such a project will demand an external adapter to program the Attiny microcontroller with the help of an Arduino board, and using a small ready-to-use module can reduce development time… [Read More]
Ultrasonic Water Level Monitor
Here’s a little idea to monitor the level of water in a water tank with the help of an ultrasonic sensor module. The build process is very simple, and best understood by referring to the hardware setup diagram. The technique behind this idea is easy to understand. The ultrasonic sensor sends out an ultrasonic pulse,… [Read More]

For extreme simplicity and flexibility, the circuit is built around the inexpensive microcontroller board ‘Digispark Attiny85 (Rev2)’. By default, the finished circuit will play the “twinkle… [Read More]
Poor man’s USB Rubber Ducky
I believe most readers are familiar with Hak5’s USB Rubbery Ducky. Well, simply it is a $45 key stroke injection tool, masked as a generic usb flash drive, widely used to hack unlocked computers. Computers recognize it as a regular keyboard and accept pre-programmed keystroke payloads at speeds beyond 1000 words per minute. In this… [Read More]
Nano Digital Volt Meter
Nano Digital Volt Meter is a microcontroller-based simple DIY project for electronics hobbyists and makers. It is a compact digital voltmeter which can incisively measure input dc voltages in 0 to 55V range. The project is built around an Arduino Nano microcontroller board. Another key component is an I2C LCD panel, which is easier to… [Read More]
USB Xmas Candle
Here is a fascinating USB-powered LED Candle armed by the Digispark USB Development Board based on Attiny85 microcontroller. Thanks to Digispark – despite the lilliputian size, it’s packed with capabilities, and apart from having fewer I/O pins it can do most of what the microcontroller in the Arduino can do. Further, you can program it… [Read More]
