Here is a simple do it yourself project of a little melody maker useful for all those hobbyists interested in making electronic toys or fancy gizmos for their kids. 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]
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.
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]
