Pulse-width modulation (PWM) or duty-cycle variation methods are commonly used in speed control of DC motors. The duty cycle is defined as the percentage of digital ‘high’ to digital ‘low’ plus digital ‘high’ pulse-width during a PWM period. Fig....
Thanks to the invention of camera gimbals/stabilizers, we are now able to capture videos smoothly and easily. You will find plenty of different types of camera gimbals in the market, some with multiple built-in features, but what we are...
Using the Internet of Things (IoT) in homes and industries it is possible to control any electrical or electronic equipment. Moreover, you can get the information from any sensor and analyse it graphically or in any user-defined format from...
This RFID Based Access Control System is built around Arduino UNO board, RFID reader module, solenoid lock and a few other components.
RFID is a non-contact, automatic identification technology that uses radio signals to identify, track, sort and detect a...
Pulse-width modulation (PWM) is one of the oldest and widely used techniques of controlling electrical motors. To control the speed of the motor, the average value of the PWM pulse is controlled by a switch. If the switch is...
Thanks to the various wearable health devices available in the market today, we can easily monitor our health status at home, without visiting the doctor. How about making one yourself?
In this DIY project, we will try to make a...
Generally, solar panels are stationary and do not follow the movement of the sun. Here is a solar tracker system that tracks the sun’s movement across the sky and tries to maintain the solar panel perpendicular to the sun’s...
The circuit for an LPG leakage detector is readily available in the market, but it is extremely expensive and usually based on a microcontroller (MCU). Presented here is a low-cost circuit for an LPG detector that you can build...
If you’re still using traditional keyed locks, then you must be always worrying about losing the key or somebody breaking into your house. With traditional locks, there is higher risk of keys being misplaced or getting into the wrong...
Today, home automation using Internet of things (IoT) is one of the major domains which is attracting attention from large tech companies.
We all want to own a smart home, but sometimes language becomes a barrier in setting up IOT...
