DIY wattmeter with an Arduino Measuring power and energy using regular multimeters can be challenging or even unfeasible at times. In order to conduct such a precise and reliable measurement, a specific wattmeter is necessary. Due to their high cost, an alternative option is introduced in the form of a homemade wattmeter using an Arduino […]
People love listening to music while exercising. Music provides the motivation needed for individuals to keep exerting energy and get in shape. So, because people enjoy listening to music while exercising, what if an MP3 player only played an individual’s music while they are active? Using music as an incentive to continue exercising would encourage

Being electronics engineers, we consistently rely on meters and instruments to gauge and study the functionality of a circuit. From basic multimeters to advanced power quality analyzers or DSOs, each device serves specific purposes. Many of these gauges are easily accessible and can be bought depending on the measurements needed and their precision. However, there

Hardware Preparation Stepper Motor Driver Board Arduino Board (UNO) If you bought the Arduino Board from ZTW, we have already installed the g-code library for you. If you have your own Arduino Board, you have the option to download the grbl Arduino library from the internet and upload it onto your board using xloader. Power
Having the ability to feel temperature is exciting… However, being able to detect the temperature of an object without any physical contact is truly amazing. The MLX90614 is a sensor with the capability of achieving that. This person can detect temperatures ranging from -95 to 720ºF (-70 to 382.2°C) with a resolution of 17 bits
The NCRB stated that more than 120,000 fatalities in India were linked to fire mishaps from 2010 to 2014. Despite the many safety measures implemented for fires, they still happen from time to time. In the event of a fire, we must use personnel who are not in a secure location to save people and
His creation is a 26-key drum pad setup that combines MIDI and USB connectivity, featuring a fixed velocity byte for 10 drum switches alongside a 16-key velocity-sensitive circuit. This system utilizes piezo sensors to achieve a complete velocity range from 0 to 127. The drums are already chosen to be sent to the MIDI outputs
Intro: RFID Cat Door Only the pet with the correct RFID tag can unlock this specific cat door/flap. Arduino is responsible for overseeing the process. It features a custom antenna large enough to function as a gate, enabling the animal to easily and consistently activate it. Some methods and techniques are borrowed from my previous
This project involves creating a device with either an ESP32 or ESP8266 that can connect with a server from a distance. The gadget will function as an HTTP client by sending POST requests to a PHP script. The aim of these requests is to transmit sensor data (like temperature or humidity readings) to the PHP
