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 […]

Greetings, welcome back. Today, we will demonstrate the process of creating a water level detector utilizing an Arduino Uno and water sensors. There are numerous water level sensor tutorials available online, but this method stands out. To begin with, let’s talk about the components required for creating a water level indicator and controller. Component required […]

This Color Detector utilizes an Arduino Uno R3 and TCS3200 color sensor module. Color identification and detection can be beneficial for food-processing units, color printer applications, paint-mixing applications, and other industrial applications such as robotics. This project is designed to identify basic colors (red, green, and blue) that are present in LEDs in a single […]

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 […]

How to validate a Proteus LED or bar-graph simulation: supported models, firmware co-simulation, active indicators, and why simulation is not a prototype test.

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 […]
