Course Description

Wireless voltmeter using arduino course, in this course guides you through designing and building a wireless voltmeter that can measure and transmit voltage readings remotely using Arduino. Perfect for electronics enthusiasts, makers, and students, this course covers the essential steps to create a functional and practical wireless measurement tool. You’ll learn how to use an Arduino board to read voltage levels through an analog input, configure voltage dividers to safely measure a range of voltages, and transmit data wirelessly via modules like Bluetooth or WiFi (e.g., HC-05 or ESP8266). The course also explains how to set up a receiver, such as a mobile app or computer, to display voltage readings in real time. Step-by-step instructions guide you through wiring, coding, calibrating, and testing your voltmeter. Alongside practical skills, you'll gain insights into key concepts like analog-to-digital conversion, wireless communication, and data visualization. By the end of this course, you’ll have a fully operational wireless voltmeter and the knowledge to apply these techniques in other remote monitoring projects, enhancing your Arduino and electronics skill set.
