Arduino SPWM Generator Circuit – Code Details and Diagram
In this post I have explained how to generate sine wave pulse-width-modulation or SPWM through Arduino, which can be used for making a pure sine wave inverter circuit or similar gadgets. The Arduino code is developed by me, and it is my first Arduino code, …and it looks pretty good 🙂 What is SPWM I […]
FM Wireless Microphone Circuit – Construction Details
A wireless microphone is a portable electronic microphone which allows the user to transmit its voice to an amplifier without any wire connection, hence the name wireless microphone. Making a wireless mic at home can be real fun, here I have explained one such simple project which can be used for recording and paying back […]
Arduino based DC Voltmeter Circuit – Construction Details and Testing
In this post, I will show how to construct a DC voltmeter using Arduino where the readings are displayed in 16×2 LCD. The proposed voltmeter design can read up to 30V with tolerance of +/- 0.5 volt. We are going to see how this setup functions and explore other possibilities we can accomplish […]
