Cathode Ray Oscilloscopes – Working and Operational Details
In this post I will elaborately explain how Cathode Ray Oscilloscopes (CRO) work and its internal construction. We will also learn how to use a CRO using the various controls and understand the graphical representations of the various input signals on the display screen of the scope. Importance of Cathode Ray Oscilloscopes (CRO) We know that majority […]
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 […]
