Hello friends! Today we will connect an LM35 temperature sensor to an Arduino Uno and reproduce the measurement in Proteus ISIS. We will start with the sensor's analog output, convert that voltage into temperature, and display Celsius and Fahrenheit readings on a serial terminal. Libraries Libraries used in this tutorial Arduino Library for Proteus: V2.0 (2021, used in this tutorial) · latest version: V4.0 (October 2026) Helping Tools Serial Monitor Advance : a serial terminal window for the UART of your board Serial Monitor Expert : the serial monitor with extra debugging tools LCD Library for Proteus V3.0 : 16x2, 20x4 and I2C LCDs to show your readings The circuit is small, but it teaches several important measurement concepts: ADC resolution, reference voltage, sensor accuracy and the d ...
Hello friends! Today we will examine a cascaded H-bridge inverter in MATLAB and Simulink. We will begin with one bridge, work out its output states, and then see what changes when we connect bridge outputs in series and arrange three phases. The historical project is titled “3 Level Cascaded H Bridge Inverter.” We will retain that title, but distinguish a bridge's three possible output levels from the number of phases and the larger set of levels available from a cascade. Those are different properties of a converter. The original diagrams and scope images remain below so you can follow the model. They illustrate an older simulation environment. This revised explanation does not claim a fresh simulation run or treat a screenshot as proof of an inverter's efficiency or hardware readiness. F ...
Hello friends! Today we will study an 11-level, three-phase capacitor-clamped inverter in MATLAB and Simulink. We will move from the meaning of a voltage level to the phase-leg circuit, switching signals, capacitor voltages and output measurements. The project uses the flying-capacitor approach. Its intermediate voltage levels depend on stored capacitor voltages and the selected switching states. The capacitors do not create energy or automatically turn a low-voltage source into an unlimited high-voltage supply. This tutorial explains the historical simulation and provides a structured way to examine or rebuild it. The retained screenshots show the original model; the numerical examples below illustrate design calculations and are not claimed as newly measured results from that model. Figu ...
