Créez votre Testeur de Composants (Arduino Nano) : Conception de A à Z sur Proteus !

Welcome to this second part dedicated to finalizing our smart transistor tester based on the Arduino Nano. After designing the schematic in the first video, we now move on to the crucial validation and simulation phase. Discover how the microcontroller analyzes connected components in real time to automatically identify: The transistor type (*NPN or PNP*). The exact pinout (*Emitter, Collector, Base*). The component's health status (Good or faulty). Together, we test several popular models such as the TIP41/42*, the *2N3055/MJ2955 power transistors, and the BD139/140 series. This project is an ideal solution for saving time and avoiding multimeter reading errors. Key points of this video: Correction of the LCD wiring errors from Part 1. Demonstration of automatic NPN/PNP identification. * Pin swap test to verify code reliability. Presentation of the source code and tips for translating it into French.
