arduino componen tester is a testing tool for read value components, for example Resistor, capacitor. etc. Check the condition and name of the pin from: Transistor. FET, SCR, Diode, LED, TRIAC, DIAC, .

With this tester we able to know the BCE pin of a transistor, or KAG pin for each SCR. Simply put the component that will be tested on the tester probe, turn on then the foot position will display on the LCD screen. To be determined and components are very easy to obtain, and very few parts are installed.
