This Arduino sketch sequentially turns on and off LED strips that are attached under the bullnose of each step in a stairwell. The project uses synchronous serial communication with 74HC595 shift ...
Certain types of discrete transistors, the NPN 2N2222 and the PNP 2N2907, can be operated as inverted mode switches where “inverted” means that the collector is made to serve as an emitter and the ...
The 2N2222 and BC549 transistors are two old components that are still universally used in the vast majority of electrical circuits today. Their applications include amplifiers, filters, impedance ...
We need 64 common cathode RGB LEDs for our cube. Test all LEDs before soldering. Bend all the leads out 90 degrees apart as shown in Fig. 2. Now construct a jig as shown in Fig. 1. Insert LEDs into ...
[Eric Wasatonic] had a box of SWB2433 transistors that he had very little information about. In order to discover their properties, he fired up his curve tracer to compare these transistors with more ...
