Music reactive 12v RGB led strip is a fun project which changes its color based on the sound of the music. This project is built using an Arduino Uno board that controls multiple color effects of LED ...

arduino and tinkecad on LED and pnp transistor connect the (+) to pin (13) and connect the ground to (-) then start with capacitor (0.33mF) on (E) port and connect the out to the secend capacitor (0.1 ...

LED matrix. The LED matrix consists of 35 LEDs connected as per the circuit diagram. Seven transistors are used in the circuit to enhance switching action of the MCU. Collector terminal of each ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

“The LED may also flash when the E and C leads are switched, but the flash rate will be faster,” Gerbig explained. “This reflects the fact that some types of transistor will operate with their emitter ...
