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 ...

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 ...

The LED connects across the output transistor because this approach lets the inductive kickback voltage add to the battery-supply voltage and makes the LED brighter. This circuit operates well from ...

4×4×4 Led Cube Circuit Diagram The circuit diagram for a 4 * 4 * 4 LED cube using Arduino Nano involves several components and connections to ensure proper functioning. Here's a step-by-step ...

Even though there are other ways to blink a LED and other ways to make an oscillator, [Eric]’s circuit is about as simple as it gets. [Thanks, fede.tft] ...

Another way to handle both positive and negative LED polarity is to use two transistors and a switch. A transistor is a component that can act as a switch or an amplifier, depending on the voltage ...
