LED: There is a built-in LED driven by digital pin 13. When the pin is high value, the LED is on, when the pin is low, it is off. VIN: The input voltage to the Arduino/Genuino board when it is using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin ...

A Charlieplexed digital clock which controls 90 LEDs with 10 pins of a PIC 16C54 microcontroller.. Charlieplexing (also known as tristate multiplexing, reduced pin-count LED multiplexing, complementary LED drive and crossplexing) is a technique for accessing a large number of LEDs, switches, micro-capacitors or other I/O entities, using relatively few tri-state logic wires from a microcontroller.
Examples of this include enabling and disabling the operation of (or power to) other circuitry, reading the states of on-board switches and configuration shunts, and driving light-emitting diode (LED) status indicators. In the latter case, a GPIO can, in many cases, supply enough output current to directly power an LED without using an ...
HiFive1 is an Arduino-compatible development kit featuring the Freedom E310, the industry's first commercially available RISC-V SoC [8] HiFive Unleashed is a Linux development platform for SiFive ’s Freedom U540 SoC, the world’s first 4+1 64-bit multi-core Linux-capable RISC-V SoC ."
A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, ...
