You can control the brightness of these LEDs using variable resistors VR1, VR2 and VR3 respectively. Parts Needed. Arduino UNO board – 1 ; 5mm LEDs Red, Green, Blue – each 1 ; 100K Variable resistor – ...

The 1K resistors are used for base current limiting, and the 390R resistors limits the operating current of the LED display segments. In the Arduino board, digital outputs from D2 to D8 are used to ...

From resistors and LED modules to light sensors, each block represents a real component that can be attached to each other via magnetic connectors, hopefully creating a circuit in the process.

And there are current limiting resistors to protect the Raspberry Pi’s inputs. ... Arduino pin 13 LED, Pi GPIO pin 13 LED, headers for full Arduino pin access, and ICSP header for AVR microcontrollers ...

It may look a little shoddy, but what’s amazing is that this very functional 3-D interface was built by a hobbyist with parts most DIYers can find in their couch cushions—six resistors ...
