In this design, only one push button switch is used to control the light output (from a bunch of ... dim, medium, and high brightness * Test Configuration: MCU: Arduino UNO R3 IDE: Arduino 0022 ...

Using an IRFZ44N, I made a simple LED driver and used an Arduino Uno directly. Remember the Arduino pins go up to 5V and I used the fade example that generates PWM out of the box.

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 – ...

At its heart is an Arduino UNO, which syncs the RGB LED ‘bubbles’ and a servo-driven aiming arm to the game’s real-time data. A Lua script monitors MAME’s memory locations to match the ...

The Arduino Uno board detects the tattoo artist’s gestures via a distance sensor, and signals the machine with an on or off output. Watch this video on YouTube . Source: AH : WTech ...
