In this experiment we will use an Arduino to adjust the intensity of the red, green and blue LED elements within our RGB LED. This should allow us to create just about any color we like (except black).To control the levels we’ll be using three potentiometers, these can be any style...
Switch + Color Control (RGB) - used for analog RGB LED's Switch + Color Control (RGBW) - used for analog RGBW LED's Switch (using RCSwitch (i.e. Radio Control Switch) - See 'ST_Anything_RCSwitch' example (Requires RCSwitch library, included in this repo) ...
An RGB Color sensor helps you accurately detect an object’s color in your Arduino projects. There are a lot of applications of color sensors in industrial applications too. Sorting the packages based on color, detecting the freshness of perishable items, detecting and correcting lighting color, a...

i want to make a uart communication for my esp32 and gps but my esp32 module doesn’t have the 16 and 17 pin. can i use the other pin for example using pin 22 as a tx and pin 33 as an rx? Reply Download Our Free eBooks and Resources ...
With this function we set the color of an individual pixel (LED). You will need to pass the pixel number (start counting at zero) and the RGB values. For NeoPixel it will call setPixelColor, and for FastLED it will assign values to the leds array. setAll(red, green, blue); This...
Depending on the inserted coin, the color of the LED animation is different. To have an overview, I have made a chart where you can see all functions. I try to paste it here. I have already made some code, which I can upload another day. The goal is to combine everything, with al...
