Need to autonomously monitor for that specific color value? Want to hone in on that magenta ball? Or follow that aquamarine line? The BH1749NUC-based Qwiic RGB Sensor is here for all of your red<\/span>, green<\/span>, blue<\/span>, and infrared<\/span> color-sensing needs.<\/p>\n\n The BH1749NUC<\/strong> features an I2<\/sup>C interface and a programmable interrupt output. It senses red, green, blue, and infrared in its field-of-view, then reports each channel as a 16-bit value. Additionally, it features programmable IR and RGB gains and a variable measurement rate.<\/p>\n\n Also included on the breakout are individually-controllable white, red, green, and blue LEDs. The LEDs are managed with a PCA9536<\/strong> 4-channel I\/O expander. The paired LEDs and I\/O expander allow you to customize illumination on your objects of interest with a simple I2<\/sup>C interface -- no extra GPIO-control required!<\/p>\n\n Check out the documents section for a pair of Arduino libraries -- for both the BH1749NUC<\/a> and PCA9536<\/a> IC's -- and a handful of examples to help get you started.<\/p>\n\n The Qwiic RGB Sensor uses our simple Qwiic<\/a> interface, so it requires no voltage translation and no figuring out which pin is SDA or SCL; just plug it in and go! As with any Qwiic board, this product includes a pair of Qwiic connectors to support a chain of multiple sensors.<\/p>\n\n NOTE:<\/strong> The I2<\/sup>C address of the BH1749NUC is 0x41 \/ 0x39 and is jumper selectable to 0x38. A multiplexer\/Mux is required to communicate to multiple BH1749NUC sensors on a single bus. If you need to use more than one BH1749NUC sensor consider using the Qwiic Mux Breakout<\/a>.<\/p>\n\n We do not plan to regularly produce SparkX products so get them while they\u2019re hot!<\/p>\n\n Features:<\/strong><\/p>\n\n Documents:<\/strong><\/p>\n\n
