Interfacing 3D Printer Ramps 20X04 LCD Smart Controller with Arduino Using this display, you don’t need a computer to control your 3D printer anymore. In this shield, an SD card is used to transfer the 3D designs to the 3D printer and store the G-Codes. This shield consist of a 20x04 Character Line LCD. Using the rotary encoder on the board, you can move in the device menu and access data. This display is compatible with ramps 1.4 controllers and can be run with marlin and repiter firmwares. ...

GY-31 TCS3200 Color Sensor Features The TCS3200 color sensor uses 64 photodiodes to detect color. The output of this sensor is a square wave. Color intensity is obtained directly from the frequency of the square wave. These 64 photodiodes consist of 16 diodes with red filter, 16 diodes with green filter, 16 diodes with blue filter and 16 transparent photodiodes without filter. All 16 diodes of each type are connected in parallel. To detect any color, the photodiodes corresponding to that color are activ...
