Casper, an extraterrestrial friend of a ghost. Here's the details for his custom print: A print in white transparent filament for displaying a custom name or message that shines brightly with LED lights when plugged into a 5V microcontroller and USB. The micro controller can be programmed to say your text. **Your custom version of CASPER, here is the code you will need** // include library SPI #include <SPI.h> // connect vcc and gnd int LEDPin = A0; //analog output char text[] = "your_text"; void setup() { pinMode(LEDPin,OUTPUT); } void loop(){ digitalWrite(LEDPin,HIGH); delayMicroseconds(text * 1.25 ); delay(200); } Now just write your own function to display the text of your name in the LED Casper can say hello to anyone at any time by typing a word.
