REGNRSG 105 Lecture Notes - Lecture 9: Carriage Return, Voltage Divider, Bit
Document Summary
1 32x32 pixel gif icon: observe the schematic of an led connected to an arduino (ground -> led -> resistor -> 5v). The led will be off: observe the schematic of led to breadboard (d3 -> led -> resistor -> d2). Digitalwrite(3, high): an led connected to the 5v and gnd of your arduino board without series resistor will break. An led connected to an arduino pin without series resistor will burn very brightly, but will not break. The maximum current an arduino pin can supply is 20 ma. In processing we use void setup() and void draw(). The led in the following program should blink with 50hz. Fill in the correct value on the gap on line 7: Consider a situation where one start bit an done stop bit are transmitted per byte. Unsigned long: let"s say we have a signed byte.
