# Assignment: Blink a led ## Goal Check that your local environment is working properly. ## Step 1 Create this schematic: ![](schematic/assignment-1_schem.pdf) ![](schematic/assignment-1_bb.pdf) The colors on the wires used does not matter. The resistors orientation is not important, but the LED's orientation is important. ## Step 2 Implement `setup()` and `loop()`. In `setup()` configure the LED pin and blink the LED in `loop()`. Use these functions: ~~~ .c++ Serial.begin(115200); Serial.println(string); pinMode(pin, mode); digitalWrite(pin, state); // HIGH or LOW delay(); ~~~ ## Tips * It is useful to print a startup message just to see when the application has started.
