The 8 LEDs on the Explorer 16 development board to generate a Knight Rider Pattern on those LEDs.Calculations (Current/voltage/resistance/Time/Frequency/ etc.,):
Voltage: +3.3V
Resistance: 10k
current: 0.00033A
Part A was make the LEDs move from left to right and right to left just like knight rider.
Part b was to use the SW3 button. When SW3 is pressed down and held, the LED pattern moves from left to right, and when SW3 is released, the pattern moves from right to left.
To generate the Knight Rider pattern on the 8 LEDs, you can use a simple code implementation. Here's an example using the PIC microcontroller:
Part A: LEDs move from left to right and right to left
1. Set up the microcontroller and configure the necessary ports for the LEDs.
2. Define a pattern array to store the LED pattern:
unsigned char pattern[] = {0x01, 0x02, 0x04, 0x08, 0x10, 0x20, 0x40, 0x80};
3. Create a loop that continuously shifts the pattern to the right, then to the left:
while(1) {
// Right to Left
for(int i = sizeof(pattern); i >= 0; i--) {
setLEDs(pattern[i]);
delay(200); // Adjust delay for desired speed
}
// Left to Right
for(int i = 0; i < sizeof(pattern); i++) {
setLEDs(pattern[i]);
delay(200); // Adjust delay for desired speed
}
}
Part B: Using the SW3 button to control the LED pattern direction
1. Connect SW3 button to the microcontroller's input pin and configure it as an input.
2. Define a variable to keep track of the LED pattern direction:
unsigned char direction = 0; // Initially moving from left to right
3. Modify the loop from Part A to check the status of the SW3 button and change the direction accordingly:
while(1) {
// Right to Left
if(direction == 0) {
for(int i = sizeof(pattern); i >= 0; i--) {
setLEDs(pattern[i]);
delay(200); // Adjust delay for desired speed
if(SW3 == 0) { // When SW3 is pressed down
direction = 1; // Change direction to left to right
break; // Exit the loop and start moving from right to left
}
}
}
// Left to Right
else {
for(int i = 0; i < sizeof(pattern); i++) {
setLEDs(pattern[i]);
delay(200); // Adjust delay for desired speed
if(SW3 == 0) { // When SW3 is released
direction = 0; // Change direction to left to right
break; // Exit the loop and start moving from left to right
}
}
}
}
Note: The delay function should be implemented separately according to the microcontroller's specifications and clock frequency.
