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
In the program, the timer I used the was: Count = 200
What is the Configuration?
Based on the given information, the configuration for generating a Knight Rider Pattern on the 8 LEDs on the Explorer 16 development board can be determined as follows:
1. Voltage: The power supply voltage is +3.3V.
2. Resistance: A 10k resistor is used in the circuit to limit the current flow through the LEDs. However, it should be noted that the resistance value of 10k is not directly related to generating the Knight Rider Pattern but rather for current limiting purposes.
3. Current: The current flowing through the LEDs is given as 0.00033A (330 microamps). This current value is important for determining the LED's forward voltage drop and ensuring it is not exceeded to prevent possible damage.
4. Timer: The program uses a timer with a count value of 200. However, without further context, it is difficult to determine the specific relationship between the timer count and the pattern generation.
Overall, the given information provides the basic electrical parameters (voltage, current, resistance) and the timer count used in the program. However, additional details would be required to fully comprehend the specific configuration and how it generates the Knight Rider Pattern on the 8 LEDs.
To generate a Knight Rider pattern on the 8 LEDs of the Explorer 16 development board, you would need the following configuration:
1. Voltage: +3.3V: This is the voltage supplied to the LEDs. Ensure that your power supply is set to provide a constant +3.3V.
2. Resistance: 10k: Each LED should be connected in series with a current-limiting resistor to prevent excessive current flow. Assuming a forward voltage drop of around 2V for each LED, you can calculate the resistance using Ohm's Law: R = (V_supply - V_LED) / I_LED. In this case, R = (3.3V - 2V) / 0.00033A = 3.03kΩ.
3. Current: 0.00033A: To determine the appropriate current value, make sure to choose resistors that limit the LED current within their specified maximum forward current ratings. It is typically recommended to keep the LED current between 5-20mA.
4. Timer: Count = 200: In your program, you're using a timer with a count of 200. This count value determines the time interval between each step in the Knight Rider pattern. You may need to adjust this value based on your desired speed of the pattern.
Overall, connect each LED in series with a 3.03kΩ resistor to a +3.3V power supply. Control the LEDs using a timer with a count of 200 to achieve the Knight Rider pattern.
To generate a Knight Rider pattern on the 8 LEDs of the Explorer 16 development board using the given specifications, you will need to configure the LEDs in a specific way. Here's how you can do it:
1. Connect each LED to a separate I/O pin of the microcontroller on the Explorer 16 board. The microcontroller will control the LEDs to turn them on and off.
2. Make sure to connect the anode (longer leg) of each LED to the I/O pin and the cathode (shorter leg) of each LED to a current-limiting resistor.
3. Use resistors with a value of 10k ohms (10,000 ohms) to limit the current flowing through the LEDs. This will prevent excessive current from damaging both the LEDs and the microcontroller.
4. Apply a voltage of +3.3V to the circuit. This voltage will power both the microcontroller and the LEDs.
5. Use a timer in your program to control the timing of the Knight Rider pattern. Set the timer count to 200. This means that the pattern will change every 200 timer counts.
6. Configure the microcontroller's I/O pins as outputs and write the appropriate logic levels to the pins to turn the LEDs on and off in the desired sequence. For example, you can start with all LEDs off, then turn on one LED at a time, moving from left to right, and then repeat the sequence in the opposite direction.
By following these steps, you should be able to configure the 8 LEDs on the Explorer 16 development board to generate a Knight Rider pattern using the specified voltage, resistance, current, and timer count.
