ARDUINO UNO CODES

- Set digital pins 8,9,10 as outputs

- Set output voltage of the pins with the following order: First pin 8 should be high.Then after 100ms pin 8 should be low and pin 9 should be high. Then after 100 ms pin 9 should be low and pin 10 should be high. Then after 100ms pin 10 should be low and the whole cycle should start again.

Answer 1

Use pinMode() and digitalWrite() functions to set the digital pins as outputs and control their voltages in a specific order.

Step-by-step explanation:

To set the digital pins 8, 9, and 10 as outputs, you can use the pinMode() function in Arduino Uno code. Here's an example:

pinMode(8, OUTPUT);
pinMode(9, OUTPUT);
pinMode(10, OUTPUT);

To set the output voltage of the pins in the given order (8 high, then 8 low and 9 high, then 9 low and 10 high, then 10 low), you can use the digitalWrite() function in conjunction with the delay() function to create the desired timing. Here's an example:

digitalWrite(8, HIGH);
delay(100);
digitalWrite(8, LOW);
digitalWrite(9, HIGH);
delay(100);
digitalWrite(9, LOW);
digitalWrite(10, HIGH);
delay(100);
digitalWrite(10, LOW);

This code will continuously cycle through the specified sequence of pin voltages.
