27-27: Fix typo and casing: “Arduino Uno”Correct the product name for professionalism and searchability.
-- AURDINO UNO +- Arduino Uno
28-36: Standardize library list formatting; fix “LCD display” redundancyUse bullets with code formatting for headers/libraries and apply LanguageTool suggestion (LCD, not “LCD display”). This also improves scanability.

36-36: Behavior/doc mismatch: MPU6050 mentioned, but sample uses only ultrasonicREADME claims “upside-down mug” logic via orientation sensing, but the sample code doesn’t use MPU6050/IMU. Either add orientation logic in the sample or adjust the description to match proximity-based behavior.
Want me to add a concise MPU6050 orientation check to the snippet?
123-123: Fix heading level to follow H1>H2>H3 progression (MD001)“Project Documentation” should be H2 at this point, not H3.
-### Project Documentation +## Project Documentation
143-143: Avoid bare URL; use descriptive link text (MD034)Improves accessibility and readability.

In README.md around lines 46 to 56, the taglines are incorrectly placed under
the "Hardware" section. Move these tagline lines to a new section titled
"Taglines" or "Presentation" and replace the current content under "Hardware"
with a list of the actual physical components used in the project, such as the
ultrasonic sensor and servo motor.

Fence Arduino code and handle no-echo edge case; fixes MD018 and improves robustness
Without code fences, “#include” is parsed as a heading (MD018). Also add a pulseIn timeout and handle the “no echo” case to avoid the servo getting stuck.
-#include <Servo.h>
+```cpp
+#include <Servo.h>
Servo myServo;
// Ultrasonic Sensor Pins
const int trigPin = 9;
const int echoPin = 10;
// Servo positions
int servoHome = 90; // Center position
int servoRotate = 0; // 90° anticlockwise
void setup() {
myServo.attach(3); // Servo signal pin
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
myServo.write(servoHome); // Start at home position
Serial.begin(9600);
}
void loop() {
long duration;
float distance;
// Trigger the ultrasonic pulse
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
// Read echo pulse
- duration = pulseIn(echoPin, HIGH);
+ duration = pulseIn(echoPin, HIGH, 30000UL); // ~30ms timeout (~5m range)
+ if (duration == 0) {
+ // No echo within timeout; keep servo in safe/home position
+ myServo.write(servoHome);
+ delay(100);
+ return;
+ }
// Convert to centimeters
distance = duration * 0.034 / 2;
Serial.print("Distance: ");
Serial.print(distance);
Serial.println(" cm");
if (distance > 0 && distance < 10) {
// Object is closer than 10 cm
myServo.write(servoRotate);
}
else if (distance >= 10) {
// Object is farther than or equal to 10 cm
myServo.write(servoHome);
}
delay(100);

66-66: No space after hash on atx style heading
(MD018, no-missing-space-atx)
🤖 Prompt for AI Agents
In README.md from lines 66 to 118, the Arduino code lacks proper markdown
fencing causing the #include line to be misinterpreted as a heading (MD018), and
it does not handle the case when no echo is received from the ultrasonic sensor,
which can cause the servo to get stuck. Fix this by enclosing the entire code
block within triple backticks and specifying the language as cpp. Additionally,
modify the pulseIn call to include a timeout (e.g., 30000 microseconds) and add
a check for a zero duration return value; if zero, immediately set the servo to
the home position and return early to avoid servo lockup.

Fix malformed image markdown
Current syntax mixes two link styles and won’t render. Use standard inline image format.

In README.md at line 127, the image markdown syntax is malformed by mixing two
link styles. Replace the current syntax with the standard inline image format:
use an exclamation mark followed by alt text in square brackets and the image
URL in parentheses without extra brackets or text.
