If you are diving into the world of Arduino robotics or environmental sensing, you have likely encountered a frustrating problem: managing wires . Connecting a single LED or a button is easy. Connecting 10 sensors—a ultrasonic distance sensor, a servo motor, a temperature sensor, and an LCD display—results in a nest of jumper wires that looks like a bowl of tangled spaghetti. This expansion board (or "shield") is designed to
void loop() // Sweep from 0 to 180 degrees for (pos = 0; pos <= 180; pos++) myservo.write(pos); delay(15); int distance = readUltrasonic(); Serial.print("Angle: "); Serial.print(pos); Serial.print(" cm: "); Serial.println(distance);
The reset button on the shield should align perfectly with the reset button on the Arduino. The USB port on the Arduino should stick out the "short side" of the shield.
Enter the . This expansion board (or "shield") is designed to solve exactly this problem. It turns your messy breadboard into a clean, plug-and-play hub for sensors and servos.
