HC-SR04 Ultrasonic Sensor
sensor.distance.ultrasonic
Measures distance by sending ultrasonic pulses and timing echoes, using a digital trigger and echo pin.
Rotates to a specific angle based on PWM signals, controlled by a single digital pin.
RGB LED (Common Cathode)
led.rgb
Emits red, green, or blue light by applying PWM signals to its three cathode pins (common cathode).
220Ω Resistor (Red)
resistor
Limits current in a circuit; this 220Ω resistor has red-red-brown color bands.
220Ω Resistor (Green)
resistor
Limits current in a circuit; this 220Ω resistor has red-red-brown color bands.
Piezo Buzzer (Passive)
