Circuit Documentation
Summary
The circuit in question is designed to control an RGB LED using three pushbuttons. Each button corresponds to one color channel of the LED (Red, Green, and Blue). The circuit is powered by a 9V battery, which is regulated down to a lower voltage suitable for the RGB LED and the pushbuttons. A resistor is used in series with the LED to limit the current through it.
Component List
9V Battery
- Description: A standard 9V battery providing the power source for the circuit.
RGB LED (Wokwi compatible)
- Description: A four-pin RGB LED with one common pin and three separate pins for the red, green, and blue channels.
Resistor
- Description: A resistor with a resistance value of 200 Ohms, used to limit the current through the RGB LED.
Pushbutton (x3)
- Description: Three pushbuttons used to control the individual color channels of the RGB LED.
Voltage Regulator
- Description: A voltage regulator used to step down the voltage from the 9V battery to a lower voltage suitable for the RGB LED and pushbuttons.
