Learning board - 1
Introduction
The first board in this series of learning boards consists of a few input and output devices. To get you started learning the Raspberry Pi Pico. From this board, we will do 7 Simple Lessons. You can easily change the task to fit your students need or create more lessons. The Gerber file to learning board 1 is available to download here:
Electronic Components Review:
LED
Description: A semiconductor light source that emits light when an electric current flows through it. LEDs are commonly used as indicators in electronic circuits. How it works: It emits light when electrons recombine with electron holes in the device, releasing energy in the form of photons. Usage: Indicators, display elements, illumination.
Resistor
Description: A passive two-terminal electronic component that resists the flow of electric current. How it works: It limits the current flowing through a circuit and is characterized by its resistance value. Usage: Current limiting, voltage division, setting bias points.
Push Button
Description: A switch that is activated by pushing it. How it works: Completes or interrupts an electric circuit when pressed. Usage: User input, toggling, control switches.
HC-SR04 Ultrasonic Sensor
Description: An ultrasonic ranging module that measures distance using ultrasonic waves. How it works: Sends ultrasonic pulses and measures the time taken for the echo to return to calculate distance. Usage: Distance measurement, object detection.
Passive Buzzer
Description: An audio signaling device that does not generate a tone on its own. How it works: It requires an external waveform to produce sound. Usage: Alarms, notifications, simple sound generation.
SSD1306 0.96 inch
Description: A small OLED (Organic Light Emitting Diode) display. How it works: Each pixel is a small organic LED, and the display emits light when an electric current is applied. Usage: Display information, graphics, user interface.
