Learn how current, the flow of electrons, powers circuits; measure amps with a multimeter, relate volts, amps, and watts, and compare dc and ac usage.

Discover how analog and digital signals power microcontroller projects with the Swift i/o board, sensors, and ADC conversion, including resolution and LCD displays.

Explore breadboards as reusable, solderless platforms for building circuits with power rails, rows and columns, and power them from the usb port on the computer or benchtop supplies.

Explore how transistors function as amplifiers and switches, covering NPN/PNP BJTs and MOSFETs, gate voltage control, nanoscale sizing, and their role in modern computing.

Blink an led to reproduce morse code and transmit SOS with Swift IO micro. Learn to implement short and long flashes using arrays, for in loops, and if else statements.

Learn to control an LED with two dedicated buttons—on and off—using three state variables, nested if statements, and a ten millisecond debounce to set the LED high or low.

Demonstrates a two-button dimmer that adjusts an led’s brightness via pwm using rising-edge interrupts. Learn to clamp duty cycles with max/min and update the led in a simple main loop.

Read the potentiometer's analog value and map it to a pwm frequency from 50 hz to 1050 hz to control the buzzer pitch, using a 50% duty cycle.

Read the potentiometer's analog input as a percentage, then set the PWM duty cycle to control the LED brightness, demonstrating analog-to-digital conversion and PWM concepts.

Design and implement an RTC-based alarm clock that triggers a buzzer and led at the set time, with a stop button and automatic stop via a duration.

Use the accelerometer to motion-activate a dice roll, detecting shake or tilt with thresholds, and print a random 1–6 after the device steadies, with an LED indicator.
