Project library
Each build lists what you'll learn, the parts you need and a realistic cost — filter by what interests you most.
Automation
Build a mini street crossing that cycles red, amber and green on a timed loop — the classic first taste of automation logic.
You'll learn: Timing circuits, sequential logic and breadboarding basics.
Sensors
Read room temperature and trigger a buzzer plus LED warning when it crosses a threshold you choose.
You'll learn: Analog sensor reading, comparison logic and threshold tuning.
Automation
Spin a DC motor and dial its speed up and down with a potentiometer using pulse width modulation.
You'll learn: PWM signals, transistor switching and motor driver wiring.
Home Electronics
A soil probe that blinks when your plant is thirsty — the friendliest possible introduction to sensors.
You'll learn: Analog input scaling, calibration and conditional logic.
Robotics
A two-wheeled rover that reads distance and steers itself away from walls, boxes and shoes.
You'll learn: Ultrasonic ranging, motor control and simple autonomy loops.
Home Electronics
Scroll your own messages across an 8x8 matrix and learn how a single chip drives dozens of LEDs.
You'll learn: SPI communication, multiplexing and display buffers.
Home Electronics
A lamp that fades on when the room darkens and remembers your preferred brightness curve.
You'll learn: Light sensing, PWM dimming and relay-free load control.
Robotics
A small buggy that tracks a black tape line using reflectance sensors and gentle steering corrections.
You'll learn: IR reflectance sensing, differential drive and tuning loops.
Sensors
Shake it and a seven-segment display rolls a number — a tiny project with a satisfying payoff.
You'll learn: Random values, tilt switches and seven-segment driving.
Sensors
Detect movement in a doorway and sound a staged alert with an arming delay you control.
You'll learn: PIR sensors, state machines and debounce handling.
Automation
A fan that ramps its own speed against a temperature curve and reports what it is doing over serial.
You'll learn: Closed-loop control, PWM fan curves and serial logging.
Robotics
A two-joint servo arm that mirrors the tilt of your hand using an accelerometer.
You'll learn: I2C sensors, servo mapping and smoothing filters.
