Solar Tracker

A clear blue sky dominates the image, with the upper segment of a solar panel array visible in the lower part. The structure is supported by sleek metal beams, suggesting a modern, sustainable energy theme.

Energy Monitor

Build a compact solar tracker that follows sunlight, improves panel efficiency, and introduces real-world control systems through accessible hardware.

A collection of electronic components including an Arduino board, breadboards, batteries, potentiometers, and various sensors arranged neatly on a flat surface.

Smart Robot

Design an Arduino-based energy monitor that measures voltage, current, and power consumption while turning raw readings into useful insights.

A homemade robot constructed from household materials and electronic components including a microcontroller board and several colorful wires protruding from its top. The body appears to be made from stacked containers wrapped in black tape, with a pair of ultrasonic sensors resembling eyes.

Air Station

Create a smart obstacle-avoiding robot combining ultrasonic sensors, motor control, embedded programming, and practical autonomous navigation.

A small electronic project is assembled on a breadboard placed on a wooden surface. It includes wires, a microcontroller, and a display screen showing a humidity reading of 39% and a temperature of 25C. Various tools like wire cutters and digital components such as a seven-segment display are laid around it. A potted plant is visible in the top left corner.

Build With Zexpy
