Using an Arduino Nano, an analog pH probe, and a crisp OLED display, they’ll build a handheld meter that not only measures soil acidity but also suggests the best plants for that soil. It’s a hands‑on bridge between coding, electronics, and the garden, perfect for the budding scientist who wants tomatoes to taste better or roses to bloom brighter.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eA portable soil pH meter that reads acidity on an OLED screen and matches the value to a plant recommendation. After testing the three included soil samples, your child can take the device to any garden pot, flower bed, or school vegetable patch and instantly know if the soil is ideal for marigolds, blueberries, or even orchids.
