Description
Experience Level: Entry
'm a London designer looking for a quick hands-on assist on a beginner-level Arduino project. It's a total dissolved solids (TDS) meter—basically dips a probe in water, measures quality in PPM, and shows it live on a 16x2 LCD screen. Super straightforward: wire up a Gravity TDS sensor to Arduino (analog pin A1), connect an I2C LCD (A4/A5), add basic code from GravityTDS library. No soldering needed—just breadboard, jumpers, maybe temp compensation if you're keen.
