37-in-1 Arduino Sensors Kit

This kit is a fast way to explore inputs, outputs, and tiny experiments without soldering. Start with one labelled module, see the value change, then turn it into a display, alert, game, or moving project.

Before wiring

The module list is checked against the Keyestudio KS0487 guide and Cytron product page, but the physical box or insert should still be matched before wiring.

Start with one module, one Arduino board, one USB cable, and only the jumper wires needed for that module.

Use serial output first. Add the OLED display or motor only after the input is reading correctly.

Water, flame, relay, voltage, and pulse projects need extra care because the sensor reading can be misused if the limits are ignored.

Pick a direction

What do you want to detect or control?

Choose the kind of signal first, then open a module card for details.

Builds that make the kit feel useful

Each card starts from kit modules and current vending items. Optional request parts are labelled only when they come from wider FIT inventory.
