Complete 115-piece circuit kit

This STEM toy includes two DC motors, two motor holders, five bulbs, three three-vane propellers, three four-vane propellers, a buzzer, five crocodile-clip leads, two rocker switches, one single and one double AA battery holder, plus a bulb holder and instructions. The set is designed for children aged seven and above to build simple electrical circuits and explore basic physics concepts through hands-on assembly.

Check voltage and supervision needs

The manufacturer recommends operating the kit between 1.5 V and 3 V and limiting continuous use at 3 V to no more than three minutes to avoid overheating and short circuits. You will need to supply AA batteries separately, as none are included, and ensure an adult supervises younger children during wiring and motor operation.

Suits classroom projects and home experiments

This kit works well for primary-school STEM lessons, Montessori activities and family science evenings where building series and parallel circuits is the goal. It is not intended for advanced electronics prototyping, soldering practice or projects that require higher voltages, programmable controllers or precision measurement tools.

Questions about this item

What does the 115-piece kit include and do I need to buy batteries separately?

The kit contains instructions, five crocodile clip leads, five bulbs, two motors, two motor holders, two rocker switches, three three-vane propellers, three four-vane propellers, one buzzer, one bulb holder, a single AA battery holder and a dual AA battery holder. Two AA batteries are required but not included.

How do I choose between the 115-piece set and the larger 131-piece or 276-piece versions?

The 115-piece set provides the core components for basic circuit experiments. The 131-piece and 276-piece kits add extra accessories for more advanced projects, so pick the larger counts only if you need additional parts beyond the essentials listed here.

The notice mentions 1.5 V to 3 V — what does that mean for everyday use with AA batteries?

Use one AA cell (1.5 V) for standard operation or two AA cells in series (3 V) for higher speed, but limit 3 V runs to under three minutes to avoid overheating and short circuits.
