How to use W335 Models Electronic Circuit ?

The W335 was an amazing experience to play with as it had many fun activities and I could experiment with each of the pieces. The W335 is a circuit-making set in which there are plastic/metal pieces that can be clipped together to create different types of circuits. There are many circuits illustrated and explained in the booklet, but it was more fun to experiment with the pieces to try and make more circuits. Below are three different circuits that I made from the booklet. They are labelled 1-5 in difficulty, with 1 being easy and 5 being hard.

To start off, I made a simple circuit with the battery pack, two straight connectors 3 pins long and an LED light. This one was rated a 1 in difficulty, and even younger kids will be able to attempt this without instructions as the colourful diagram made it really easy to find the parts. The two 3 pin connectors were parallel to each other and each was connected to a terminal on the battery pack. They were then connected to an LED light to create a closed circuit. To experiment and test my own knowledge, I replaced one of the 3 pin connectors with a press switch. On the press switch, there was a metal plate which was connected to one end but not the other. When the plate was pressed, it connected both ends to create a closed circuit.

Now, the next circuit was slightly harder, with a difficulty rating of 4. This circuit allowed me to make a working FM radio using the radio module provided. For this circuit, connectors of various lengths, the speaker, radio module and battery pack were used. It was really fun to listen to, even though it was challenging to connect all the parts in the right order!

Finally, the last model I made was an ambulance siren, rated at difficulty 5. It used many of the pieces in the kit and was a real test of my understanding of circuits. I was so proud of it when I finished that I took a photo of it, which you can see below. It was interesting to observe the change in sound and volume when I swapped out pieces and changed their order. While it took me a while to finish, it was perfect for annoying my parents.

So, the W335 electronics kit was a fun experience for me and would be for anyone who enjoys circuits, using their hands or simply experimenting. Even if you haven’t looked at circuits before, the colourful diagrams and worded instructions make it easy to understand. Overall, you’re sure to have hours of fun with the 335 different models in the kit, just like I did!
