Educational experiments

The Pico Technology library of science projects contains a number of educational experiments suitable for use with our oscilloscope and data logging products.

If you are involved in the teaching of science we would love to hear from you. We are looking for people willing to perform and write up new experiments for this collection. For more details on this, please read our guidelines on submitting science projects.
