Hi Safoura,
I would spend it on affordable microcontroller boards that are well-supported by educational software for physical computing (
MicroBlocks support being my undeniable first choice as an open source physical computing software tool, because it's live, like Scratch, and founded by the developer who led Scratch development at the outset.)
I am particularly fond of hardware with wireless radio support (Wi-Fi and/or BLE) so that learners can easily bridge their creations into the world of "Internet of Things" (IoT). Example of boards I like:
* micro:bit, Adafruit Circuit Playground Express Bluefruit, Adafruit Clue, or any other Nordic Semiconductor boards (with nRF52 MCUs)
* Espressif ESP32 hardware (and kits if the board doesn't have many sensors/actuators on it already)
* Raspberry Pi Pico (RP2040) wireless version boards and kits
I would like to see students pick up microcontrollers, sensors, and actuator components to instrument and actuate the real world. Every student should have these tools in their backpack, just like they carry around calculators.
Let me know if I can help further. Good luck!
