Hi I would like to experiment with some sensors and actuators with the [microbit](https://core-electronics.com.au/micro-bit-australia.html). Can you please recommend which parts would be suitable for : servo piezo buzzer moisture, humidity, temp sensor speaker Thanks Damian Clair ---

Hi Damian, Welcome! @Stephen has been spending a lot of time with micro:bit hardware lately, he’ll have some great suggestions. ---

Hi Stephen That’s an awesome list and I shall place an order tomorrow. With regards to the servo I notice dit was rated at 6v and the micro it only outputs at 3v. Would this impact upon its performance ? Regards Damian Clair ---

Hi Damian, The servo should still work off 3.3v, it will just turn a bit slower. It is not ideal to power it directly off the Microbit, but it works in a pinch!
