I am working on a school project where I need it to do something on shake. However, it will activate with the slightest movement. Is there a way to change the shake sensitivity? ---

Hi @Whatsuphi — welcome to the forum! I don’t think there’s an easy way to update the sensitivity. Here’s a kind of complicated way that would require some variables. The basic logic used for shake detection (for microbit v2) can be found [here](https://github.com/lancaster-university/codal-core/blob/df05db9e15499bd8906618192a4d482e3836c62f/source/driver-models/Accelerometer.cpp#L121). You could create your own logic that uses the same basic approach, but uses higher thresholds. I think there are a few different concepts being used: 1. Detecting the back-and-forth between high accelerations (zero crossing or threshold crossing) in each direction. 2. Counting the number of zero crossings to see if they are enough to consider it a valid “shake”. 3. Checking if enough time has passed to either: start detecting another shake (if there was one in the past) or to start “forgetting” peaks if it’s been too long since the last one.
