+  * [[https://learn.adafruit.com/adxl345-digital-accelerometer/overview|Lots of Details at Adafruit]]
+  * We want to connect to this via the i2c bus
+  * There's an ADXL345 Library by Adafruit, but also by others
+===== IR Opto-Switch =====
+  * I bought [[amazon.de>B00EFOTJZE]] these
+  * I think we should be able to simply connect them to two GPIO pins
+    * actually the emitter can probably be just powered permanently
+      * not sure if I need a resistor, the Amazon page contains really shitty translations
+      * I should hook up one of the diodes to my component tester
+      * actually based on the given foward voltage and current, according to an online calculator I need resistor of about 70ohm
+    * gotta figure out how to connect the sensor
