Servo Controlled Time-Lapse Camera

Things used in this project

Hardware components

Raspberry Pi Zero
Raspberry Pi Zero
Get the newer version that has a camera interface. And make sure you got a Micro-USB cable to connect the Pi to your computer
XinaBox IR03
XinaBox OC05 - Servo Driver
XinaBox XC10
XinaBox MD01
Really just a spacer to mount the servo on, so very optional.
Camera Module
Raspberry Pi Camera Module
Remember to get the narrower flat cable that fits the RasPi Zero
3.7v LiPo battery (generic)
Servo (generic)
Any small servo with standard 2.54 mm 3 pin header cable, and mounting gear (nuts/bolts, rubber bands, cable ties, glue, or what ever is your preference)

Software apps and online services

Raspberry Pi Raspbian Lite Etcher
XinaBox OC05 Servo Driver
