### Power supply
For power supply a 5V source is needed. Most easily this can be done via a USB power supply. The power supply should support minimum 500mA. For buffering current peaks some users reported to use a large electrolytic capacitor like a 2200uF between ground and VCC.

**:bangbang: Attention**: the focus of the OV2640 needs to be adjusted, as it is normally set from ~40cm to infinity. In order to get an image that is big enough, it needs to be changed to about 10cm. Therefore the sealing glue on the objective ring needs to be removed with a scalpel or sharp knife. Afterwards the objective can be rotated clockwise until the image is sharp again.
