Active LED Illumination: Wireless Communication
Background
- Talk about Camera
- Talk about LED Experiments
You can use subsections if you like.
Below is an example of a retinotopic map. Or, to be precise, below will be an example of a retinotopic map once the image is uploaded. To add an image, simply put text like this inside double brackets 'MyFile.jpg | My figure caption'. When you save this text and click on the link, the wiki will ask you for the figure.
Design Specifications
- Enable multiple programmable light sources for experiments
- Synchronous wireless trigger that can handle 500fps speeds
