A reasonably modern laptop, desktop, tablet or phone works. A laptop or desktop is best for the shared board and coding.
Use a current version of Chrome, Edge, Firefox or Safari. Keep it updated for the best and safest experience.
A working camera and microphone are needed for live classes. Headphones help reduce echo.
Allow the browser to use your camera and microphone when asked; you can still join and use the board if you prefer not to.
