Use a VNC Viewer to connect to your Raspberry Pi from a laptop.
You want to measure soil moisture or automatically turn on the porch light when it gets dark using your Pi. Will you need to have your HDMI monitor, keyboard, and mouse connected at all times to your Pi to be able to control it? No! Connect to your Pi remotely using your laptop.
Follow these steps to set up your remote connection. Note that you do need your monitor, keyboard, and a mouse for the initial set up.
