Vnc connect iot5/19/2023 ![]() ![]() Although it isn’t absolutely essential, it’s useful to monitor the plant’s growth and keep an eye on the outlet pipe to make sure everything is working.Īctivating the Pi’s VNC Server is rather simple, as shown on this page:įollowing which, you can download the VNC Viewer application on any other device (for a smartphone, tablet or PC):īoth softwares are part of the VNC Connect package which is free for non-commercial usage, and cross-platform compatible. VNCĪ VNC Server running on the Pi, allows it to be controlled from any computer with the appropriate access credentials, on the same VNC Connect (by RealVNC) account. The software in question, is called VNC Connect and it’s server-side application comes pre-installed in practically all new versions of NOOBS and Raspbian. This system was programmed in Python, on a Raspberry Pi Model 2 B over a VNC (Virtual Network Computer) cloud connection. When the relay is switched on the valve opens, releasing water into the outlet pipes. This is sufficient to turn on the relay which in turn, controls the mains power supply to the solenoid valve outside. The motor driver bumps up the voltage from signal level to 12 volts. Although these timings are far from perfect, they can and will be adjusted as the experiment progresses, depending on the plant’s observable requirements.Įxternally, this signal triggers board-pin 12 of the GPIOs, which is in turn connected to an L298N motor driver. The irrigation system is triggered at certain fixed local times, namely, 06:00, 14:00, 14:30 and 18:00. Since there happened to be an unconnected solenoid valve connected to the pipeline anyway, it was the perfect opportunity to throw in a little home automation to fix this. By evening they had keeled over and looked terribly dehydrated… to say the least. One morning I didn’t remember to water the peace lilies outside my window. ![]()
