Raspberry pi commands For the initial use, connect the pi to the monitor using HDMI cable. You can configure WiFi/LAN connections so that, you can login remotely into it later. Default credentials to log into Pi are Username: pi Password: raspberry To find the available networks, you can use the following command which will give you a list of SSID's (network names) sudo iwlist wlan0 scan sudo nano /etc/wpa_supplicant/wpa_supplicant.conf network={ ssid="testing" psk="testingPassword" } Once the wifi is configured, you can login remotely from other devices. While in the same network, you can use the following command ssh username@pi-ipaddress ssh pi@192.168.x.x Alternatively, instead of finding out Pi ipaddress everytime you connect, you can add the following details to your.. Host pycam user pi Hostname pycam.local port 22 ServerAliveInterval 5 ServerAliveCountMax 10 sd

That was neat, as he do not have do a thing other than standing on the weighing scale. I have got some inspiration from him but, I do not have any knowledge in electronics.  1 Temperature and humidity sensor using NodeMCU init.lua function...
