With batteries, jumpers, and other parts you should plan on spending about $100.00 on this project, not including necessary tools like screwdrivers, a computer, and for setting up the Pi Zero: a keyboard, mouse or touchpad, HDMI monitor, and mini HDMI cable or adapter.
I use n to install and upgrade Node.js on the Raspberry Pi.
