Using this half-sized breadboard is super easy. First, for small projects, just place your electronic components on the board as needed. The standard double - strip in the middle is great for connecting components. If you want to use it with an Arduino protoshield, simply pull off the power rails. This will make the breadboard thin enough to stick onto the protoshield. When cutting it in half with a saw, make sure to do it carefully to avoid any damage. You can also connect multiple breadboards together to fit your project's size requirements. For maintenance, keep it clean and dry. Avoid getting it wet as it may damage the board. Store it in a cool, dry place when not in use.
