Step 4Mount the battery holder
iImage Information

It's time to mount the battery holder. There are 3 ways of mounting the battery holder. You can choose not to mount it at all and just let it dangle around, you can mount it beside the shield using a popsicle stick (this will of course make it wider) or you can mount it underneath the shield (this will of course make it taller). I chose the last method. You can mount it either with screws or hot glue. When you've mounted it, solder the red and the black wire in the right places (see the schematic in step 3).
