I will have the breadboard mounted in a plastic project case and it will be mounted vertically
i waas wondering if i can use hot glue.
I do not have a soldering iron and don't know how to use one
But if you want reliable connections, get an iron and read up online, it's really not that hard. You'll be glad you did.
I have a friend who built his first embedded PIC project on Solderless breadboard. He mounted it upside down under his portable Model Railroad Module. Lets just say it didn't survice long. After fixing it countless times... he finally soldered it to a matching layout proto board like this: http://www.escience.ca/hobby/RENDER/0001/88/3088/12165.htmlEventhough I would always recommend to *not* buy or use a cheap soldering iron when better ones are affordable and long lasting (I still have my first Weller... bought used in 1978) ... even a cheap Walmart $10 pencil soldering is better than not having one at all.
