Hi Guys.... I bought a bigger breadboard. Here is the one I bought:
https://www.amazon.ca/gp/product/B00KHE7O7Q/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1
I am wondering what the two busses on the top are used for. Presently, I am using the top horizontal buss to run my + and - to the posts and then to all the breadboard rails. But I am not sure why there is a second horizontal rail directly underneath the first. At first I tried daisy chaining those two busses, but my power supply started showing a short. So, that second rail must be independent of ther first, but I am not sure for what use.
Also, wondering why 4 posts are included. I assume you can use the green one for ground, or for a mid point if you are using two power supplies, but why is there a green and blue one in addition to the red and black?
Thank-you. I was watching some YouTube video and I found the board, but I could not find someone addressing the question above.
