Please log in for more thread options OK, I know absolutly nothing about electronics but I'm trying to learn some basic electronics/circuits by myself. So, I got a breadboard, a book with some basic electronic info and projects, some components and a variable power supply that has 3V, 6V, 9V and 12V. My question is how do I connect the power supply to the breadboard. The breadboard I got was one that has 3220 holes and is mounted on to a black backing plate that has 4 connectors labled Va, Vb, Vc and Ground. Do I connect the red and black wires from the power supply to the red and black connectors on the backing plate? Would I use the matching red and black connectors from the breadboard? And where should I put them? Va, Vb? What do I do about the ground? From there how would I power the circuits so that my led will glow like it says it should in the book. I did search the internet for breadboard basics, but couldn't seem to find any info on how the power supply should be hooked up. Any and all advice would be appreciated. Thanks. | |||||||||||||||||||||||||

Most designs have groups of 5 holes on opposites of a groove connected together, so you can plug a .3 inch wide integrated circuit package straddling the groove, with 4 additional holes for each pin to connect other parts. Along side of those sets of paired 5 hole groups are long rails running the opposite direction (parallel to the grooves) to act as supply distribution. Some designs have the long strips divided in half at the center and you have to add a small jumper at the center to have the rails go all the way along the board. Do you have a multimeter, yet? You can get one at Walmart for just a few bucks, and you will soon need it for your experiments. You can wrap a short length of bare wire around the probe tips, and explore what the grouping is on your board, before you try to use it to connect things together. Once you understand what you have to work with, there are no rules. You can plug the supply voltages in anywhere you want. You can use the long rails for supply distribution (if you have lots of things to connect to the supply) or you can use them to carry signals across the board. They are just connections, after all. | |||||||||||||||||||||||||

Dear Frnd, Actually I am not able to imagine the exact board which you are having, can you send me some photograph of the board, But,you may use following tips : 1. Find out Va is being connected to other points in the breadboard? Where it is being connected, vertically or horizontally to the holes. 2. Take care that power supply positive and common does not short through the breadboard, atleast check the connection twice before switching ON Hope this will help you. You can e-mail me on yuvraj_gsm@yaho.co.in Regards YUVRAJ Service & Development Engg INDIA | |||||||||||||||||||||||||

If so, then yes, the black wire goes to the "Ground" post, and the red one can go to any one of the three - that's your call (which is why they only have them labeled a, b, & c - you can call them anything you want to.). Then, I have seen those protoboards where they already have the buses connected to the posts, but mine isn't like that, so I have to actually wire from the posts to the buses where I want power and ground. If yours _does_ have the posts connected to the buses (underneath or whatever), then it should be clearly documented in the instructions. Otherwise, just use the same #24 wire as you use for your breadboarding. A handful of that 25-pair telephone trunk cable is a fabulous source of wire for that sort of thing - you can even color-code your stuff. Or, if you want it to look all cerebral, get some #24 bare tinned bus wire and some #24 teflon tubing... Have Fun! Rich | |||||||||||||||||||||||||
