So I'm planning on building a skee ball machine and as I've been looking into it I've decided to use some seven segment displays from here:

7-segments display

As I've looked into this more I know I need a breadboard and I'm planning on using a solderless one found here


So my plan is to use an arduino to get input from the arcade machine and then hook up a raspberry pi to get information to the bread board and light up these displays (I'll have 7 seven segment displays, so I have enough to have the word "highscore" on display at one time).

I'm fairly new to this breadboard thing and want to know what wires I would need to connect these SSD (seven segment displays) to the breadboard. I've found a couple of different wires and they're all confusing me.

Here's the first one:


My fears with this one are:

  1. Will they be long enough, they look rather short. 2. Are they even the right type to connect

Here's the second one:

Jumpers 2

My fears with this one are:

  1. What's the difference between the male and female ends compared to my first one?
  2. Will this one work?

So I'm really confused on which ones work and would appreciate some help and guidance and hopefully gain some knowledge of this.

  • \$\begingroup\$ You solder the wires to the segments, not the breadboard. \$\endgroup\$ Mar 20, 2014 at 14:50
  • \$\begingroup\$ OK, but i still would rather not, if it is absolutely necessary i will, but I'd prefer not \$\endgroup\$

The wires you show are meant for both ends to be connected to the breadboard. They have nice and sturdy pins on the ends that are just right for the sockets in the breadboard.

However, if you want to connect points on the breadboard to something off the breadboard, like your 7-segment LEDs apparently, then these aren't appropriate. Fortunately single strand #22 wire works just fine in these breadboards too. Get a roll of it, cut each wire to the length you need, solder one end to the LEDs, then stick the other end into whatever socket in the breadboard you want.
