A breadboard is a great tool for quickly testing out a prototype circuit or hooking up a quick experiment. I’ll layout only the lateral position of the mortise- the vertical position isn’t an exact science as long as I keep it the same across both breadboard end and panel. This will give you a chance to double-check all your connections before you turn your circuit on for the first time. This picture above shows a typical breadboard with a 7805 5-Volt voltage regulator mounted on it. There are several rows of holes for components.
A virtual breadboard is also called as VBB and makes use of microcontrollers featuring Makeable bereadbaord designs. In person, if you look closely from above, you can see the metal strips inside of the breadboard. Since old bread boards have a primitive shape, draw designs freehand without worrying too much about perfect symmetry. After cutting the joinery for my bread board end, I didn’t even bother to sweep or vacuum my bench or shop floor, there simply was nothing left behind due to the superb dust collection from the Festool system.
This picture shows it hurdling the center line but the top and bottom pins are connected when the button is pushed rather than the left and right. As long as all the electrical connections are being made, you can build your circuit any way you’d like! This circuit diagram tells us (clockwise from the battery): Connect the positive terminal of the battery (red battery clip lead) to the 1 kilo-ohm resistor.
An example of such a board is shown here, this unit actually a power supply” circuit designed to take 120 volt alternating current (AC) power from a household wall socket and transform it into low-voltage direct current (DC). If you have a breadboard with binding posts, make sure to verify this before you use them. You can probably make these without a breadboard but it makes it so much easier.
Now let’s look again at the YourDuinoRobo1 board and where we will make connections there. Insert a wire connector into a hole directly below the resistor lead and into the bottom rail of the breadboard. These are also helpful when using instruction booklets, such as the one found in the SparkFun Inventor’s Kit Many books and guides have circuit diagrams for you to follow along while building your circuit.
SparkFun Electronics and Electronix Express () sell a slightly smaller 270-point solderless breadboard for $6 (PRT-00137) and $2.70 (03MB101). By the time students reach the limitations of the springboard, they’ll be ready to move onto a breadboard and expand their repertoire. Be forewarned that the quality of this breadboard would be not as good as a real one.
