For testing or to try out an idea, temporary circuits can be built on a breadboard. Component replacement and connection changes are simple because no soldering is necessary. It may be quickly used to create a prototype of an electronic circuit and accepts almost any type of component, including transistors, diodes, LEDs, resistors, and capacitors. There is no need to solder. circuits are easily modifiable or revised Standard 2.54mm hole spacing and suitable for jumper wires 0.8mm in diameter Backside of the board with an adhesive sheet - You can also connect several breadboards together.
