Circuit board |
|
| Circuit board can be aluminum tape and thick paper, in batteries and light-emitting diode. You do not need any special tools and technology to work. |
|
 |
|
|
| Has the following features to the circuit board, a variety of work can be done depending on the device. |
|
| ・And compare with the schematic is easy. |
| ・Because instead of lead, is being used to lead the metal body having a width in the bare, it is easy to aware of the passage of electricity. |
| ・By using the light-emitting diodes, it is easy to sense the polarity of the electricity. |
| ・Battery box since it is possible to expand the same plane as the circuit, the battery box is not a black box. |
| ・Tool itself is a relatively simple and do not use special tools to manufacture. |
| ・Degree of freedom that can be changing the number of light-emitting diode or add switch is large. It can also be developed into an arts and crafts activity basis. |
| ・The including a light emitting diode, is used in the live familiar material. |
