R11e(Circuit board)

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.
