| Research Abstract |
In the school for the visually impaired, two types of voltmeters are used for science lessons. The first is of an audio pronunciation type. The second one is of an analog type, having an exposed indicator needle. They were very expensive. In addition these meters have been discontinued. In this study, we developed a linear-cylinder-array-type voltmeter, which consists of a servomotor and a microcontroller. The cylinders project upward in proportion to the measured voltage.
