Switch Design of Half-wave Heating Electric Blanket Based on 555 Timer

Generally,the heating method of electric blanket in the market is full- wave heating,and the heating temperature is controlled with different gears. It need shift the switch manually,which results in the temperature too high after a long time using which may reduce the sleep quality. To overcome this disadvantage,a half- wave heating electric blanket switch was designed based on 555 timer. The key elements in this switch are the multivibrator...
