Sistema de automação de baixo custo com CI 555 para a acessibilidade

Accessibility for disabled people in general is a constant concern in the last decades, developing ideas or products to make the use of safe, collective places, and providing autonomy to those who need it, is a direct benefit to society. Was thinking about it that the basis of this work was to develop a prototype electronic circuit simple and easy to reproduce, which through infrared radiation, enables the remote activation of day to day equipment such as fans, lamps, among others. The technology used to develop the prototype was the 555 integrated circuit, easily found in any electronics store, and at the lowest possible cost. The results obtained were close to the expected, the prototype behaved stable in the tests performed, presenting low energy consumption, which allows its use without additional costs.
