Elektor Circuit: Touch Doorbell with 555
https://www.electronics-lab.com/elektor-circuit-touch-doorbell-with-555/
Idea: Elektor Lab The great advantage of a touch button or switch is the absence of mechanical parts — what is not in it cannot be broken. Because old-fashioned doorbell push buttons are exposed to wind and weather, they become unreliable over time. So why not replace them with a touch button? Figure 1 shows […]
