I have a circuit mapped out on a breadboard for adding wifi to an espresso machine via esp8266-01 and using the st_anything GitHub repos.
My problem is that the espresso machine uses a momentary button to trigger the machine on with a 5V pulse, which is easy enough. But the esp8266-01 module (or maybe other versions too) give off a short pulse on the gpio pins right when you first power up the module. This would be ok too but I don't want the machine to power up every time I plug it in or have a power outage when i'm not at home.
Is there a way to cut out that first little blip of power using a hardware solution? Some sort of filter that only gives an output if the gpio is on for 3 seconds or so? Or some other solution?
Thanks in advance.
