Interrupt for motion sensor

Hey guys, I would use a motion sensor to detect the presence from my cat. The sensor gives me a HIGH signal when something is detected and in case of nothing detected a LOW signal. Now I thought, it should work a interrupt. I don´t know, the example from sketchbuilder doesn´t work… #define BLYNK_PRINT Serial #include <ESP8266WiFi.h> #include <BlynkSimpleEsp8266.h> char auth[] = "xxxxxxxxxxxxxxxxxxxxxxxx"; char ssid[] = "xxxxxxxxxxx"; char pass[] = "xxxxxxxxxxxxxxxxxxxxxxx"; Widget…

I think your interrupt service routine (ISR) creates problems (watchdog resets, etc…). Please research how to write a better ISR. The code hereafter is just the some suggestion to fix the issues: Pls pay attention to the volatile variables using inside ISRs, which must be very short. Then use a timer to check the flags set by ISRs. #define BLYNK_PRINT Serial #include <WiFi.h> #include <WiFiClient.h> #include <BlynkSimpleEsp32.h> int threshold = 10; int notif = 0; int lastnotif = 0; Widget…
