Using PIR Motion Sensor HC-SR501 with Raspberry Pi Model 3

[r3rivera]

I've been trying to use the example provided https://gobot.io/documentation/drivers/pir-motion-sensor/ but used a different pin. The code can be found in https://play.golang.org/p/f1UQDG1htvP

However, using the /dev/ttyACM0 gives me an error saying that the directory is not found. it looks like most of the search result is pointing to Arduino. I checked /dev/ folder and the one that I can see that close enough is /dev/ttyS0 and /dev/ttyAMA0.

I tried both but it gives me the error of :

• unable to connect. Perhaps you need to flash your Arduino with Firmata?

Nevermind. I just used the default raspi driver. https://play.golang.org/p/TTQDDMgNN0W
