3//   Pico W IoT Motion Counter (PIR)
4// ─────────────────────────────────────────
5// The "Motion detector" IoT template from the BlueGrays app: when the PIR
6// sensor sees movement the board tells the app at once, counts every new
7// movement, and the counter builds up in a chart in the app; the Reset
8// counter button sets it back to 0. Ohmi prepares the real code in the app
9// with your own device key (Workshop › Devices › Add a device); the code
10// here is an example, the device key and Wi-Fi details are placeholders.
11// Library Manager: BlueGraysIoT (with its dependencies). In Arduino IDE
12// pick Raspberry Pi Pico W as the board (pico package). The board only
13// joins 2.4 GHz Wi-Fi networks. The PIR sensor needs about 1 minute to
14// warm up after power-on; it may miscount during that time.
15//
16// Pins:
17//   GP13 -> PIR sensor OUT
18//   VBUS (5V), GND -> PIR sensor VCC, GND
19//   ESP32: PIR OUT GPIO33, VCC 5V
