Hi sarah, we would like to do an IoT project exactly like the one you mentioned, but we want to add buzzer and use blynk for notifications, do you might know how to do it ?
Best regards,
Lily

Hi.
Take a look at this web server with sensor readings. Instead of the sensor readings, you’ll display the counter variable: https://randomnerdtutorials.com/esp32-dht11-dht22-temperature-humidity-web-server-arduino-ide/
However, this kind of web server is a bit advanced for just displaying the counter.

Hi Sara,
First Happy Newyear!!
Currently I’m working on a birdhouse with webcamera for my little son.
I want to use the PIR code for bird detection in a “counter” ( instead of your LED). Just to detect if there is any activity in the birdhouse.
I want to run your PIR code together with the “ESP32-CAM Video Streaming Web Server” and have the “counter” value represented in the camera webserver-website…
Main headache for now is how to handover the “counter” value to the camera webserver. Any idea how to accomplish this?
THX for your reply.

Hi.
We’re using GPIO 27. But, you can use any other suitable GPIO.
Check the ESP32 pinout: https://randomnerdtutorials.com/esp32-pinout-reference-gpios/

Unfortunately, we don’t have any tutorials dedicated specifically to that subject.

tks for the reply Sara as ‘ The Wi-Fi should not interfere with the timers’

Altough, I see otherwise.

Will continue my search

Do you have a sample code that uses timers and wifi ?

Hello Random Nerd, excellent article, as usual.
Using timer for the first time with esp32 and following your article, works real good until I enable esp-now ( or the wifi ) .
is it possible to get a precise timer running with the WiFi ( or esp-now ) ??
if yes , how.

tks
