Wi-Fi Kontrollü Araba Uygulaması NodeMCU 1.0 (ESP-12E) ve ESP32 kodu
Görseldeki Wi-Fi kontrollü araba uygulamasında NodeMCU acces point (AP) modunda çalışmaktadır. NodeMCU’ya bağlanmak için kablosuz ağlardan “Robot” seçilir. Şifre “12345678” girilir. Bilgisayar veya akıllı telefondan tarayıcı (Chrome vb.) açılarak adres satırına 192.168.4.1 girilerek NodeMCU içindeki web server sayfasından araç kontrol edilir.
