We have seen various applications of IoT but what about adding the touch to it. In this 

project, we will add simple touch buttons to the ESP-32 Wi-Fi module. ESP-32 is a great module to design IoT applications and adding touch to it will make it further smart. Talking about ESP-32, it is a micro-controller designed by Espressif mainly for IoT applications. It is so handy that even a novice can use it. ESP-32 contains Wi-Fi, Bluetooth, Inbuilt Touch sensing input pins, temperature and hall sensors on board which makes it fit for IoT and Smart home.
