ESP32 has two 32-bit Tensilica Xtensa LX6 microprocessors which makes it a powerful dual-core (core0 and core1) microcontroller. It is available in two variants single-core and dual-core. But the dual-core variant is more popular because there is no significant price difference. ESP32 can be programmed using Arduino IDE, Espressif IDF, Lua RTOS, etc. While programming with Arduino IDE, the code only runs on Core1 because Core0 is already programmed for RF communication. But here is this tutorial we will show how to use both the cores of ESP32 to perform two operations simultaneously. Here the first task will be to blink the onboard LED and the second task will be to fetch the temperature data from the DHT11 sensor.
