WebESP32 is a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth.The ESP32 series employs either a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations, Xtensa LX7 dual-core microprocessor or a single-core RISC-V microprocessor and includes built-in antenna … WebYou would be creating a short circuit if you just connect an LED without a series resistor. It also depends on your LED's forward voltage (Vf) which is a characteristic of the LED. If the LED's Vf over 3V, it won't turn on and nothing will happen. If it's under 3V and there's not a resistor, lots of current will go through, likely burning it. svart jacka dam zara
