Sensor data not read when run Blynk.begin Solved

The ESP32 has two analog to digital converters (ADCs) One of these (ADC2) cannot be used at the same time as WIFi. The GPIO that you’ve chosen to use (GPIO4) … is attached to ADC2, so can’t be used at same time as other libraries that use WiFi (including Blynk). The solution is to use a pin that is connected to ADC1…. ADC1_CH0 (GPIO 36) ADC1_CH1 (GPIO 37) ADC1_CH2 (GPIO 38) ADC1_CH3 (GPIO 39) ADC1_CH4 (GPIO 32) ADC1_CH5 (GPIO 33) ADC1_CH6 (GPIO 34) ADC1_CH7 (GPIO 35) ADC2_CH0 (GPIO 4) ADC…
