# Arduino Bluetooth Flasher

Arduino programming with Bluetooth using ESP32 makes it easy to upload code to Arduino without any problems with the serial port.

# Wiring

| ESP32 PIN   | LOGIC LEVEL CONVERTER | ARDUINO PIN |

|:-----------:|:---------------------:|:-----------:|

| RX          | LV1 <------> HV1      | TX          |

| TX          | LV2 <------> HV2      | RX          |

| 3V3         | LV  <------> HV       | 5V          |
