Getting Started With ESP32

ESP32 is a single 2.4 GHz Wi-Fi-and-Bluetooth combo chip designed with the TSMC low-power 40 nm technology. It is designed to achieve the best power and RF performance, showing robustness, versatility and reliability in a wide variety of applications and power scenarios. The ESP32 series of chips includes ESP32-D0WD-V3, ESP32-D0WDR2-V3, ESP32-U4WDH, ESP32-S0WD (NRND), ESP32-D0WDQ6-V3 (NRND), ESP32-D0WD (NRND), and ESP32-D0WDQ6 (NRND), among which,
• ESP32-S0WD (NRND), ESP32-D0WD (NRND), and ESP32-D0WDQ6 (NRND) are based on chip revision v1 or chip revision v1.1.
• ESP32-D0WD-V3, ESP32-D0WDR2-V3, ESP32-U4WDH, and ESP32-D0WDQ6-V3 (NRND) are based on chip revision v3.0 or chip revision v3.1.

Pinout of ESP32

Step1:- Program ESP32 with Arduino IDE

Install Arduino IDE with this link – https://www.arduino.cc/en/donate/

click on just download and install it in your pc

Step 2:- Install ESP32 in ArduinoIDE

Click on file >> Preferences

For ESP32

Copy this link and add to additional board manager and click ok

https://dl.espressif.com/dl/package_esp32_index.json

GoTo tools >>Board: >> Board manager

Search for ESP32 and Install it.

For ESP8266 board add this link below —

http://arduino.esp8266.com/stable/package_esp8266com_index.json

Goto >> File >> Preferences >>paste link and click ok

Goto >> Tools board>> board manager >> Search for ESP8266

Restart your ArduinoIDE

Click on Tools >> Board >> ESP32 Arduino >> select your board >> now you are good to Go

Start with basic blinking program

Click on file >> Examples>> Basics >> Blink

Now Replace LED_BUILTIN with pin no. 2 because inbuild LED is attach with pin no. 2 in ESP32 module
BY just – press ctrl+F cand to pin no 2 click on replace all.

Now select Port
cilck on tools >> port >> select port

Press the upload button

If there is problem is uploading code or just showing connecting ……._____….

Press and hold boot button in your ESP board for a second and release Repeat this process until it shows Uploading data like this >>

See if you board’s LED start blinking Congratulation you are done test your Board and ready to make different projects.
