TUTORIAL: How to Program ESP8266 ESP-01 Module with Arduino UNO

We are going to see how to program ESP8266 ESP-01 module using an Arduino UNO with few very simple steps.

Note:

Download and install Blynk libraries to your Arduino IDE its very important before programming (Search on YouTube you can find easily).

Step 1:

Connections for programming

ESP8266:————– >Arduino:

GND ————————– GND

GPIO-2 ————————– Not connected (open)

GPIO-0 ————————– GND

RXD ————————– RX

TXD ————————– TX

CHPD ———————— 3.3V

RST ————————– Not connected (open) *(Read Below Instruction)

VCC ————————– 3.3V

Very Important Instruction:

Now before hitting upload, take GPIO-0 to ground.

And RST to ground afterwards, remove RST after half a second (the blue LED flashes for some millisecond).

Hit upload, the blue flashes once and then blinks till it gets uploaded.

Now you are all done.

Programming Procedure ESP-01 with ARDUINO UNO R3

Step 2:

After programming, remove the serial Arduino cable and plug it again and take out GPIO-0 from GND and just interchange the connection of RX and TX that is RX connect to TX and TX connect to RX.

Connections after programming

ESP8266:————– >Arduino:

GND ————————– GND

GPIO-2 ————————– Not connected (open)

GPIO-0 ————————– Not connected (open)

RXD ————————– TX

TXD ————————– RX

CHPD ———————— 3.3V

RST ————————– Not connected (open)

VCC ————————– 3.3V

After Programming Connections ESP01 with arduino uno Maroc — After Programming Connections.

That’s it, you are done!!!

Open serial monitor of Arduino IDE where you see the ESP is connected and ready.
