How do I connect to ESP8266 01?

How do I connect to ESP8266 01?

Plug your FTDI adaptor into your laptop, and grab a bunch of jumper wires, and go ahead and connect Rx pin of the ESP-01 to the Tx on the FTDI adaptor, and the Tx of the ESP-01 to the Rx on the adaptor. Then go on to connect the GND pin of the ESP-01 to the GND pin of the FTDI adaptor.

How do you reset a ESP-01 module?

Click Tools, Port, and select the port where the ESP-01 is connected. Finally, you are ready to program the ESP-01. Press and hold the Reset button, and then press and hold the Flash button. Release the Reset button, and while holding the Flash button pressed, click the Upload arrow in the Arduino IDE.

How do I connect my ESP 01 to WiFi?

To see if it works, open the Wi-Fi settings on your computer, look for a network called “ESP8266 Access Point”, enter the password “thereisnospoon”, and connect to it. Then open a terminal, and ping to 192.168. 4.1 (this is the default IP address of our ESP AP). You’ll see that the ESP responds to your pings.

How do I add code to ESP8266?

Step 1: Open the example blink program from the “example for NodeMCU 1.0” section inside the example menu, Step 2: Connect the NodeMCU with your computer using the micro USB cable. Step 3: Select and Board and Port and upload the program, that’s it, now the builtin LED should start blinking.

What are pins for shift register on ESP8266?

If you use an ESP8266 board I use the digital pins D0, D1 and D2 for the storage register and shift register clock input as well was the serial data input. For the ESP32 NodeMCU I use pin 21, 22 and 23 but you can use different digital pins if you like.

What are the pins for the shift register?

To control the shift register I use the digital pins D0, D1 and D2. The following picture shows the wiring between the ESP32 ESP-WROOM-32 and the 74hc595n shift register. For the power supply, you can use the 3.3V or 5V pin of the ESP32 microcontroller, because the operation voltage of the shift register is between 2V and 6V.

What’s the latch on an Arduino shift register?

The latch (STCP pin) is released HIGH to save the data in the register. The following pictures show the wiring between the most used Arduino, ESP8266 and ESP32 microcontroller and the 74hc595n as well as the LEDs and resistors.

What kind of power supply does an ESP32 need?

The following picture shows the wiring between the ESP32 ESP-WROOM-32 and the 74hc595n shift register. For the power supply, you can use the 3.3V or 5V pin of the ESP32 microcontroller, because the operation voltage of the shift register is between 2V and 6V. The ESP32 controls the shift register with three digital output pins that you can choose.
