57. Using Blynk with Arduino Uno and ESP8266 WiFi module

Hello Everyone!
Today I am going to explain you how to connect your Arduino Uno with Blynk using the ESP8266 WiFi module. I have already demonstrated you about connecting your Arduino Uno with Blynk app using the Ethernet Shield W5100 and this will be the second version of that project. 

Hardware components used in this project

  • Arduino Uno
  • ESP-01 ESP8266 WiFi module
  • USB to TTL converter
  • Solderless Breadboard - Half+
  • Breadboard power supply module - 3.3V/ 5V
  • RGB LEDs (x3) - Common Anode
  • Resistors (x3) - 220Ω
  • Relay module - 5V single channel
  • Male-to-Male Jumper wires
  • Female-to-Male Jumper wires

Setup


Your setup must look somewhat similar to that shown in the images above.

Connections

ESP8266 ESP-01 wifi module

  • GND - Ground
  • GPIO0- Not connected
  • GPIO2 - Not connected
  • RXD - D2
  • TXD - D3
  • CH_PD - VCC - 3.3V
  • RESET - Not connected
  • VCC - 3.3V 
*Note: Do not connect your ESP8266 ESP-01 wifi module with 5V.

RGB LED - Common Anode

  • Anode - 5V
  • Red - D9
  • Green - D10
  • Blue - D11

Relay module - 5V single channel

  • S - D7
  • (+) - 5V
  • (-) - Ground

Coding

My ESP8266 ESP-01 came with the latest firmware so it did not require flashing. I used the USB to TTL converter and AT commands to add my WiFi credentials to my ESP8266 ESP-01 WiFi module. For this project, you will be needing the Blynk app. To get started with Blynk, please visit this link:
Use the example code builder to choose your hardware model and connectivity type, and copy the whole code to buffer.
Upload this code to your Microcontroller board and connect your board with Blynk app.
Create four buttons on your Blynk app to control your relay module, red, green and blue LEDs. Watch the YouTube video in the last section of this page to learn how this works.

Final Look

      Could you elaborate the difficulty your are facing? Have you checked your connections?

51. Buzz wire game using Arduino

Hello everyone! This is my first Arduino project in 2020 and it is going to be a fun and simple project. You would have heard of the Buzz Wire, a steady hand game, and today you will be learning to make one using Arduino. Hardware components used in this project Arduino Nano USB Type A to mini B cable (for Arduino Nano) Solderless Breadboard - Mini and Full-size LEDs (x2) - Green and Red Resistors (x2) - 220 Ω  Active Buzzer module (KY-012) LCD display module with I2C interface - 16x2 Male-to-Male Jumper wires (x4) - 10cm Female-to-Male Jumper wires (x5) - 20 cm Jumpers (x5) - to reduce the usage of wires Copper wire  Tape (or any form of insulation)  Setup Your hardware setup must look somewhat similar to the ones in the images above. The beginning and end of the copper wire maze must be taped to prevent conductivity between the wire loop and maze. Connections LCD display module with I2C interface GND - Ground VCC - 5V SDA - A4 SCL - A5
