Hi,
If you want to make Blynk2.0 Controlled Robot, then in this post you will get all the information step by step here.
So, you need the following components to make robot.
- NuttyFi/ NodeMCU ESP8266- 1 No
- L293D Motor Driver- 1 No
- Robot Wheels- 2 Nos
- DC Geared Motor- 2 Nos
- Robot Chassis- 1 No
- Free Wheel- 1 No
- 104 Ceramic Capacitor- 2 nos
And this is the video tutorial, where you will get all the information with live demo.
And,
This is the circuit diagram to control robot using NodeMCU, you have to connect all the connection as per this circuit diagram.
if you are using ESP32 board, then below is the circuit diagram.
Watch the full video on YouTube for the complete code and details. All relevant content is available in the video description.
