Building and Controlling a Robot with ESP32 and Android App
Learn how to make a robot using ESP32 and control it with an Android app. Program the ESP using t note for esp32. Stop, move backward, right, and left functions are demonstrated with web interface and buttons.
00:00:00 Learn how to make a robot using an ESP32 and control it with an Android app. Connect the motor shield and program the ESP using t note for esp32. No sponsorships or brand names mentioned.
🤖 The video explains how to create a robot using an ESP32 and control it with an Android app.
🔌 Components needed for the robot include two wheels and motors, a motor shield, and a power bank with USB outputs.
👨💻 The ESP32 is programmed as a web server and receives incoming requests through HTTP.
00:02:11 Create a function to stop the robot and set all connected pins to low. Invert motor connections for backward movement.
💡 The video discusses how to create a function to stop a robot.
⚙️ To stop the robot, all connected pins need to be set to low.
↔️ To move the robot forward, one of the motor pins needs to be set to high and the other to low.
00:04:25 Inverting the forward function allows us to complete the right and left functions in our main program, finishing the five if statement with our functions. Uploading the M program to see the results.
🔄 The main task is to invert the forward function.
🔚 Complete the right and left functions.
☑️ Ensure the completion of the five if statements using the functions.
📥 Upload the M program to see the results.
00:07:58 The video demonstrates testing ESP, creating an Android app with four buttons and a web interface.

💻 Making a mistake in the code for the answer block
📱 Creating an Android app with buttons
00:11:19 The video demonstrates how to use the forward button to send an HTTP request and the stop button to send a stop command. It also explains the usage of other buttons.
🔘 Clicking the forward button sends an HTTP request with the word 'forward'
⏭️ Releasing the forward button sends a stop command
🔲 Other buttons can be configured in a similar way
