Control Anything Anywhere without Internet with Arduino, Learn how to make your own Arduino Wireless long distance Controller via DTMF Decoding without the Internet, WiFi or Bluetooth!! Have you ever needed to control a device, sensor, or a project from a long-distance location that doesn’t have Internet? Are you tired of using Radio, WiFi, or Bluetooth modules that cost a lot and have a limited range, plus the programming pain that comes with them? If yes, then you have come to the right place. In this course, we’ll introduce the DTMF technique that will give your simple Arduino board superpowers. With DTMF, you can control anything, anywhere with a simple, cost-effective solution. In this course, you will learn how to write a very simple code to control multiple devices in an easy way. You’ll also discover how to create robot algorithms using the Robot Operating System (ROS), integrate multiple sensor inputs and actuators with Arduino, and use ROS’s powerful features for your own robotics projects. DTMF makes programming easier, saves time in development, and eliminates the need for extra Bluetooth, WiFi, or RF modules. You’ll learn to program Arduino using Arduino IDE, make your own DTMF Decoder, interface it with Arduino, design a DTMF Decoder PCB with Eagle, simulate your circuit with TinkerCad, and create a 3D case for your project board using Fusion 360. By the end of this course, you’ll be able to control devices wirelessly over long distances without the Internet, WiFi, or Bluetooth, and you’ll have practical skills in electronics, PCB design, and 3D modeling. The main objective of this course is to introduce TinyML development from data collection, model training, testing and deployment. A low-cost Arduino nano RP2040 connect board with 265 KB RAM and 16 MB flash along with accelerometer, gyroscope, microphone, temperature sensor and built-in wireless connectivity module (WiFi+Bluetooth) is used in this course and all the examples shown here have been tested on this board.
