If you are a beginner and you have never used the L298N motor driver then I highly recommend you should first watch this tutorial and then you can resume from here. In this tutorial, I also explained how to control the speed of a dc motor using the pulse width modulation.
Today’s tutorial is based on my previous tutorial, in this tutorial, I explained, how to assemble the robot parts and how to use the L298N motor driver to control the forward, left, right and reverse movement. While in the first version, I used an Android cell phone to control the Robot Car using the HC-05 Bluetooth module. The program used in this project was a little bit complex, so that’s why I decided to make another version of this robot and use a separate sensor for the speed controlling. While in the 3rd version, I used the flex sensor and the joystick together to control the same robot car, in this project the flex sensor was used as the accelerator and the joystick was used to control the car’s forward, left, right and reverse movement, I named this project a wireless hand gesture + joystick robot car… While in the 2nd version, I used only the joystick to control the speed and movement of the robot Car. in this project, the speed of the robot car is automatically adjusted depending on the distance between the cars. This is the 5th version of the Robot Car.while in the 4th version I used an ultrasonic sensor to make a safe distance maintaining robot car. I will make a separate video on how to use the IP cameras. For remote controlling, an IP camera can be used for live video streaming. The joystick widget will be used to control the Forward…Reverse….right …and left movement.while the slider widget will be used to control the speed of the dc motors in real-time…As this project is based on WIFI, it means this robot car can be controlled from anywhere around the world. Wifi Robot Car- In today’s tutorial, you will learn how to control a robot car using Arduino, Nodemcu esp8266 wifi module and Blynk application. Some other Projects based on the Nodemcu and Blynk Application:.wifi robot car Nodemcu esp8266 wifi module programming.
