Software Serial Library is used to allow serial communication on pin 2 and 3 of Arduino. Tx and Rx pins of ESP8266 are directly connected to pin 2 and 3 of Arduino. ESP8266’s Vcc and GND pins are directly connected to 3.3V and GND of Arduino and CH_PD is also connected with 3.3V. We mainly need a Arduino and ESP8266 Wi-Fi module. After it press Play button at the right top of screen.Īll this process, of using the Blynk App, has been clearly explained in Video, given in the end.Ĭircuit Diagram of Wi-Fi controlled robot is given below.
Then click on create button in Blynk app.ħ. Now Select the Joystick Widget, Click on Joystick, Configure the Joystick (see the Video at the end) and hit the back button.Ĩ. You should get Auth Token in the Blynk App.
Note down the Auth Token Code or simply mail it to your Email Account and then copy and paste in Arduino sketch (Program Code).ĥ. Enter this Auth Token Code in Arduino sketch. Now select Arduino Board and give a name for your project.Ĥ. You may use your current Gmail account.ģ. After this, it is required to create an account.
First download it from Google Play Store and install it in Android mobile phone.Ģ. This App can be downloaded from the Google Play Store, and can be easily configured.ġ. Blynk is a very compatible app with Arduino, to make IoT based project. Firmware version, good or bad is different, the public version of the firmware to governor jumper two steps of the governor, inconvenient and speed rating we have carefully selected and modified the firmware to achieve multi-level automatic speed control.Īn example: AVR microcontroller factory was a 1MHz internal oscillator circuit, then the firmware with a lower speed automatically download its download about 4K program shall 3 seconds for the same model using an external 12MHz crystal microcontroller, the clock speed up can support higher download speed, download the same program, the firmware automatically accelerated, the download only to be less than one second.For demonstration of Wi-Fi Controlled Robot, we have used an Android Mobile App named “ Blynk”. USBASP and parallel port download cable, and its internal firmware. 10-pin isp socket mount one on the board, on the one hand, space-saving and beautiful, the most critical is not with the multiple plug and loose.special carefully selected firmware super automatic speed control function, to obtain the best balance between stability and speed! PCB in accordance with the standards of high-speed board design, first-class stability. Hardware circuit design, does not simplify out any effect on the stability of the devices, especially the 3.6V regulator is determined not to province, to ensure that the level matching. * specifically designed for notebook computers, the ad hoc two 3.6V regulator, a perfect match, get rid of the hidden dangers of instability of the hardware circuit level! When the lifting of the short-circuit, self-resettable fuse will automatically return to normal conditions, the programmer can continue normal use! When the output current is greater than 500 mA (overcurrent or short circuit), will immediately cut off the current resettable fuse to protect the computer motherboard.
USB power port plus a 500 mA self resettable fuse to prevent damage to the computer USB port (USB port over current protection, but more than a protection more secure). USB interface for 5V power to download and target board, in case short-circuited, computer motherboard dangerous.
