Diagram Arduino Wiring Esp8266. Powering up the arduino and esp8266 setup. Connect the middle pin which is 5v input to the 5v output pin of the arduino.
The wiring of the ina219 is shown in the following pictures for different arduino esp8266 and esp32 microcontroller. The wiring is very similar to the ftdi. Male to male jumpers4.
And if youre playing along at home like i am as i write then here is a photo of the physical board.
Connect the power supply pins of arduino ie. Out of the box your wifi module needs to be configured to communicate with the ardiunouse the circuit diagram given below to set up the system. Connections are fairly simple. To energise the four coils of the stepper motor we are using the digital pins 8910 and 11.
