First I am going to build an example project and then I’ll try to explain how it works and how you can replicate the Bluetooth communication. We'll be building a portable temperature sensor that sends a live feed to your smartphone. The build can run for days on a single li-po and ...

I already have tutorials on how to connect and use each of these modules with the Arduino board, so if you need more details you can always check them. The links to each of them can be found below in the article. Arduino Robot Car Control Using HC-05 Blu...
So the RX pin of the Arduino needs to be connected to the RX pin of the Bluetooth module, through the voltage divider, and the TX pin of the Arduino to the TX pin of the Bluetooth module. Now while holding the small button over the “EN” pin we need to power the mo...
This is the framework for almost every robot that we’ll work with. Modify it according to your need to use it as a line following, obstacle avoiding, light-tracking robot etc. Circuitry Of The Robot For this robot, we have to connect the HC-05 Bluetooth module HC05/HM10. In the ...
it to the Arduino Uno and also to the PCB board. When connecting the Bluetooth Module to the Arduino, make sure that the TX pin of the Bluetooth Module is connected to the RX pin of the Arduino and the Rx pin of the Bluetooth Module is connected to the TX pin of the Arduino. ...

board with built-in Wi-Fi and Bluetooth capabilities. ESP32 comes with an internal RTC, but its working is dependent on power. So if you want to design projects or circuits that you want to run even when there is no power, you must use any external RTC module like DS1307 or DS3231....
Those chips do not cost much more than an Arduino and there are tons of code snippets available. Another option would be to use a BlueTooth module that will connect with PushButton Authentication and write some software for your Android/iPhone or Server on your Netbook that connects via SPP ...
