Serial enabled device (a Xbee Radio, a Bluetooth® module, or RFID reader, or another board, for instance). 串口设备(例如:Xbee Radio、蓝牙模块、RFID 读卡器或者其他板子) (2)电路连接图 - Circuit After checking the data sheet of whatever serial enabled device you choose to use for this exa...
the device in Arduino Bluetooth rc car will get this character. and send it to the Microcontroller. we code this microcontroller like if the device get ‘A’ then the motor of the car will move forward. for backward direction of car there we can use...

we are moving towards the ESP32 Bluetooth low energy (BLE) and will see a practical example at Arduino IDE. In the previous session, along with all the basic concepts, I discussed the basics of ESP32 in the Arduino IDE and mentioned the introduction of E
今天我们介绍蓝牙通信的另一种方式--BLE(Bluetooth Low Energy,蓝牙低功耗)。 什么是BLE 在《无线通信3:HC05/HC06经典蓝牙BT模块》我们提到过经典蓝牙BT和蓝牙低功耗BLE的区别。顾名思义,低功耗蓝牙追求的是极低的功耗,它的主要应用场景是短距离、少数据量的传输场景,不像经典蓝牙那样通信时要一直保持连接,BLE可...
