Before we start with the first example, controlling an Arduino using a smartphone, let’s take a closer look at the HC-05 Bluetooth module. Comparing it to the HC-06 module, which can only be set as a Slave, the HC-05 can be set as Master as well which enables making a communicatio...
If you connected EN to +5 V, you may have fried your HC-05 module. When connecting signal inputs (including Rx and EN) to a 5 V Arduino output, the connections MUST to go through a voltage divider circuit (as Martyn has shown in his diagrams) or you risk damaging something. Also, ...
Step 6: Circuit You can refer to the picture for the circuit, the circuit is quite simple. Now we use the pins 32, VCC, GND, TX, RX of the HC05, we no longer require the KEY pin. The pin 32 of the HC05 is used as a reset pin for the Arduino, because the board resets auto...
We can easily do that by using AT commands, and I set the joystick to be a master and the Arduino robot car to be a slave. Here’s the complete circuit schematic for this example: You can get the components needed for this example from the links below:...

2. The HC-05 just refuses to respond sometimes when you type AT. Then it might respond Error(0). Keep persevering, it will eventually respond. 3. You have to be in AT-Mode to do any of this. I had to press the button on my module for a few seconds until the LED started to bl...
