Hc 05 with arduino

[awais110565]

i want to control motor with hc 05 wirless and mega 2560 , i want to know that do i need to make voltage divider while connecting hc 05 with arduino or i can connect hc 05 directly with arduino mega?

Thank you

You do need a voltage divider between the Tx of the Mega and the Rx of the HC-05.

And some additional advice just in case: do not use SoftwareSerial if you don't have to; the Mega has three spare serial ports.

Thank you very much for your kind reply , i want to control linear actuator , please can you see the figure and point of mistakes if made.. Thank you very much

The resistors are 1kohm and 2kohm so i will get 3.33V at the end to hc05
