I am trying to communicate between my computer and an Arduino UNO board via Bluetooth. I made all the appropriate connections between the Bluetooth and the Arduino (Rx->Tx, Tx->Rx, VCC and GND). I uploaded a very simple code on the Arduino board (When I press a 1, the LED connected through pin 13 should turn ON and when I press a 0 it should turn off). I tried this code on the Serial Monitor of the Arduino program and it works perfectly fine !
The problem is when I use the Putty program to send commands, nothing happens when I press 1 or 0. I've been trying to troubleshoot this issue for a week approximately and I can't figure out the problem.
If there is anyone who can help me solve this issue, I would be very glad and appreciated !!
Thank You !!
