o Simple LED blinking using Arduino Mega 2560 and Bluetooth module HC-05: o Components: Arduino Mega 2560 (x1) Bluetooth Module HC-05 (x1) LED (x3) 10-ohm Resistance (x3) Jumper Wire (As per Required) o Circuit Diagram: o Connection: Ø Take an Arduino Mega 2560/Uno, then take Bluetooth module HC-05. Ø Now connect the VCC terminal of the HC-05 to 5V Terminal of Arduino and connect ground (GND) terminal of HC-05 to GND terminal of Arduino. Ø Now connect RXD pin of HC-05 to TX0>1 Terminal of Arduino. Ø Now connect TXD pin of HC-05 to RX0>0 Terminal of Arduino. Ø Here we take pin no 11,12 and 13 of Arduino as a output pin so connect 11,12 and 13 pin with 10 ohm resistance of LED 1, LED 2 and LED 3. Ø Now connect this resistance with positive (Long leg) of LED. Ø And finally give common ground to all LEDs with GND terminal of Arduino. o ...
