Need Help
Guys I have been working on a voice controlled car. I bought a L293D motor driver module and mounted it on Arduino mega. It was only connected to 4 TT motors and the led on it turned on but after I connected all the other components like ultrasonic sensor, HCO5 Bluetooth module and a servo motor it's led Is not lighting up. I'm powering it using 2 18650 Lithium ion batteries. The Arduino works and even the ultrasonic sensor and Bluetooth module works when I plug in the Arduino into my laptop but the L293D doesn't. I tried charging the batteries more but it didn't work either. Pls can someone help it's my first time making something.
