Thank you, I'm glad you liked it.
All the six blue arrows in the diagram are leading to the pins of the L293D board as per the marking. For e.g RPi's GPIO 14 is connected to pin with M2-A marking on the L293D board. Similarly other pins have to be connected. So, there are 3 connections for each motor. One for speed control and other two for direction control. In the picture, only one motor is connected. The two connections (yellow and grey) are for direction control. Speed control wire is not connected in the photo. |
