I purchased a motor shield (L293D) and it doesn't have the female header which I can connect to another shield. What can I do to stack up more shields? For being more specific I ordered my shield from here: https://www.amazon.in/Simple-Labs-SLAEX039-Shield-Arduino/dp/B00K2Z3GAE/ref=sr_1_1?ie=UTF8&qid=1518767182&sr=8-1&keywords=motor+shield+for+arduino+uno&dpID=41h0ag2SCgL&preST=_SX342_QL70_&dpSrc=srch
And please tell me how to do it because it is new for me. A guide or something?
