i'm wondering when to use a female jumper wire or a male jumper wire. I have purchased myself a netduino 2 microcontroller and also an LCD screen plus an ultrasonic sensor. But the problem is i want to connect these devices but don't know which jumper wire to purchase before i can connect my netduino to the sensor or the LCD.

Help pls....

i basically want to develop an obstacle detector. Which netduino board will suit ma goal. i will also be using an ultrasonic laser sensor to inspect the environment for obstacles, will also use and LCD display message and also be needing a sound output too. Pls help!!
