I am using Atmel's ATmega 16. I have to interface an Ultrasonic sensor(with two switches to vary the distance of ultrasonic sensor) and a RFID module and an lcd and a motor driver L293D. kindly suggest me how to make connections wisely.

@nitinkanwar1402, Welcome to EasyEDA. It is impossible to answer such broad questions without more information about what you are trying to design. You might find it helpful to sketch up an outline of your design using the Drawing Tools and to write a specification for your project simply by inserting Text into that drawing or on a separate sheet. You are also strongly advised to use the power of the internet to search for information about the various aspects of your project that you have mentioned here and in your other post: https://easyeda.com/forum/topic/H_bridge_through_relays_or_L293D-5NK6sOawf By presenting that sort of information and otherwise demonstrating that you have done some serious research for yourself - rather than the approach you are using right now, which amounts to just asking people to give up their time to design your project for you - you may be able to get more help from other users. For example, with only a very quick search for L293: The datasheet for the L293D is quite useful and informative: http://www.ti.com/lit/ds/symlink/l293.pdf You can learn a lot from things like this: http://www.st.com/web/catalog/sense_power/FM142/CL851/SC1790/SS1555/PF63141# https://learn.adafruit.com/adafruit-raspberry-pi-lesson-9-controlling-a-dc-motor/lm293d Similarly, you will find much information about all the functions that you have asked about. If you are interested , you will find a simulation of - and links to more information about - the Intersil HIP4080 H-Bridge driver here: https://easyeda.com/andyfierman/Demonstrating_the_EasyEDA_HIP4080AEE_spice_model-j7D92ysKE You could use that to play around with H-Bridge motor driving. :)
