refer this link for the interface and use custom character to create shapes.
Prabakaran P MParticipantPlease give the specs of colour sensor for better answering of this question.
Prabakaran P MParticipantPrabakaran P MParticipantProGFX engine is the library available for interfacing 128*64 lcd with atmega 32. make use of it guidelines are available in the download page.
Prabakaran P MParticipantHi Dhananjaya,
For giving you idea in this topic i need the circuit diagram of the voltage divider circuit you used. coding logic is correct. Use diodes and voltage divider to ac voltage to dc voltage. Because Pic microcontroller can only read the dc voltage logics.

you can refer to this page for transformerless ac to dc convertion.
Note: Ac live Voltage will be found all over the circuit so be safe while doing these type of projects.
June 15, 2015 at 4:28 am in reply to: Is that integer size would be differ for every 16bit, 32bit controller?? #12985Prabakaran P MParticipantFor your first question my answer is yes.
For doing 32bit operation in 16 bit controller you can use double int are manually create a library which will do 32bit operations using 16bit instructions.
Mainly integer size is based on the compilers it will vary according to the compilers. Assume two different compilers can have different int size for a same microcontroller and vice versa.
you have to see the types defined in stdint.h, or otherwise gothrough the documentation of the compiler.
Prabakaran P MParticipantTry zigbee for your transmission and reception of data,and accelerometer for the sensing of moves.
June 10, 2015 at 6:53 am in reply to: solid-state on/off control of 12V circuit using 6V circuit #12971Prabakaran P MParticipantUse TIP122 or any other transistors according to your current flowing in you 12v circuit.
Prabakaran P MParticipanthttp://www.engineersgarage.com/forums/pic/using-timer0-counter-mode-pic18f4550 Refer this link for ur query.
Prabakaran P MParticipantGFX library (courtesy of Adafruit)
Refer to this library for making analog or digital clock.
Prabakaran P MParticipantFor what purpose you are choosing this controller.
Prabakaran P MParticipantFirst of all give me details about the avr varient you are going to choose. If you are not sure u can use Arduino TRE which is enabled with HDMI output.
Prabakaran P MParticipantYou have to go through the basics of your project. these links will be helping you.

you can also use DTMF Decoder circuit to controll your CAR.
Prabakaran P MParticipantyou can refer these links to get started with your project,
