hey there i amtrying to make my RC car into a "robot" driving rc car so that it follows a given path 
anyways i have found and determined the IC in the receiver and it is this one right here:
http://www.nxp.com/documents/data_sheet/HEF4515B_CNV.pdf
but its so much more complicated in the tutorials since mine has vss and vdd etc where his had left right vcc for voltage and ground was gnd etc but idk where the ground for my chip is etc
any ideas what the ground is on my chip or where the "vcc" is ?
i really need help with this so please help me out
Vdd is the positive voltage input and Vss is ground.
I am not sure how your question relates to the topic title.
yea sorry i didn't actually know how to title it but anyways thanks 
now i can try and send HIGH signals to the other pins and see if my RC car reacts to it ;D

There is a bit more to it thatn that.
You need to put a pattern on A0 to A3. Then put the EL line at 0 or one, then you need to pulse the E bar line.
yea i did some hardware research a.k.a looking at the chip lol and i got it out of the casing and there was no pins underneath the board and the IC is so tiny that soldering to its feets will be impossibru O.o so i was thinking if there could be other solutions and then i thought that i maybe could send an RC signal to the car from the arduino and then the car reacts to that signal ?
The only think you have posted is a link to a logic chip. There is a whole lot of something else you are keeping to yourself.
