My apologies if this is in the wrong section, seems general enough, hope someone can lend a hand. Ive lurked for a couple weeks now inbetween work and hobby time, ive recently got into the micro controller world and have ran into a stumbling block that i my google skills have failed to help with.
I have a couple projects in mind, but after going through the 'beginner' lessons i got to a point of trying something new. Ive coded an Android app that talks over the inter webs to a server script that serially communicates with the board that currently has lahzers representing the f/b/l/r controls. Thats all fine and dandy, my problem lies on my next step. I have a cheap R/C i purchased in hopes to control first the transmitter then ill wirelessly  build a bot as my next goal. The thing is, the transmitter is nothing like ive found in any tutorials ive came across, the hard part is.. there is no visible circuts on the back. im unsure how to send my signal from the arduino controlled board to the transmitter. The only thing ive successfully done is bridge the buttons to generate the signal.

Im already in the plans of finding a replacement R/C that will be a bit better, but for the time being im wondering if its even possible to pass a signal to this board, let alone solder anything to it to have a 'permanent' attachment to the receiver. 

Im a bit of a newb in this sense, i have done very little circuitry work, im currently in the software development field. I find this stuff facinating and would love to expand these new skills further to something more useful.
Any help is appreciated, or if needing more info please let me know!!
Thank you!

That is because the board uses surface-mount components, which means the actual circuit is on the front.
Oh, and it might be advisable to not use 8 Mpx pictures on the web. They take time to load and are difficult to look at on computer screens without manually sclaing them.

Alrighty, I posted from phone and let that big for detail, I've seen other with same size photo never seen a complaint, loads fine for me, I will keep image size in mind. On the other note, thank you, I didn't realize there was a surfAce mount board, now to figure how to solder the thing. Still not sure how to figure what   kinda signal to send it though. I'm going to get multimeter today and start poking around

Looks each of the four control buttons ground a pin on the chip. 1=Left, 4=Forward, 5=Back, 14=Right?

Correct, thats what i originally thought, but when trying to send a digital signal both high and low i dont get any results. it was odd, if i plugged two wires into arduino one for pin and other for hot or gnd and touch them respectively to the pins and to hot/gnd i would get a signal, even if the second wire was connected to another pin on the arduino. I know im not understanding this properly, which is why im researching, but so far i have failed to answer my questions. If you have any other id advice id gladly take it!
Thank you guys for the replies!
