Flip-Flop troubleshooting + wiring Transistor to control RC car

-

hey guys.  i'm working on building car starts / stops moving when exposed light.  i've got circuit set detect voltage corresponding light intensity, compare threshold voltage, , toggle flip-flop when detects pulse.  flip-flop (increased 9v op-amp) in turn controls whether or not current flow across transistor, in theory should cause rc transmitter transmit 'forward' signal.

however, there couple bugs in circuit.  first, flip-flop not transition between states each time receives pulse.  rather, acting normally-closed switch, transitioning open (turning off led indicator) upon incident light, , closed when light removed.  in other words, doesn't seem latching properly.

the flip-flop (cd4013) wired follows:
1: q led / transistor base
2: q bar data 1 (5)
3: clock 1 comparator output
4: reset 1 set (6) vss (7) ground
14: vdd red (9v)

the second issue lies transistor controlling transmitter.  can't seem controlled directly flip-flop, car runs when led comes on , stops when goes off.  currently, transistor either allows transmitted run in either toggle state or in neither toggle state (depending on how wire it).

the transistor portion of circuit shown base coming in @ 0/9v op-amp, +3v (two aas enclosed in transmitter) feeding collector, , emitter connecting 1k ohm resistor 0v end of transmitter.


here're couple images of circuit. first shows half of circuit master power switch led indicating flip-flop output.  green lead leaving @ top of image same 1 in second image.






and here's schematic of i'm trying do.  now, i'm mechanical engineer, theory might bit off -- correct me if i'm wrong, okay? :)



if guys @ all, appreciated.

Thread: PKI Client 5.00 install (for eToken Pro)

-
my company uses aladdin etoken pro authentication on vpn connections. etoken requires pki client application on client machine before os recognize it. app , token work fine on xp, use ubuntu on laptop. aladdin has offered linux version of client, rpm. convinced our internal guys rpms, , i've been trying work couple days. begin with, hp pavilion dv4-1435dx laptop running jaunty 64-bit. - started out converting .rpm .deb using alien: code: sudo alien -d pkiclient-5.00.28-0.x86_64.rpm - worked fine , got nice little .deb - next, ran .deb install client: code: sudo dpkg -i pkiclient_5.00.28-1_amd64.deb - , executed without errors/issues. pdf rpm said there should launcher @ applications > etoken > start etoken pki client, didn't exist. figured might because installed deb instead of rpm. bounced box, still wasn't there. no big deal... - install network manager can configure vpn connection use token: code: sudo aptit...

ATmega2560-Arduino Pin Mapping

hi community, in last days working on project using arduino mega 2560. on planning pin using found bugs in atmega2560-arduino pin mapping . if right there labels (such pwm) in 'mapped pin name' @ wrong row ( mixed pin numbers right one...) in attachment openoffice calc , pdf file corrected table. ( hope ;-) ) i post here tab separated table : code: [select] arduino mega 2560 pin mapping table atmega 2560 pin out arduino mega function nr name function function function mapped pin name function function datasheet 1 pg5 oc0b digital pin 04 pwm 2 pe0 rxd0 pcint8 digital pin 00 rx0 (usart0 receive pin, programming data input or pin change interrupt 8) 3 pe1 txd0 digital pin 01 tx0 (usart0 transmit pin or programming data output) 4 pe2 xck0 ain0 (usart0 external clock  input/output) 5 pe3 oc3a ain1 digital pin 05 pwm 6 pe4 ...

Crossfader Arduino Tutorial

-
hello i'm super newb please don't bash me much. i'm using led's , i've connected them correctly (finally) , wondering why program here ( http://www.arduino.cc/en/tutorial/colorcrossfader ) doesn't work? say's haven't declared crossfade. read directions on top , said crossfade needs used list order of colors. isn't declared in main part (void loop() )? or need declared before? nevermind void on bottom , needed before voidloop. lol anyways playing rgb led's wondering if has specific way of making them fade in , out different colors? (brightness , color mixing) code: [select] /* * code cross-fading 3 leds, red, green , blue (rgb) * create fades, need 2 things: *  1. describe colors want displayed *  2. list order want them fade in * * describing color: * color array of 3 percentages, 0-100, *  controlling red, green , blue leds * * red red led @ full, blue , green off *   int red = { 100, 0, 0 } * dim white 3 l...
