Hello everyone !!!
i have this 2 RC car toys in the junk ... so i have the idea to modify them into one car that has much power and speed .... So i reassemble them into one frame and i got this one :
*******************
-------------------------
*******************
This new Toy contain 2 DC motors in the Rear and One Steering Dc Motors in the front ...
the old circuits contain just 2 H-bridge for 2 Dc motors, when i test it one H-Bridge is Burned out cause i connect it to 2 Rear Dc Motors, So i figured out that i have to add a new H-Bridge to my second rear Dc Motor ... The demodulator is a chinese clone of the RX-2 Chip ... When i tested it's output i found that it output pulses (when i trigger forward it generate a positive pulse ... and when i release the forward trigger, it generate a negative pulse ) and with this pulses it make the DC Motors Runs .... So i searched in the Internet and i figured out that it could be a latching circuit after this pulses ... However when i retrace the Circuit i did not found any LAtching Circuit ... So this is my problem and i want someone to tell me how this thing "Chinese RX-2 Chip" control the DC motors with Pulses ?????
*******************

*******************
You will Found in the attachement the circuit schematic of the H-Bridge
*******************
Here is a video about the result of the oscilloscope in the output of the left and right ouptut pin signal

*******************
So i want to know how this thing make a dc motor turn on ??
How could i make another H-Bridge that trigger on with this kind of pulse for my Third DC Motor ??
Thx ??
