Change the rc car command code

Add a rc car chanel
In the previous article I discussed about how to change the frequency of rc cars by the method of changing the carrier frequency. This time I will write how to add rc car canal with method change command code.
So the transmitter and receiver frequencies remain as specified by the rc car's rod or the remote control is usually shown 27Mhz, 40Mhz, 49Mhz.
This way I get from seeing and dismantling the original remote of the existing car switch a, b, c his in remote controll and in his car. For the brand I forgot and after all the goods have been damaged and changed hands to the hedgehog hehehehe ...
How to work the switch in the rc car is when the switch on the remote control we slide in A then the switch in the rc car must also position A, otherwise then the car can not be run. Well if we have 3 cars with switch A, B, C means we have three cars with different command code.

Immediately suppose we have 3 cars with a frequency of 27Mhz, we give the car A + remot A, car B + remote control B, car C + remote control C. Open / unloaded car + rremote control A and C, car + remote control B let alone.
Add a rc car canal with code
1. Change the resistance / resistor in the car and remote control A with 100K ohm value.
2. Change the resistance / resistor in the car and remote control C with 330K ohm value.
Now we have 3 pieces of 27mhz rc car with different command code. I once tried to add the code command by replacing one rc car again with a value of 470K ohm resistance and succeeded. So in one carrier frequency there are 4 different channels / command codes.
It's just for the value of 470K ohm resistance has the disadvantage that when the remote control we run, rc car does not directly respond. There is a split-second break of the rc car responding to commands from its remote control.
You can develop your own method above by trying to change the value of resistor / resistor other than I example. Hopefully what I write can be useful. Visit my blog to get more recent articles

Modified car command code remot
In the transmitter (remot) and receiver (car) IC there is a foot osc in and an osc out which is connected to a resistor or a resistor with a default value of 200K ohm there is also a value of 220K ohm.View image.
Changed the rc car command code to a lot
If you see the original circuit resistance value in the switch position A 100K ohm position B 220K ohm, position C 330K ohm. Then how do we apply it in our remote car? I did not make additional switches in each car, but I immediately changed the resistor resistance of the command code.Immediately suppose we have 3 cars with a frequency of 27Mhz, we give the car A + remot A, car B + remote control B, car C + remote control C. Open / unloaded car + rremote control A and C, car + remote control B let alone.
