该电路将允许用户使用手机蓝牙锁定他的汽车点火开关，这意味着只能通过用户的手机蓝牙的特定代码锁定点火。
Overview
在我之前的一篇文章中，我已经解释了how to hack a Bluetooth headset并将其用于通过蓝牙的任何所需的切换应用程序，在这里我们将相同的概念应用于提议汽车点火锁circuit using Bluetooth.In the project the cellphone becomes the Transmitter circuit, and the Bluetooth headset is used as the receiver.
如果您不希望将蓝牙耳机修改为接收器电路，则可以采购现成Bluetooth receiver unit也是如此
这个想法实际上非常简单，可以通过参考以下给定电路来理解：
这个怎么运作
我们可以看到the circuit is configured around a specialized锁相环路IC LM567which is designed to generate a low logic whenever it detects a frequency at its pin#3 that may be matching exactly to the IC's internal oscillator frequency set by R1/C1.
For example, in the above diagram the internal oscillator frequency is set at 100kHz by appropriately selecting the values of the R1/C1 timing components, therefore it implies that the IC will produce a low logic whenever it detects a 100kHz across its pin#3 and ground. As long as this situation is not satisfied, pin#8 can be expected to be at a logic high level.
The C4 end and the negative wire of the circuit is supposed to be joined with the Bluetooth headset or any selected similar Bluetooth audio receiver gadget. This could be also easily done through an opto coupler for allowing a complete isolation between the two stages.
This takes care of the Bluetooth receiver stage circuit, now lets' move on and learn how your cellphone needs to be set up as the Bluetooth transmitter unit.
为此，您需要在Android手机中下载频率信号发生器应用程序，或者如果手机不是Android手机，则可以记录所选频率的5秒剪辑，例如，以上显示的100kHz频率夹设计。
How to Test the Circuit
完成此操作后，是时候通过以下步骤测试提出的蓝牙点火锁定电路了：
1）将手机和蓝牙接收器配对与蓝牙配对。
2）从手机切换100kHz频率，然后将其发送到接收器小工具。
3) Wait for a few seconds, and ...."click".... you will find the relay operating, and unlocking or locking the car ignition, depending upon the initial situation of the relay.
操作触发器中继的略有延迟是由14号PIN＃14的100K/1000UF组件启动的，这对于使系统的万无一失所至关重要，因此入侵者可能不会尝试通过随机发送锁定来打破锁接收器小工具的蓝牙频率。
This delay must be confirmed with some trial and error, the indicated values of 100k and 1000uF is arbitrarily chosen, and may not be accurate.
TheIC 4017 is rigged as a flip flop circuit which toggles the relay ON/OFF alternately in response to the LM567 signal.
可以看到继电器与点火开关集成在一起，这意味着只要关闭此继电器，就不能将点火键用于启动车辆，并且只有触发继电器后才可以工作。
如果您对此电路有其他疑问，您可以通过下面的评论询问他们
Sir SWAGATAM,
YOU ARE THE BEST AND BEST TEACHER, FRIEND AND GOOD MAN. GOD BLESS YOU
我的荣幸也很高兴，上帝也祝福你！
先生，美好的一天，我可以找到已经建造的东西并尝试在我的汽车中安装的东西吗？
如果是这样，近似值和多少近似？
sorry MDU, I do not sell readymade kits, I can only advise regarding the circuit
can this be made to work with a specific code so that only your phone can open it
它已经设计为用户手机内部的特定频率集……
哇，先生。
我尊重你。
我将在高风险汽车盗窃国中为我的高风险汽车建造这一点。
@mdu Magubane，Ziya Buya la e mzansi哈哈。
很开心你喜欢！
Awesome. Ever thought of applying these circuits to cut the fuel supply instead of focusing purely on the electric side?
Big fan.
Thanks childs, glad you liked it…
我先生的另一个问题：
我希望能够远程操作我的车窗（就像现代汽车一样）。我有前电窗，但仅此而已。更糟糕的是，要打开前乘客侧窗，我必须俯身并伸展以按下按钮。我想将该按钮更靠近家（大声笑，例如，如果您知道我的意思，可以从我的驾驶员座椅上舒适地操作它）。
Big fan.
嗨，孩子们，可以使用齿轮电动机和限制开关来实现。电动机可以使用DPDT继电器和433MHz遥控接收器配置。
完成此操作后，可以根据需要将负载（窗玻璃机构）向上/向下切换。
Hi Mr Swag. In your discussion you talk about a 100K resistor going into pin 14 but on the diagram it is 10K. Is this a mistake or it is the arbitrary choice of the 100K/1000uF? If so can you please state the range of R to achieve the desired delay.
Also, which relay would you recommend? I’m still starting out at this DIY thing.
嗨，孩子们，是的，这一点并不关键，可以通过反复试验选择所需延迟。
电阻的值可以在10k和1m之间，电容器可以从1UF到100UF
Hi Mr Swagatam. I ordered the parts for this circuit, however I see that I received the CNY17-3 instead of the 4N35 optocoupler. Is there any significan difference between the two optocouplers? Can the CNY17-3 do the job of the 4N35?
谢谢你的帮助。
孩子。
嗨，孩子，两者都会做，但是我在上面的设计中看不到任何光耦合器
否。对于本文第一个链接的“修改后的蓝牙”电路所需的OptoCOPOPLER。
您好先生Swag先生，如果阅读了DataSheet IC LM567，则用最大9V DC提供。在该电路中是供应12V dc。可以安全地用12V DC提供IC LM567吗？
Hello Sarwana, yes LM567 works with a maximum of 9V, I have corrected the diagram accordingly, please check it now
尊敬的先生。
这是穆罕默德（Mohamed），高级工程师。对于RL1，众所周知，当您启动发动机时，高电流值必须通过RL1。因此，RL1的技术规格是什么，最大电流可以通过什么
问候

嗨，穆罕默德，您可以使用30安培汽车类型的继电器，为此，您必须用2N2222晶体管替换BC547晶体管
