Car Lock
This is a project made in MikroC in C, for the PIC16F84A, but it can be used with virtually any MCU with a little bit of tweaking. The circuit schematics I used could be uploaded and published if needed.
This is a project for a central lock system of a car. It takes inputs from both RB1 and RB2 for a predefined duration, and outputs with a predefined duration to RB5 and RB6 to lock or unlock the car.
Truth Table
| Inputs | Outputs | ||
| RB1 | RB2 | RB5 | RB6 |
| 0 | 1 | 0 | 0 |
| 1 | 1 | 1 | 0 |
| 0 | 1 | 0 | 0 |
| 0 | 0 | 0 | 1 |
In this case, RB1 is pulled down and RB2 is pulled up. This was done since the signal is coming from a single wire.
- When RB1 is closed the system is locked.
- When RB2 is grounded the system is unlocked.
Feedback / Support
This is primarily a finished project. And is not something I am prioritizing. But I am open to changing/fixing anything with your help.
