Summary of CAR SPEED ALARM CIRCUIT DISPLAY INDICATOR PIC16F84A
This article describes a car speed alarm circuit using the PIC16F84A microcontroller. The project features a front panel with a 3-digit LED display, an indicator LED, and three pushbutton switches. Users can set an alarm speed between 0 and 155 km/h in 5 km increments. When the vehicle exceeds this limit, the LED lights up, and an internal piezo alarm sounds every 10 seconds. Source code, schematics, and PCB files are available for download.
Parts used in the Car Speed Alarm Circuit:
- PIC16F84A microcontroller
- 3-digit LED display
- LED indicator
- Three pushbutton switches
- Internal piezo alarm

It’s also just as easy to drive as before. As shown, the front panel carries a 3-digit LED display, a LED indicator and three pushbutton switches. Two of these pushbuttons let you set the alarm speed in 5km increments between 0km/h and 155km/h (one switch increases the speed; the other reduces it). As soon as you exceed the preset speed, the indicator LED lights and an internal piezo alarm briefly sounds at 10-second intervals to provide a warning
