Lap Counter with STM32 and two 7-Segment Display Modules
In this video, I show how to build and program a device that increments a counter each time a vibration switch is triggered. To complete this project, it is helpful, but not necessary, to have some basic understanding of electronics. This video is intended for novice hobbyists, hackers, DIYers, makers, etc.
In this video, I use a few different Arduino IDE sketches to program the STM32. The Arduino IDE sketches are available in my Google Drive:

Items need for this project:
STM32F103C8T6 Development Board
5611BH Common Anode 7-segment display (2 ea.)
USB to TTL Serial Converter (FT232RL)
Vibration Sensor, Wingoneer SW-420 NC
Buzzer CMI-9653S-SMT-TR
SPDT Slide switch 09.03201.02 (2 ea)
Transistor BC547B (3 ea)
Keystone Electronics Battery holder number 2468
Pelican Case 1010
Breadboard, resistors, LEDs, wire, solder, etc.
If you want to design a printed circuit board (PCB), like the one I used in the video, I suggest using ExpressPCB. You can use my file (LapCounter2.pcb) to order a board with the exact same layout, or you can design your own layout using the ExpressPCB software. You can find my file (LapCounter2.pcb) in my Google Drive.
