Developing a Strobe Light Source Using ESP32 for Kinematics Experiments

Developing a Strobe Light Source Using ESP32 for Kinematics Experiments

Recently, the microcontroller enthusiast has been researching how to use light-emitting diodes (LEDs) to replace the dot timing method to optimize kinematics experiments. Initially, self-flashing LEDs were used, but due to the equal duration of the flashing and dimming, noticeable motion blur was produced. To avoid motion blur, the enthusiast used the ESP32 development board … Read more
