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
Recently, the microcontroller enthusiast has been using Phyphox and ESP32 Bluetooth to redraw the I-V characteristics of a light bulb, continuously changing the experimental parameters in hopes of finding the optimal settings. In one experiment, the enthusiast set the sampling frequency of the ESP32 to 100Hz and slowly adjusted the voltage across the light bulb … Read more
