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
Experimental Scene and Circuit Connection Recently, I found online that a teacher published a paper in a journal, using the voltammetry method to measure the resistance of a photoresistor while measuring light intensity with a light sensor, then plotting the relationship curve of photoresistor resistance and light intensity in a spreadsheet. The steps are cumbersome … Read more
Enable the multi-core functionality of the ESP32 to execute tasks in parallel while setting the chip’s clock frequency and the FreeRTOS real-time system. The effect achieved in this article is shown in the GIF, where two displays execute in parallel, each using one of the ESP32’s two cores. The display of the two screens, if … Read more
