An Exercise in Futility: Edge detection on a ST7920 128×64 LCD display
Ever since doing the successful real-time edge detection experiment using the GC9A01 display, I couldn’t help but wonder what it would be like on the […]
Real Time Edge Detection using ESP32-CAM
This project builds on the experience gained during the previous motion tracking ESP32-CAM project, and is simply just a proof-of-concept to see if the ESP32 […]
Comparing the Garmin LiDAR-Lite V3HP with the Benewake TF-Luna LiDAR sensor.
I’ve previously tested beam divergence of the Benewake TF-Luna as part of the VL6180X distance sensor write-up, which also includes results from the Sharp IR […]
Testing the PWM and Braking functions of the DRV8871 driver and 775 DC motor with an AS5600 sensor.
Curiosity is a strong driving force; especially, when there is a note on the datasheet regarding braking and PWM control. You can see the note […]
