My setup is an ESP32 wired to a 2.8-inch ILI9341 LCD (I may swap to the 3.2-inch variant; both share the same driver and pinout). All images sit on an SD card; more than fifty of them may be shown . I need a complete MicroPython solution that pulls each JPG straight from the card and pushes it to the display with no intermediate PC-side conversion. Core needs • Initialize the ILI9341 (ST7789) over SPI, handle 320×240 resolution, and work with both display sizes out of the box. • Mount the SD card, scan a folder, and stream-decode each JPG so the ESP32’s RAM footprint stays within limits. • Cycle through every file in the list inside an endless loop; I’ll decide the delay between frames in a simple variable (e.g., DELAY_MS). • Show each image f...

I need a clean, well-commented Arduino sketch for the Pololu 3pi that lets the robot visit six preset locations, interact with the magnet at each spot, and return to its starting line in under four minutes. The only sensing method available is a magnetic sensor array, so all point detection and interaction logic must rely on that hardware. Two run modes have to coexist in the same program and be switchable through a simple flag, jumper, or serial command: • Intermediate – the robot must physically touch the magnet before leaving the point. • Difficult – the robot should recognise the magnetic field, stop just short of contact, and then continue. Between locations, I expect a mix of straight dashes and graceful curves; please handle path planning so the 3pi&r...
