By rastering a 365 nm UV spot across a sample and capturing the emitted fluorescence with a BPW34 photodiode, you reconstruct a digital image on the 2.4-inch TFT display. Tune the analog front‑end, calibrate stepper motor microsteps, and map fluorophore distribution at a resolution impossible to achieve with conventional wide‑field optics alone.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eA self-contained fluorescence microscope that scans sample slides in an XY grid, records emission intensity point‑by‑point, and displays a reconstructed image in real time. The Arduino Mega orchestrates two NEMA 17 steppers via A4988 drivers and the CNC Shield, while the LM358 op‑amp chain amplifies the photodiode signal before 16‑bit ADC conversion.
