-<p>Standard setup. How Arduino Uno boards are wired.</p>
-
-<p>Connections: Pin 1 → 5V via 10kΩ resistor. Pins 9/10 → 16MHz crystal via 22pF
-capacitors to ground. Pins 7/20/21 → 5V supply. Pins 8/22 → ground. Add 0.1μF
-decoupling caps between pins 7/20/21 and ground.</p>
-
-<p>Sample Makefile: <a href="Makefile">Makefile</a></p>
-
-<h2 id="33v-8mhz">3.3V-8MHz</h2>
-
-<p>Electrical connections identical to 5V circuit. Replace 5V with 3.3V supply,
-16MHz crystal with 8MHz.</p>
-
-<p>Problem: ATmega328P ships configured for 5V. Must modify fuses (BOD level,
-etc.) and replace bootloader. Standard Arduino bootloader expects 16MHz—needs
-8MHz version.</p>
-
-<p>Solution: Use Arduino Uno as ISP. Upload ‘ArduinoISP’ sketch from Arduino IDE.
-Connect SPI pins (ATmega328P ↔ Uno), Uno’s SS pin → ATmega328P RESET pin. Power
-ATmega328P from Uno’s 5V pin during programming.</p>
-
-<p>Arduino IDE: Select ‘ATmega328P (3.3V, 8MHz)’ processor, ‘Arduino as ISP’
-programmer. Burn bootloader via tools menu.</p>
-
-<p>Sample Makefile (8MHz): <a href="3v3.Makefile">Makefile.3v3</a></p>

-<h2 id="remarks">Remarks</h2>
-
-<p>Don’t connect AREF (pin 21) to V<sub>cc</sub> if using ADC with internal 1.1V
-or AV<sub>cc</sub> reference. See datasheet section 23.5.2.</p>
