Atmel tinyAVR microcontrollers are optimized for applications that require performance, power efficiency and ease of use in a small package. All tinyAVR devices are based on the same architecture with other AVR devices. The integrated ADC, DAC, EEPROM memory and brown-out detector let you build applications without adding external components. The tinyAVR also offers Flash Memory for

I recently had the need to carefully measure a voltage with a microcontroller which lacks an analog-to-digital converter (ADC), and I hacked together a quick and dirty method to do just this using a comparator, two transistors, and a few passives. The purpose of this project is to make a crystal oven controller at absolute minimal
