Precision Cooker: A Temperature Controlled Cooker Using Atmega1284

Leave a Comment / Using Atmega / By Tech Master

Precise time and temperature control are critical when cooking. Slight deviations in either temperature or cooking time can ruin delicate ingredients. Despite this fact, most modern day stovetops provide no data regarding their current temperatures and do not have built in timers. The stovetops that do provide these functionalities are often expensive and require specialized …

Self-powered solar data logger using ATmega32

Leave a Comment / Using Atmega / By Tech Master

Introduction: My project is a self-powered solar data logger. Put out in the sunlight, it will measure the light level and log this to memory to be later downloaded to a computer. The system is powered by a small solar panel and battery. Summary: The solar logger I built uses a photodiode to measure the …

Frequency Visualizer Using Atmega

Leave a Comment / LED Projects / By Tech Master

Introduction This project visually displays the frequency content of an audio signal using an 8X3 grid of LEDs. A microphone and amplifier collect analog audio input which is sampled digitized using the MCU’s analog-digital converter. The samples are buffered and and a 32 point discrete cosine transform is performed in real time to obtain 32 …
