Introduction AVR ADC using TLC549 demonstrates how analog signals from sensors can be converted and processed by a microcontroller. Analog signals from sensors cannot be processed directly by most microcontrollers because they operate using digital logic. To bridge this gap, Analog-to-Digital Converters (ADC) are used in many microcontroller projects and embedded systems. This project demonstrates […]

Introduction Analog signals are everywhere in real-world electronics, but microcontrollers process digital data. In this microcontroller project, an ADC0808 analog-to-digital converter is used with the ATmega16 microcontroller to convert an analog voltage into an 8-bit digital value. The converted digital value is then displayed through LEDs, making it easy to visualize the analog input level. […]

Introduction This microcontroller project shows how to build a dual digital thermometer using an ATmega8515 and two DS18B20 temperature sensors in Proteus simulation. The system reads temperature from both sensors, displays the live values on a 16×2 LCD, and also keeps track of minimum and maximum readings. It is a practical example of embedded systems […]

Introduction This microcontroller project demonstrates how an ATmega8515 communicates with external memory inside a Proteus simulation environment. The design focuses on memory access cycles, showing how the AVR handles external address and data lines when connected to SRAM. It is a useful example for anyone learning embedded systems, memory-mapped interfacing, and practical electronics. Instead of […]
