Intelligent temperature monitoring and control system using AVR microcontroller

AVR ATmega Projects, Temperature Measurement Projects / Ibrar Ayyub

Controlling temperature has been a prime objective in various applications including refrigerators, air conditioners, air coolers, heaters, industrial temperature conditioning and so on. Temperature controllers vary in their complexities and algorithms. Some of these use simple control techniques like simple on-off control while others use complex Proportional Integral Derivative (PID) or fuzzy logic algorithms. In […]

Wireless Accelerometer Controlled rgb-LED’s using atmega168 microcontroller

AVR ATmega Projects, Internet - Ethernet - LAN Projects / Ibrar Ayyub

MEMS (Micro-Electro-Mechanical Systems) Accelerometers are in widespread use as tilt-sensors in mobile phones and cameras. Simple accelerometers are available both as ic-chip’s and cheap development pcb-boards. Wireless chips are also affordable and available in assembled circuits, with matched antenna-network and decoupling-caps onboard. Hook both wireless board and accelerometer up to a microcontroller via serial interface
