Drive relay with AVR microcontroller
To drive a relay, a current greater than 20mA is required, which cannot be supplied by a single microcontroller pin. Therefore, a relay cannot be connected directly to a microcontroller pin. Instead, a simple amplifier circuit consisting of a single...
Acceleration Monitor using ADXL202 and AVR
The schematic indicates that the AccelR8 utilizes only three integrated circuits (ICs). An AVR 8515 microcontroller performs the computational tasks and manages the other circuits. A MAX603 regulates voltage and controls the power-on and power-off functions. The key component enabling...
AVR Robot Board
The Atmel AVR series are very good microcontrollers with quite a rich instruction set, rich enough that lots of folks have good compilers for them so we don’t have to learn their assembler. A very rich compiler available is the...
TV remote controlled computer mouse (an avr VUSB project)
While lying in bed and watching movies on a laptop, the idea arose that having a remote control would simplify the tasks of pausing, playing, fast forwarding, rewinding, adjusting volume, and playing the next track without needing to approach the...
Morse Code Bicycle Safety Blinker
This project utilizes an AVR microcontroller as the first embedded systems project since college. The programming options were C and assembly, with assembly chosen due to familiarity and robust documentation in datasheets. Assembly provides a clear understanding of the operations,...
thermometer dengan avr
The module provides a pre-wired multiplex of a 4-digit common anode LED, which is quite useful. The soldering pad for these signals is shown in the first picture below. A friend provided an AT90S2313 chip, along with a simple homemade...
