This battery-powered water level monitoring uses PIC12F683 as main processor. The project works in the sleep mode to reduce power consumption. Each 2 second, the watchdog timer will wake-up the MCU and then check the sensor probes condition. If the sensor probes submersed in the water it will generate sound Beep and then go to sleep mode again. The sensor probes made from solid copper wires. Project firmware.

The goal of this project was to build and implement an inverted pendulum balancer based on microcontroller, in the vertical two dimensional plane, using Proportional-Integral-Derivative (PID) feedback control.The project uses radio controlled car which has been modified by adding a plexiglass platform and an inverted pendulum with free rotating pivot. The main components of the balancer are Atmel ATMega32 microcontroller as computational hardware, US digital optical shaft encoder as input angle sensor, and National Semiconductor LMD18200 H-Bridge as output motor driver. All these components are brought together onto a single ...

Recently, Jaime Andres Arteaga designed a simple C program to use a SRF05 ultrasonic sensor, low cost ultrasonic rangefinder up to 5 meters, with AVR ATmega32. The microcontroller sends a pulse trigger (10 us minimum) and then, the sensor produces a pulse that is proportional to the distance.In this project, the SRF05 is connected in MODE 1. This mode uses separate trigger and echo pins, and is the simplest mode to use. To use this mode, just leave the mode pin unconnected - the SRF05 has an internal pull up ...

The project goal is to build a battery powered azimuth and elevation antenna positioner, using inexpensive hobby servo motors and gearboxes, for portable operation. This project allows portable satellite tracking is done automatically (operate hands-free).The elevation rotator uses a 'Standard Servo Power Gearbox' and a HiTech HS-7955TG servo motor. While the azimuth rotator uses a 'HS-805/815BB Servo Power Gearbox' and a HS-805BB servo motor.The servo motors are controlled by a Parallax development board holding a BS-2 Basic Stamp. In addition, a Parallax ‘ServoPAL’ is used to refresh the servos so ...
