    This project involves navigating a vehicle through a minefield by using audio beacons of fixed frequencies located throughout the field. The vehicle will start at a fixed location in the field. The mission is to locate the “next” audio beacon and steer the vehicle toward that beacon while monitoring for the next beacon. The vehicle should continue to search each consecutive beacon until the final beacon is located, indicating the vehicle has exited the minefield. During the journey, the vehicle may not collide with any of the beacons and must steer clear. Vehicle Details: The vehicle consists of an aluminum chassis with three wheels (one front center wheel, two rear wheels). Each rear wheel has a dedicated DC motor used to motivate each wheel independently. Both DC motors are connected to a PWM motor driver unit that controls the RPM of each motor independently based on a 2 PWM signals. The details of the PWM motor driver are included in the appendix. Microcontroller: Teensy 3.2 Real Time processor: This microcontroller will interface the PWM motor drivers on the vehicle and the microphone sensor (and any other sensor you may include). Plan to power the vehicle separately from the microcontroller. A four bank AA battery pack is sufficient for the vehicle, while a separate power source may be used for the controller. Do not power the motors through the microcontroller; it is not capable of providing sufficient current. Battery packs may be purchased from [url removed, login to view] or adafruit.com. Sensor Details: The microphone/amplifier assembly is described below. [url removed, login to view] Beacon Information: Each beacon is a piezo buzzer tuned to a particular frequency. Details of the buzzer are below: [url removed, login to view] Rules: 1. You may use preassembled libraries for PWM signal generation and audio processing. 2. One group will be tested at a time. The vehicle will be placed at the starting point, and the beacons will be turned on. There should be a “Go” button on the vehicle to start the journey to the finish line as well as a visual indication (LED) that the journey has ended

    I have a GPS tracer device Coban TK103B for tracking vehicle. The device is controllable via SMS and GPRS. I would like to rewrite the firmware to receive SMS message from GPS tracker in different format. For example: Original Current Location SMS message: picture (1) Expected Current Location SMS message: picture (2) The project consist essentially of edit SMS message received from GPS tracker. I need source code and instructions on how to flash the device.

    I want the neopixels to go rainbow in colour when the cushion is stood on or Moves. Motion sensed not pressure switch. When the cushion is not active (Motion sensed) I want the neopixel ws2812b leds to be at 30% brightness Rainbow pattern. Soon as cushion moves with the mpu6050 the lights are 100% bright Rainbow. Also would like the ability to switch the cushions (4 in total) red and green via a Bluetooth app on android phone.3 position switches on;off;on (so 8 buttons in four groups labelled 1 2 3 H). also a button on android app called PLAY that makes the cushions go blue for 20 seconds. How much to code? using a minipro with 15 Neopixels per cushion with a MPU6050 to sense the motion via the IMU. . Range required approx 15 to 20 meters. between cushions. hc05 bluetooth module or better (what do you recommend.) 15 x ws2812B neopixel leds in a string. Minipro atmega328 with 32k of flash for sketch 2 k being bootloader. 2 or 3 18650 batteries for powering for up to 4 or 5 hours. will need a sketch for each cushion or a sketch with the ability to change so i can do the task above i want it to do.

    Write arduino code A0 detective voltage from input in the above circuit A1 detective voltage from output in the above circuit A2 detective voltage from battery 10 of arduino give pwm to Q1 4 of arduino give 5v to relay to control it on or off On the top is a boost converter, the input will fluctuate from 0 to 6V. Now i set 5V. Arduino control the pwm so that the voltmeter A( in picture) should show 12V. The principle is to control the duty cycle A2 detective voltage from battery , if the voltage higher than 13V or lower than 10V, arduoino will close the battery to charge led . The detail way:1 the pwm from arduino/tlp250 to control the output voltage in the top circuit is o voltage. 2: arduino give 5 voltage to relay(5V voltage it will close) , the relay is off. A0, A1, A2, duty cycle value should show on virtual terminal The code should make the simulation can run correctly ,pls remember or , i wont pay ..--------------------------------------------- I dont ask u to do next, if can do the former mission ,i will pay more to do next Brightness and pwm-led is to control the brightness of led
