    I looking for a freelancer to modernize my General Motors Delco Radio head unit (Google: Model 16154435 GM Delco) with Raspberry Pi or similar controller so it looks like my original head unit from 1991 but understands Bluetooth, subwoofer, USB and possible Wifi + Spotify etc... I can provide an original Delco Radio head unit for this project to begin with. The classic Radio unit features ========================= - Controls for Radio stations - 8 memory banks - Speakers Fade (rear - front) - Speakers balance (left - right) - Volume control - Tune control. - Single color segment display which brigthness reacts to cars Lightning brightness controls What I am looking for the modernised version ===================================== - Project must use buttons and front face of the origin...

    Arduino BLE Scanner Sketch 6 days left
    VERIFIED

    The Sketch needs to scan for specific BLE devices and then display a signal strength via a coloured 5 led bargraph, play a beep, and show accumulated points for the time spend within the vicinity of a found BLE device. Required deliverable for this project will be a single Arduino Sketch. This project is a follow on to a previously completed Bluetooth BLE Scanner MIT Inventor App (see project brief attached). The APK can be found in the project files on Freelancer. The objective of the MIT Inventor app was to prove that the BLE scanner concept would work. This follow-on project will to be to extend the concept to an Arduino Nano Microcontroller. See attached PDF for full project description

    Hello, I'm interested in building a small controller for my small garden room, that have input, and then based on input data, it deals with output. The following are the main input and output. - Battery level reader - 2 Water Pump for 2 different job work - Water level - small Peristaltic pump - Humidity reader - Temp. Reader. - Open switch (to let fan work and decrease humidity) - Open switch (to let EVAPORATIVE COOLER work) can it be done with Arduino or another microcontroller that work with battery? if yes, then how ,much will this project cost me?

Two processors on two separate PCBs will monitor GPIO pins for digital and analog inputs and comparing those values to alarm set points and annunciating alarm status via LED outputs (about 20; green=good, red=alarm). The two micros will communicate between each other via serial ports (converted to RS485 via single chip convertor). A couple other features such as detecting physical key turn-on and time-out-timers will be required. PCBs are being laid out now. Coding should start right away. Will include Ethernet port and Simple GUI for viewing/clearing alarms.

    We are looking automatic wire cutting and stripping machine which can do this job from 0.1 mm wire ( copper wire) upto 6 mm sq and of different lengths. The machine should not use any hydraulic and pneumatic system for Operation. We would be able to give input to the machine through the push button available and also directly through the computer or data stick in case of bulk requirement ( different cable length). If the machine can itself take different cable ( sq mm) and cut it into desired length as per table or input provided in bulk would be great.

The previous project was completed on the Microchip Ethernet Starter Kit II and is an Ethernet 2 Serial project. There has been a new pcb built with the 675 but with many of the same components as found on the Starter Kit. The new board has some pin changes from the Starter Kit. As much as possible has been kept the same. The new board does have more capabilities than the old Starter Kit. The new capabilities will need to be implemented as a separate project after the basics have been achieved with this project. A document outlining my general communications policy and another document showing the pin changes will be included in this project. Please communicate any difficulties you may have wit...

    This report introduces the wireless sensor interface project of the SEP group project. The objective of the project is to develop a system to collect data from sensors, and to transmit this data wirelessly to a node which passes the data to a PC. Wireless transmission methods have been investigated, and it was decided that a proprietary protocol would be designed. A TDMA based protocol has been designed. Sensor tests have been performed, and the protocol has been designed and detailed in this report. This report also discusses the progress made to date on the project, and proposes a timeline for the completion of the projects

    Main idea. To have multiple buttons around a office/home and when someone presses it a blink/signal will occur on the units like a common signal for an event. To ACK the signal everyone will need to press the button to confirm. This is a MVP concept design and I will add more functionality later. The only HMI will be a button and a LED (maybe RGB) so all info will be via that interface I will do all HW myself and want a fully functional software delivered. Assume the freelancer have this stuff at home to laborate and test the HW setup for a secure and proper debugging.
