    This is a project for using an Arduino module and interfacing to Wi-Fi, BLE and ZigBee. The designer must chose a suitable radio module with performance at a good price. The designer must include all schematics, net list, bill of material. Upon receipt, our company will send the PCB order to the automated system of JLCPCB and if the order is accepted as being in a state to produce, then we will pay the freelancer. Small minor adjustments to component placement may be required after or review. This is part of the project as it is well known that items may arise that need adjustment. Consideration may also be given to the Freelancer on other projects to include software interface to the radio devices (Wi-Fi, BLE, and Zigbee) R.F. experience would be an advantage to the Freelancer.

    Im trying to design a handheld device that would help me diagnose failed components. A quadrature encoder and a SSI linear positioning transducer. I have most of the electrical design done. I would need help with the firmware. Basically. I would like to read the signal from the encoder and The transducer and display it on a screen (preferably an oled screen). And also replicate those signals. The idea behind the device is I want to hook up on the ( encoder let’s say) spin it by hand and see if it still works ( see if all channels are working ) then if it’s working, unhook the encoder and hook on the cable and create an encoder signal to send to the PLC, to see if the wiring is good

    I have attached all the parts I have right now, if more are needed i can buy. The basic concept is to have it mimic a heart beat, the first motor will pulse the the second motor will follow it. All the while the RGB lights will be changing colours smoothly while also pulsing. I have a battery and connecter so I would like for the device to be able to charge it and also run on its own. I am not sure if the parts will run smoothly together so I would like someone experienced and willing to do revisions and spend time on exactly what I need. I have added links to all the parts I have. Please do not waste your time thinking it will be a simple project or try bidding higher or wasting my time. Thank you. The project is 60 dollars..
