    PCB Compliance Test 6 ditë left
    VERIFIKUAR

    I require a PCB compliance test. test will determine if PCB is capable of passing EMC/EMI compliance tests and all relevant tests relating to CE mark and FCC standards. 1: 2 x PCBs need to be tested. 1 is extremely simple with just 6 switches on it. the other is more complex. 2: Timeframe would be as soon as possible. these boards are fairly simple so shouldn't be too difficult.

    I am creating a project which will involve two NEMA 17 motors driven by two A4988 Drivers and using the ESP8266 module. The motors are used for horizontal and vertical movements. I want to create a list of 50 processes where each process will specify motor speed and direction for both motors. For eg: Process 1 may involve moving motor 1 for a few seconds, and the motor 2 and then again motor 1 in another direction and then motor 2 and so on. I am looking for someone who has time and is excited to be involved in this kind of a project. Some experience in Arduino is essential. I want to finish off this week.

    I have a simple circuit that is a battery operated rgb color switcher that runs on a PIC10F202; When the button is pressed, the single RGB LED changes to the next color in the sequence. When the battery is installed, the unit is on, and when the battery is removed the unit is off. What I need is to have the code modified so that the uController behaves in the following manner: 1 Unit is off with battery installed 2 Button is pressed once 3 Unit turns on with last selected color illuminated 4 Successive button presses will cycle to the next color in the sequence (R->G->B->Y-C->M for example) 5 Unit will stay illuminated in the current selected color until, 6 Long press (2 seconds) will shut the unit off and save the last selected color in memory 7 Operation repeats as above ...
