    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 ...

    Hello everybody, me and my six person team are developing a real-life hardware payment portal which runs with crypto currency payment like IOTA, BTC and ETH. The payment portal has a display introducing the customer. After successfull payment the integrated switch turns on any service, e.g. washing machine (pay for action), car wash (pay for action), car charging device (pay for energy). There are endless use cases. See benefits in the appendix. For this job I would like to get a print ready DIN A4 brochure 2 or 3 folded, both sides illustrated. The hand-over data should be TIF, PDF and native format. After this first project, if both sides of partnership are confident with each other, I would like to continue with designing a proper logo, website and possibly a smartphone application...
