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 ...
- PCB Redesign; - Change from ESP8266-01 to ESP82266-12F; - Add 2 new sensors (temperature, humidity and gas); I accept suggestion for sensors (sensor Mq-2 and Dht11) - Update BOM componets with end of life; - Work on tentative the remain within PCB same size. - Ultimate goal is to make the PCB with the lowest possible cost of production and manufacture 10 samples for test; notice: currently i am using MCU Mega 2560 and isn't possible deploy FOTA (firmware over the air) with ESP8266-01 (Serial3). So, if identified any concerns please, let me know before start
PCB design, manufacture and firmware programming for a heating controller. It will involve multiple inputs and outputs, both digital and analogue, NTC,0-10v, pulse, CT, on-off, power supply, separate high quality touch screen controller, 8 gig SD storage, Modbus master, Lora, Zigbee (connection to Sonoff sensors), Wi-Fi and LAN. It must connect to a website for analysis of data and the ability to upload data and download instructions and update the firmware through the internet. The project will also include the development of the firmware, website apps ect. I do have a precious version written in C as an example. A full description of the firmware will be supplied after a NDA is signed.

We are in need on an embedded (PCB) relay board. Looking for a ready and proven solution with any microcontroller(STM32/PIC/Renesas/TI/NXP etc.) with Ethernet interface. The job left would be to add the Relay section and that should be done as part of the project.
I need experts to have good experience in power line communication to build firefighter telephone system by using addressable node
This is the glymse of the project: This project uses multi-frequency and multi-constellation Global Navigation Satellite System (GNSS) receivers to receive and converting from the received International Atomic Time (TAI) to Coordinated Universal Time (UTC). Once received it syncs the onboard Temperature Compensated Crystal Oscillator (TCXO) or Oven-Controlled Crystal Oscillator (OCXO). Design Schematics, PCB and Firmware Development. Details of the Project will be discussed after evaluvation
The project is to read frequency from a magnetic sensor and display the reading on a stepper motor and oled display and design the PCB board.
Hi, We have designed a PCB around the STM32F401 + SIM868E. This PCB has been designed in Altium and has some connection issues which needs to be resolved. So in short the PCB design needs to be validated and potentially reworked. Please contact for more information.
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...
Hi, We need help from electronics hardware and firmware designers who have worked on DSPs before because device on which we are working is based on signal processing. Further details will be shared with selected freelancers only. Thanks.
I want basic and pcb design which can be used for all devices. containing essential components like microcontroller oscillator power module etc.
We are working on a somewhat stealth electric car charging company and need assistance from a EE experienced in PCB design, high voltage, high amperage, and more.

I have 2 PLC,s communicating with wireless Modbus RS 485. Slave requires minimal code measuring up to 30 PPS, battery voltage a latching relay and possible count reset command. My intention is to eliminate the Slave PLC. I'm looking for someone who can help me with: (1) I have programs written into 2 PLC,s 1 Master and 1 Slave they are linked via RS 485. (2) They communicate through 2 RS485 wireless transceiver,s The Slave PLC has got a very simple program in it . My task is to move the program in the Slave PLC into a microcontroller. I'm presently using an Arduino UNO for the task I've got the majority of the coding done. In closing, I need someone who has SPECIFIC knowledge in IDEC PLC,s and Arduino microcontrollers.
