Need to code in Arduino, Buttons for motor movement. Up and down Press and hold button UP, motor goes up. Press and hold button DOWN, motor goes down As soon you release the button, motor stops. Need diagram, wiring and code DM542 steppe driver
Looking for a programmer that can create a program that will set the temperature of a device. The inputs are simple which is just up and down. I would like to have the ability to set the number of clicks. Initial idea on how the program works. 1) connect the hardware/device. 2) program will detect device. 3) program will input commands, up or down by the set number of clicks. 4) disconnect device. 5) Repeat steps 1-4 and the program will automatically start. Currently using a simple board. Pics attached.
I want an arduin esp32 code where it connects with wifi and sends data over mqtt. It will check the internet connecton, wifi connection and of any failure it would try to re-establish itself. We should not need to reboot the device from outside, it should get back online whenever the problem is solved. The machine may restart after a long time when it is needed ,but remember on any failure it should not keep rebooting.
You must live in the Western Balkans, Eastern Europe, Latin America, or the Caucasus. I am seeking either a high school student or a university student to help me build an Internet of things (IoT) device using MicroPython on the ESP32. (ESP32 is a microcontroller just as Arduino is a microcontroller). Why don't you need any experience? I would rather work with someone who is inexperienced yet very intelligent, rather than someone who is experienced yet not very intelligent. I will ask you a question that you must answer correctly, to prove to me that you are very intelligent. You must be able to work for five days each week for one hour per day. You may choose the five days which are convenient for you. You may work at any hour of the day (or night) that you would like.
HART pressure transmitters for configuration via a distributed control system (DCS) or HART communicator. HART pressure transmitters are compatible with the Highway Addressable Remote Transducer (HART) communication protocol which is the most popular standard used with smart field devices by the process control industry. HART functionality enables the transfer of pressure transmitter data via an AC digital signal which uses the 4-20mA analogue output signal as a carrier, thus eliminating the need for extra wires and connectors.
want to have pcb designed with parts available online to purchase currently. Circuit is available please see attached doc. The pedal element I already designed with 4 nos Strain guages. This circuit will give output to the strain guage bridge circuit and gets output in volts which will be applified by circuit and available for data recording. Rest information about circuit and functioning is available in attachement.
Design a low pass filter which I will tell you more precisely. The priority of the project is given to those who have the accuracy of work and high mastery of electronics and receive lower fees. (Altium Designer) Lower cost is preferred. Layout is required.

The PCB thermostat needs to run on 220/230V 50/60 hertz, it needs to have two NTC probes one for measuring water temperature and one for safety (excess water temperature shutdown), rotary, measure from +/-1 0-40 degrees Celsius, it needs to have built in contact suppressor.
I would need a quadcopter drone put together having motors, escs, battery, and so on without a frame and sent to me. Everything would already be connected together and ready to go ,without the need for calibration, using a remote control at the flip of a switch. The motors would need to be high torque and be as flat or least in height as possible. They would need to have the metal shaft already attached and preferably a threaded shaft. The bottom of the motor would preferably be flat too.
i am having a relay which communicates with this protocol IEC 61850
The Controller is PIC16F628A, more details will be shared in private chat.

Design pcb to house an esp32 module and associated electronics to make distance measurements from 10mm to 140mm. Accuracy within +/-10mm. The ultrasonic sensor needs to be mounted external to pcb via a connector. Do not want ultrasonic modules on pcb, u must design that circuit yourself. The esp32 will be going into deepsleep, so u must shutdown any current that will drain the battery. Pcb must accept battery holder. Deliver the following: pcb, schematic and libraries (kikad or eagle) Manuf gerbers Excelfile with bom (digiket, mouser or RS links)

I have a pinball machine with a suspected faulty PCM1755DBQ ship. I have the replacement chip but need it replacing on the MOU board. It’s a surface solder. This is a very small surface mount component that measures approximately 5 x 6 mm (including the chip legs).
Hi, I am looking for somebody who is experienced with the microchip VSC7514 to review electronic design and troubleshoot. We need somebody who is experienced with ethernet protocole. We currently have many items working but there is an issue as when the PC sends some frames to the VSC, nothing is answered. Thanks
I'm working on IoT project. I'm not very technical. I need help to write a python code to allow raspberry pi to automatically connect two Bluetooth devices to specific serial ports rfcomm0 and rfcomm1. and then I want the python script to automatically start on reboot. would require Video call to show everything in details. I might not be very clear about this so please ask me any questions.
Looking for Electrical engineer / Ph.D for signal preprocessing , classification (deeplearning)
Hi, I want to develop 10Msps, 1MHz arbitrary waveform generator. The device should have a PCIe interface to connect to Raspberry CM4's PCIe bus. The following components must be used. CH368, STM32F4 or G4. 10Msps DAC. Deliverable: * Hardware design (EasyEDA, KiCAD, or Altium) * Linux Driver * Demo Python CLI application Timeframe: Until before Dec starts
I have an ESP32 chip with the code attached. The problem is that it works perfectly when pairing it the first time, but when I restart the chromecast v3 or it unpairs or it also happens that it unpairs the remote control from the chromecast having to factory reset it.
We need an HVAC engineer to read the schematics and explain all the details in the schematic
Need to know Mplab Programming for PIC16F628A. Compiler is CC5 x compiler. Details will be send by chat.
Hi I need a custom antenna Bluetooth (2.4 Ghz), I have a design. The antenna has connector IPX-V1 + Wire + PCB (with ceramic antenna) I have a design of the PCB, and I choose the ceramic antenna, I need to somebody can tunning with 50 Ohm and SWR < 2.0 I can send the compent, to do the job. Thanks. Ricardo
