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
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.
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.
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
We need an HVAC engineer to read the schematics and explain all the details in the schematic
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

Need to perfectly time the LED lights on a cycle wheel to form an arc irrespective of the RPM of the wheel. we expect you to:- - Design the PCB - Provide circuit diagram - Suggestion on better sensors that can be used to perform this activity
The pcb design that i made has an small error and i need someone to help me figure out the issue. Its a combination of Arduino Nano MCP328P + MCP2515 CANBUS board but in a smaller size with lots of extra arduino nano stuff removed as i will not be needing it. MCP328P chip and FDTI chip do communicate with PC and all digital/analog in/outs work quite well so no issues there, however the MCP2515 part is not able to receive nor send CANBUS messages so i am guessing within this simple pcb design i made an error that i cannot figure what is.
I have a motorized TV lift, i am able to control the lift by nodemcu. But now i want to make this device in production as want to sell this module. And my client will easily connect it with google home and alexa, and control the lift
Project based on IOT and PCB designing. Need a IOT engineer who can design me a compact PCB for home automation project it should be successful with all the elements perfectly placed and should give a best outcome. please look the reference videos pcb gerber file - youtube video- ----------------------------------
Developer a microcontroller (in the beginning could be Arduino, etc. - later own controller hw) application that does control temperature on a device and modifies performance settings (volt, amps) based on some characteristics. It uses input and output information via a touch display or OLED/steering buttons. Needs to control also a few actuators/relays.
I have a Custom Mechanical Keyboard which has switches soldered into a PCB by two solder joints. As I have little experience Desoldering I was looking for someone on here who could do a good job Desoldering the board and sending the two parts back separately.
Requiero realizar la conexión automática entre dos ESP-01. Funciones deseadas: - Pulsar botón (transmisor-maestro), conexión automática entre el transmisor y el receptor - Mantener conectividad estable al estar cerca (1 o 2 metros) - Enviar a dormir el dispositivo ESP-01 (transmisor-maestro) para ahorro de batería. (siempre deben estar conectados) - Encender un led (receptor-esclavo) cuando se pierda la conexión (solo se debe perder la conexión si los ESP-01 están fuera de rango en metros)
