1. "idle" state: It is the state when the machine is doing nothing and is idle. In "idle" state, if power button is "on" then the state transition takes place from state "idle" to state "a" and the output is low. If power button is "off ", then the state remains in "idle". 2. "a" state: In state "a", if fill_water is 1(that is if the water gets filled) then the state moves to state "b" otherwise it remains in state "a". 3. "b" state: It is the wash state of the machine. In "b" state, if add_det = 1(that is if the detergent is added) then the state moves to state "c" otherwise remain at state "b". 4. "c" state: It is the rinse state...
I have a mechanism that can manufacture the rotors for the generator . I need the coils and the capacitor designed so the rotors rotate and collect the dc power renerated by the coils in multi capacitors . Then through the switch design this is released into the batteries as a charge . As one capicitor is discoraging another is charging . As there will be multi coils there must be multi capacitors to keep this process rotating . And it must be design for safety as there will be a lot of power being renerated and stored for release . This must be able to charge a 48v or 52v battery ok . Can you design if not i will put this back here to get others to design . But either way you must work with them to design capacitors and system to have the battery switch also switch output of capacitors in...

I am designing two PCBs (a RF emitter and a RF receiver) and I would like to find someone to give me a hand with it. A summary of specs is presented below: - The emitter (Tx pcb) it is like a keyfob. It should incorporate an encoder (HT12D or similar) along with an RF emitter IC and a PCB printed antenna. This board will be powered with a coin cell (3V). There will be only 2 inputs coming into the encoder. - The receiver (Rx pcb) should incorporate a decoder (HT12E or similar) along with a RF receiver IC and a PCB printed antenna. This board will be powered with a single LiPo Battery (3.7V). There will be 4 outputs. This board should also incorporate a LiPo charging management circuit (TP4056 + DW01 + FS8205) and a DC-DC boost IC (MT3608 or similar) since one of the outputs requires 12...
I am looking for a labview programmer who knows how to use these Labview 2018 NI-CAN NI-XNET NI-SWITCH NI-SCOPE i need someone with Electrical Engineering background to help me understand a program someone else written and will need some modifications to it. this will be a long term project, will pay per hour. also if the project needed to be use on my computer, we must need to zoom in and you have to work from my computer. thank you
We are looking automatic wire cutting and stripping machine which can do this job from 0.1 mm wire ( copper wire) upto 6 mm sq and of different lengths. The machine should not use any hydraulic and pneumatic system for Operation. We would be able to give input to the machine through the push button available and also directly through the computer or data stick in case of bulk requirement ( different cable length). If the machine can itself take different cable ( sq mm) and cut it into desired length as per table or input provided in bulk would be great.
Hi, Need some help in transferring & transitioning analog circuits to hardware, and have little to no experience in assembling the components on a breadboard. the analog circuit on proteus looks fine so just need help to transfer it to the hardware part through a series of zoom calls until we reach the end result.
Internet of Things (IOT) specialist required for design work. Strong skills in computer systems and communication protocols required. Need to work on a design for a remote weather station which is required to communicate to an application.

This project is to adapt an MPLAB project from a PIC32MX795F512 to a PIC32MX675F512. The previous project was completed on the Microchip Ethernet Starter Kit II and is an Ethernet 2 Serial project. There has been a new pcb built with the 675 but with many of the same components as found on the Starter Kit. The new board has some pin changes from the Starter Kit. As much as possible has been kept the same. The new board does have more capabilities than the old Starter Kit. The new capabilities will need to be implemented as a separate project after the basics have been achieved with this project. A document outlining my general communications policy and another document showing the pin changes will be included in this project. Please communicate any difficulties you may have wit...
Hi, Looking for writers, who must have worked on these board: Raspberry Pi, STM32, Arduino, PIC etc. Its a long term job so looking for low rates. Mention your technical background in the bid or recent projects. Thanks.
We are looking for an experienced Electrical Engineer with knowledge of food/automation equipment to help validate heater circuit conversion for the Australian market. We make food forming equipment for the US market. Our specifications use 240VAC, 3-phase, 60 Hz to power to energize a hydraulic ram (motor) and to supply single phase voltage directly to the heaters in our forming dies. We also transform the 240VAC to 120VAC for control circuitry. The available power in Australia is 415VAC, 3-phase, 50 Hz. We have swapped motor components to accommodate, and our controls transformer can convert this power to 120VAC. However, we need to validate our design ideas for our forming die heaters is appropriate, a special challenge given current supply constraints are limiting certain options...

Generate new code for an ARM series MCU (likely the ATSAME70J19B). Two processors on two separate PCBs will monitor GPIO pins for digital and analog inputs and comparing those values to alarm set points and annunciating alarm status via LED outputs (about 20; green=good, red=alarm). The two micros will communicate between each other via serial ports (converted to RS485 via single chip convertor). A couple other features such as detecting physical key turn-on and time-out-timers will be required. PCBs are being laid out now. Coding should start right away. Will include Ethernet port and Simple GUI for viewing/clearing alarms.

This report introduces the wireless sensor interface project of the SEP group project. The objective of the project is to develop a system to collect data from sensors, and to transmit this data wirelessly to a node which passes the data to a PC. Wireless transmission methods have been investigated, and it was decided that a proprietary protocol would be designed. A TDMA based protocol has been designed. Sensor tests have been performed, and the protocol has been designed and detailed in this report. This report also discusses the progress made to date on the project, and proposes a timeline for the completion of the projects

It should have input power-factor above 0.9. It should have output ripple voltage less than 100mVpp. It should have low cost PWM controller with external power switch. It should be compliant with global EMI/EMC standards. It should be compact as possible on single PCB.
Main idea. To have multiple buttons around a office/home and when someone presses it a blink/signal will occur on the units like a common signal for an event. To ACK the signal everyone will need to press the button to confirm. This is a MVP concept design and I will add more functionality later. The only HMI will be a button and a LED (maybe RGB) so all info will be via that interface I will do all HW myself and want a fully functional software delivered. Assume the freelancer have this stuff at home to laborate and test the HW setup for a secure and proper debugging.
Hi, i need a same day turnaround for a program for a linear actuator contoller using esp32-wroom32D. I have a custom pcb with the esp, relays, power, eol sensors and led/sounder output, and would like it coding so that a bluetooth remote (used for a phone camera shutter) can trigger the actuator to extend or retract. I have been let down by my engineer and need to get this running today. Thanks!

Previous microcontroller experience a plus. Looking forward to hearing from you!
first the ultrasonic will detect the water level, if satisfied then start an internal timer and turn on the second relay for 5 minutes. Next, the proximity sensor will detect the distance of the fluid and control the third relay. Lastly, a tds sensor will tell whether to open the fourth relay or open the first relay whereby activate the ultrasonic sensor again
