We are looking for a talented electronics engineer with experience in circuit design, firmware, and embedded systems to help us develop a USB to PWM I/O device. This Device will take input through a single USB Port and gives 32 X PWM outputs. This device will have 32 GND PIN and Maximum possible 3.3Volt Pins and Maximum Possible 5.5 Volt Pins. Remember using this I will control ESC of a BLDC motor. That means - this device will be connected with my PC using USB and the ESC will be connected with the PWM Pin of the device. Now using Python and C/C++ I will increase or decrease the Speed of the BLDC motor. The ideal candidate must have experience in hardware design and PCB layout, as well as proficiency in programming languages such as C++ and Python. Additionally, ...

I want to modify the PWM to devlope this projects. please have a look on the attached file.

I am looking for a programmer to write some simple arduino code for me. The goal of the code is to maintain a PWM duty as a result of an ADC feedback reading. The maximum frequency that it needs to be able to produce is PWM. The desired output from the code is Pulse Width Modulation (PWM). I am looking for expertise in coding and programming with Arduino and the ability to adhere to the requirements. If you have experience in this field, please bid on the project.

The first code on the Arduino sets up an output pin to generate a PWM signal in open drain mode (OUTPUT_OPEN_DRAIN) at a frequency of 10 kHz and a duty cycle of 50%. Then the code enters an infinite loop, in which it reads the ADC value from pin A1, outputs it to the serial port and, depending on the ADC value, either generates a PWM signal on a pin with the specified duty cycle, or turns off the PWM signal and puts the pin in mode open drain. The cycle repeats with a delay of 10 milliseconds. The second code establishes a connection with another ESP8266, which must be configured as a server. This code connects to a server located at IP address and using port 5000 for a TCP/IP connection. If another ESP8266 is set to a different IP address or port, you need to change...

... I have created a prototype, have wired it using a lot of wires from the electronic shop and have then written a program on Arduino and the stuff works. It is a LOT of wires, it took ages to assemble and is obviously not the way to bring the prototype forward. I would need someone to design a PCB board which would basically do exactly the stuff that I have drawn (please note that I would need a PWM on the stirrer as well, this is not present in the current wiring scheme). Everything written in green in the wiring scheme is in a different part of the prototype (ie in a physically different container, linked by a 5 way cable). The whole project is on a 12 V circuit apart from the two UV lights which need 38 V. Input is 12 V. Upon project assignment I will send the designs with t...

Short summary: The main motor is 14W, 230V working as fan for bath room. Controller needs an output to drive this fan ON and OFF by relais. As bonus, instead of relais a 230V PWM output to adjust the power. with logic of timer and humidity sensor. After ~15min always over ~60% humidity the fan starts. if user will press button it can be switched off and on manually. On always runs for ~30min, then switches off and goes to auto-mode. +Air door on / off (5V 40mA).

...know of a currently existing COTS solution, that knowledge is valuable to me. Your design should assume that the Tristar must not see any voltages in excess of 525 Volts under any foreseeable circumstances, giving a 75 V safety margin (ie. 525 VDC safe max., to 600 VDC danger catastrophic destruction limit). Assume the bridge rectifier will operate at a nominal 300 VDC, with the dump heaters on PWM between 300 and 400, and fully on at 400 VDC, or higher. Therefore, your design device will normally operate in the 400 to 525 VDC range, and will passively monitor voltages at voltages lower than 400 volts.. There are 10 amp fuses on the 3 phase AC side. There are COTS surge arrestors (Delta and Midnite Sun) already installed on the system's AC, rectified 600 VDC, and the 48 VB...

We are using Analog card for controlling constant current or constant voltage of a power source using current or voltage feedback . This is an IGBT based PWM controlled power source . Switching frequency is in the range of 20Khz to 100 Khz. We want to have a digital control in place of analog control which uses IC and hundreds of other components. The controller has to deliver current or voltage as set with all protections against over current, over voltage, short circuit etc.

I need an programming code for this following task. Task: The illuminance of a billboard is to be adjusted depending on the the brightness. The darker it gets, the brighter the billboard should shine. The implementation can be done by a phototransistor to detect the brightness and the output of the corresponding luminosity with the help of a PWM signal to a series of LEDs. The adjustment of the luminosity, can be done step by step. It is sufficient if 3 brightness levels are output. When pressing an "off button", the lighting is switched off. ldr A5 ledPin 9 button 8

I have a linier actuator with optical feedback and pwm control. The goal: To extend and retract between two encoder points user definable in the code. Homing on powerup required. Single momentary button (use a counter for extend and retract?) Details Upon extending the actuator will stop at a defined point with a timed delay, then continues to extend to the final encoder count stop point. When it gets close to the stopping point the actuator must slow for a soft stop. Pressing the button a second time will retract the actuator to a final retracted encoder point, soft stopping as well.
