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 the va...
