Write Arduino code sketch (software) and provide a connection diagram that achieves the following goals with an Arduino Mega 2560 board: 1. Display temperatures (user switchable Celsius or Fahrenheit) and fan speeds in rpm (in real time) on the OLED display screen. 2. Develop a calibration method for each of the 10K Thermistor sensors that are being used as temperature sensors for this project. This method is used to achieve as accurate temperature readings as possible from each sensor. ("Thermistor" is a thermal resistor - meaning it's a resistor that changes its resistance with temperature.) 3. The Pulse-Width-Modulated computer fans automatically adjust their speed according to the temperature sensor readings. For example, Higher Temperature = higher fan speed Lower Temperature = lower fan speed (Adjustable temperature limits and delta will help prevent the fans from changing speeds too much and maintain more stable fan speeds.) Hardware Available: A) There are 5 total Thermistors (10K resistance @ ~ 25 degrees Celsius) that are being used as temperature sensors. (Top 180 mm radiator has 2 temperature Sensors [Input and Output]. Middle 120mm radiator has 1 temperature sensor [Output]. Last Radiator has both Input and Output Temperature Sensors). B) 3 Pulse-Width-Modulated Computer Fans (PWM) 180mm Fan: 180mmx18mm Silverstone FW181 (Voltage 12 V, Input Current (0.04 ~ 0.54A) [@ max speed], Input Power (0.24 ~ 9.18W) [@max speed]) 120mm Fans: 120mmx25mm COOLER MASTER 4-BMBS-20PK-R0 (Voltage 12 V, Current (Ampere) 0.36A Max., Power Consumption 4.32 W Max.) C) Arduino Mega 2560 Board D) Five 10K Resistors and Five 10K (@ 25 degrees C) Thermistor temperature sensors E) 20x4 Character [login to view URL] i2C OLED display screen (Op204i) F) Solid Wire

Dear Hiring Manager, I've already done a similar project on Arduino Mega 2560 that also has 3 10k temperature sensors and controls the operation of fans and other appliances. Moreover it has the functionality of usb and wifi as well. I've high expertise in the following: Arduino, Raspberry Pi, PIC/ATMEL microcontrollers, electronics. If there is any project regarding these, then there is no choice better than me, and I guarantee you'll be 110% satisfied with my work. You can have a look at my profile and read the wonderful reviews my clients have posted about my works. Here are the top qualities my clients love to have: My Qualities: 1- I make regular communication with the clients and provide them updates. 2- I'm quite flexible in working with US times (because most of my clients are from USA). 3- I work honestly and sincerely, and finish the works very responsibly. 4- I take longer than others but don't compromise on the quality of work. That's why I guarantee 110% satisfaction. 5- I provide free support (for up to 30 days) even after the completion of the project. 6- Freelancing is my profession and I want to grow my business from it, so I look forward to long-term projects. However I do work on short-term projects as well (most of my projects are short-term). Sir with this project I promise you'll have the most wonderful experience with me and we'll have strong long term relations. Regards. Faraz Ahmad

@gab3iel

hi, it would be tricky to set an exact fan speed, unless the fans provide feedback, and then we would need an interrupt for each fan, besides the pwm output. please contact me to discuss details!

@ZaychenkoYura

Hello! I would like to help you with your project. I have an existing similar project with computer fan and temperature measurement. But in my project is used 16x2 screen and only one pwm controlled fan. So I can do your task in a short time. But I would like to know the type of your fan, because there is no posibility for direct measurement of fan speed. If it is needed, I can demonstrate video of existing project
