$30-250 USD

Paid on delivery
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

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!

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
