The RGB LED will indicate when the steam machine is in the heating process (red LED), it is ready to work (green LED) and when the output valve is active (green LED), for the simulation of the valve I will use the CS-939MG servomotor
<br><h2>Board</h2>
As I will use two outputs, I will use the attiny44 to have more pins output and inputs, for both cases I will use the PWM for the 4 outputs: 3 for the RGB led and one for the servomotor.<br>
A Pulse Width Modulation (PWM) Signal is a method for generating an analog signal using a digital source, this technique is widely used to control the brightness of a LED, the speed of a motor, the angle of rotation of a servomotor, etc.
<a title="PWM diagram"><img class="image center" src="images/week12/pwm.jpg"></a>
<h6>Source: https://www.arduino.cc/en/tutorial/PWM</h6>
The attiny44 use the following pin for PWM: PB2, PA7, PA6 and PA5. For the RGB led I used these pines: PB2, PA8 and PA6, in the case of servomotor, I use the PA5 pin.<br>
In the attiny44<a href="http://ww1.microchip.com/downloads/en/DeviceDoc/doc8006.pdf"> data sheets, especially on the page 175 , the maximum amperage of 60mA. <br>
Reading the data sheets of the output devices we have the following information about amperage:

</div>
Seeing that the maximum and minimum amperages of the microcontroller and the output devices, it is decided to include a voltage regulator to power these devices with an external battery and reach the minimum consumption available. We will see this in group work.<br>
Based on the designs of the assignment, I make my own schematic design of my output board, as shown in the picture.

As described above, I have decided to use an analog and a digital sensor, as I will use these sensors for my final project. Therefore, I reread the attiny44's datasheet to know how to use the analog and digital input pins.<br>

That was the main reason to investigate various codes to get one that approximates the actual temperature. For my project I will use other types of more commercial sensors, which has a simpler measurement as well as a conversion formula easier to interpret and modify.
