Input Devices

Tenth week's Assigment

For this week, the assignments to be accomplish are:

Made an Input board that measures something
Learn something new

Making Schematics and Drawing

I feel more confident making boards and understanding how they work even including the the AVR programming but I still dont understand a lot of parts of the code, I think that that biggest challenge of the academy has been recreating Neil's board using Arduino IDE and making my own code.

on the right I did not found the option for a 1x4 pins in eagle so I had to re-draw it in the illustrator.

As you can see using a image processor software you can

This is how to board looks

This board pushed to learn more about the contraints of the Tiny boards regarding the Serial communication and how we should donwload and #include few libraries, these links help me to understand All About Libraries and to understand what libraries are including how to use them such as Software Serial communication when phisically the pins need to be assign by software and SendOnlySoftware Serial.
Making and designing the board was not too difficult but make to do what you want is the key factor and took me a lot of trial en error, Also realize that having more people working in the same problem can help to find a solution faster.
Thank you to Hyejin SenOnlySoftware part that actually make the board run.

Arduino IDE and Attiny45

Code Used

#include
int trig=3;
int echo=4;
int led=1;
//SoftwareSerial mySerial (1,2); // RX, TX
SendOnlySoftwareSerial mySerial(2); // Tx pin
void setup() {
// put your setup code here, to run once:
mySerial.begin(9600);
pinMode(trig,OUTPUT);
pinMode(echo,INPUT);
pinMode(led,OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
digitalWrite(trig,LOW);
digitalWrite(echo,LOW);
delayMicroseconds(2);
digitalWrite(trig,HIGH);
delayMicroseconds(10);
digitalWrite(trig,LOW);
unsigned long duration=pulseIn(echo,HIGH);
float distance=duration/29.0/2.0;
mySerial.println(distance);
if (distance<10){
digitalWrite(led,HIGH);
}
else{
digitalWrite(led,LOW);
}
delay(200);
}

Lessons Learnt

What I was not able to do this week:

This week was a lot of failures but eventually everything happend

What I did but need to get better at:

Able to edit and make my own code
read successfully the distance
Understanding the laws of quantium mechanics
Be more confident on Making squematics
