Note: I didn't take thorough notes at the time of doing the lab so I'm recreating it with limited time. I worked with Viviene on the lab and we managed to work through all the assignments.
Digital In / Digital Out
// Code
void setup() {
pinMode(2, INPUT); // set the pushbutton pin to be an input
pinMode(3, OUTPUT); // set the yellow LED pin to be an output
pinMode(4, OUTPUT); // set the red LED pin to be an output
}
void loop() {
// read the pushbutton input:
if (digitalRead(2) == HIGH) {
// if the pushbutton is closed:
digitalWrite(3, HIGH); // turn on the green LED
digitalWrite(4, LOW); // turn off the red LED
}
else {
// if the switch is open:
digitalWrite(3, LOW); // turn off the green LED
digitalWrite(4, HIGH); // turn on the red LED
}
}
Analog with an Arduino
Implemented the analog lab with the force resistors.
const int ledPrimaryPin = 2; // pin that the LED is attached to
const int ledSecondayPin = 3; // pin that the LED is attached to
int analogValueForceResistorA = 0; // value read from the pot
int analogValueForceResistorB = 0; // value read from the pot
int forceA = 0; // force value
int forceB = 0; // PWM pin that the LED is on.
int minn = 100;
int maxx = -100;
void setup() {
// Initialize serial communications at 9600 bps:
Serial.begin(9600);
// Declare the output pins
pinMode(ledPrimaryPin, OUTPUT);
pinMode(ledSecondayPin, OUTPUT);
}
void loop() {
// Declare the input pin
analogValueForceResistorA = analogRead(A0);
analogValueForceResistorB = analogRead(A1);
// map
// 1,2,3,4,5,6,7,8,9,10 => 0 => 255
// 25.5, 51, 76.5 ... 255
// Calculate incoming
forceA = max(0, map(analogValueForceResistorA, 50, 1012, 0, 255));
forceB = max(0, map(analogValueForceResistorB, 50, 1023, 0, 255));
analogWrite(ledPrimaryPin, forceA);
analogWrite(ledSecondayPin, forceB);
// 11111111 255
// Min - Max
minn = min(analogValueForceResistorA, minn);
maxx = max(analogValueForceResistorA, maxx);
Serial.println(minn);
Serial.println(maxx);
}
I followed through on the core lab and then adapted the circuit and sensor readings to work with the Myoware Muscle Kit Sensor. I didn't have to change much. The only thing that was different was that the mapping was form 0 to 10 and I turned the light on after a certain threshold (5)
