Example • Pictures

Example • Sketch #include <Software. Serial. h> #define rx. Pin 3 #define tx. Pin 4 Software. Serial my. Serial(rx. Pin, tx. Pin); void setup() { pin. Mode(3, OUTPUT); my. Serial. begin(9600); }

Example void loop() { int v; v = analog. Read(A 1); my. Serial. print("A 1: "); my. Serial. println(v); delay(500); }

Exercise • Use ATtiny 85 and Serial Monitor to implement Ultrasonic Distance Estimator

Tinker. Cad Debug Mode • Example

Tinker. Cad Debug Mode • Original Sketch : void loop() { if(analog. Read(A 1) > 512) digital. Write(0, HIGH); else digital. Write(0, LOW); }

Tinker. Cad Debug Mode • New Sketch : void loop() { int rv; rv = analog. Read(A 1); if(rv > 512) digital. Write(0, HIGH); else digital. Write(0, LOW); }
