3. The good/bad old days
●
●
●
●
●
●
MCU of some kind
Some clock source usually crystal
Chip programmer.
Serial level converter 5V or 3.3V to 12V
Breadboard
Development toolchain
5. Arduino - what do you get?
●

●
●
●
●
●
Atmega 168/328/644p/1284
Some sort of serial to USB capability
5V voltage stabilizer
easy to connect headers
2 leds and 1 switch
somewhat working development library
IDE
14. How does the code look like?
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}
15. code part 2
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000);
// wait for a second
digitalWrite(led, LOW);
delay(1000);
}
// turn the LED off by making the voltage LOW
// wait for a second
16. Code was supposed to be C++,
where are the includes?
● Arduino IDE hides all the complexity.
● IF it breaks, it breaks and you get to keep all
the pieces
● It breaks.
17. GSM modules

RTFM and then read it again.
Then find an older/newer manual and read it.
Also compare to previous HW version.
Never ask your Telco for any QOS class
