I had this little project in mind but after chewing on it for a while I figured that to achieve my goal I would need more pins than the Arduino Uno can offer. I started looking at what my options were and soon I found something that looked very promising – shift registers (yes, I ...
like delay(), millis() and micros(). If you change Timer0 registers, this may influence the Arduino timer function. So you should know what you are doing. Timer1: Timer1 is a 16bit timer. In the Arduino world the Servo library uses Timer1 on Arduino Uno (Timer5 ...
The screenshot below displays the response timing of a synchronous readCO2() call which takes 22.1ms on an Arduino UNO: 9.4ms: Transmit 9 Bytes at 9600 baud 3.2ms: MH-Z19B to process command 9.3ms: Return response 9 Bytes at 9600 baud ...
controlling the valves from a browser was the bear minimum I would expect and Gardena does not offer this functionality. (My friend) dd-wrt even allowed me to re-use an old router of mine and made the whole thing wireless.
