To use thetoInt()functionto convert acharto anintin Arduino, you’ll first need to convert thecharto aStringand then use thetoInt()function. voidsetup(){Serial.begin(9600);charcharValue='7';StringstringValue(charValue);intintValue=stringValue.toInt();Serial.println(intValue);}voidloop()...

However, applying the tuning effect to animations required an arduous image conversion workload andcomplex playback code. I was quite surprised when I learned this, as I had wrongly assumed she used theanimated GIF support I had addedto my library. In hindsight I should have remembereddrawBitma...
This example uses a conversion factor from microseconds to seconds, so that you can set the sleep time in theTIME_TO_SLEEPvariable in seconds. In this case, the example will put the ESP32 into deep sleep mode for 5 seconds. Save Data on RTC Memories ...
voidpingHandler(constchar*command){ Serial.println("PONG"); } This will write “PONG” on the serial port. You can also use Step 3: Reading… UnityReading from the serial port is theoretically as easy as writing, since C# offers a very intuitive ...
