Thesetup()function runs one time, every time you power on your Arduino. This is where you set up everything you need for your program, like what pins should be inputs and outputs. Theloop()function starts after the setup() function has finished and runs over and over again until you t...
Arduino is an open-source electronics platform based on easy-to-use hardware and software. It is an easy tool for fast prototyping, aimed at students without a background in electronics and programming. Generally, we use an Arduino UNO Board for prototyping electronics projects, but ...
How this TDS sensor works is that it is an electronic pen that is able to measure the conductivity of the water as the electrical conductivity of water is directly related to the concentration of dissolved ionized solids in the water. Ions from the dissolved solids in water create the...

But the other, /TWSTEP, switches the controller into and out of double-stepping mode, which is the important function. The other half of the switch is a bit cunning. At first sight, it looks like it won’t do anything much: it grounds the base of the transistor in both positions, ...
Here is an example Arduino sketch for a basic motion detector: const byte pirPin = 3; // PIR connected to pin 3 void setup(){ pinMode(pirPin, INPUT); // Set pin as input Serial.begin(9600); // Start serial monitor } void loop(){ byte state = digitalRead(pirPin); // Read ...
