On the Arduino Uno board used for this example, pin 13 has an LED connected to it — therefore you should see a tiny orange LED on your Arduino switch on. Click the upload button in the IDE and wait for it to say ‘Done uploading’ before doing anything else....
Nevertheless, in order to keep the electronics components organized and get rid of the wiring mess, I designed a custom PCB using the EasyEDA free online circuit design software. This PCB will actually act as an Arduino MEGA shield because we will be able to directly connect it on top of ...
The MQ-3 Sensor is popular among novices since it is used in mostArduino projects to detect Alcohol. These are also low-cost, simple-to-use sensors with a wide detecting range that may be narrowed to change sensitivity. The MQ-3 Sensor's component marks are shown below. The MQ-3 Alcoho...

For a LOW pulse, just swap HIGH and LOW in the above description. Arduino PulseIn Delay You can see from the way that pulseIn works (see above) that it is dependent on the input signal. If you start the function while the input is active the function will have to wait. There's no ...
UnityTo initialise the serial port in C#, we need its address (orport) and speed (also calledbaud rate). usingSystem.IO.Ports; stream =newSerialPort("COM4",9600); stream.ReadTimeout=50; stream.Open(); While the baud rate is determined by the Arduino code, we cannot chose the name ...
