Next we connected the water flow sensor’s output to the Arduino board (filled with the sketch) and allowed water flow through the water flow sensor at a steady rate of about 1 Litre/minute. Besides ...

Here, the three LEDs are directly connected to Arduino pins with independent current limiting resistors (R1 ... By increasing or decreasing pulse width, the controller regulates energy flow to the LED ...

If you’ve messed with Arduino, the inexpensive ... switching high voltage and high current. So I thought I had to come forward with a product.” One board costs $129 and he’s trying to ...
