This is tutorial number 1 from our series of Arduino tutorials and in this part I will talk about blinking an LED using the one already available on the Arduino Uno board or using an external LED to ...

It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of oscillato… ...

You can control the brightness of these LEDs using variable resistors VR1, VR2 and VR3 respectively. Parts Needed. Arduino UNO board – 1 ; 5mm LEDs Red, Green, Blue – each 1 ; 100K Variable resistor – ...

Before the software part, let's first set up the circuit to connect the LED to the Arduino. The completed circuit should look like Figure 2. Figure 2. Circuit for a Single LED Blink Next, in your ...

The DS2 LED on your board should now blink on or off every second. Next Steps If you have the Grove Starter Kit Plus Intel IoT Edition, here's how you add sensors: ...

Using only an ultra-bright white LED, red blinking LED, PNP transistor, and a diode, the circuit gives a strong visual indication of current consumption by blinking brighter and more frequently as ...
