A middle school design and technology teacher breaks down a three-project unit that nicely overlaps with STEAM content.

Presuming a particular basic LED circuit does require a resistor, though, it will be necessary to subtract the forward voltage drop of the LED from the source voltage, and to apply Ohm's law.

10K trim pot Circuit Diagram - 74HC595 based Circular LED Chaser The working of the circuit is very simple, when the circuit is powered on the 555 timer generates a clock signal that is fed to the Cp ...

In the image below you can see the circuit diagram of the LED blinking hardware setup. Here, we have two LEDs, the positive terminal of red LED is connected with GPIO 27 (pin 13) and positive terminal ...

Part 1 of this three-part series introduced the technical and engineering steps necessary to design an LED display system from individual LED lamps. Part 2 provided the remaining steps needed to ...

Each of the following diagrams illustrates how the same basic circuit can be used to create an LED-lit accessory that can be switched on an off. These circuits are similar to the practice LED circuit ...

In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

The circuit drawn pertains to a regular industrial UPS (Uninterruptible Power Supply), which shows how the batteries take control during an outage in electrical supply or variation beyond the normal ...
