Today we will make a 5 LED Running circuit can adjust speed by potentiometer. Which LED Chaser circuit like this We’ve created long time ago. But today we try to use arduino. We are writing technical code “LOOP FOR” very interesting. Parts you will needs First of all, we need to have parts below: • Arduino UNO R3 • Potentiometer 100K • Five LEDs • Five 470 ohms resistors • Jumper wires • Breadboard Secondly, see the schematic diagram as Figure 1 Figure 1 Schematic diagram Then, assemble parts on a breadboard and cable to usb port. Figure 2 Circuit …
Today we will as push button switch as toggle switch. When we press the button “on” it will store status “on” hold, although, we will release. Then, we press it again it will “off” and store status “off” as well. How it works and building We want to control LED ON-OFF by button (as toggle switch). So we use schematic as Figure 1 Figure 1 Schematic diagram of The Button become Toggle Switch using Arduino Parts will you needs •Arduino UNO R3 •Normally open pushbutton •one LED •10K resistor •470 ohns resistor •jumper wires •Breadboard Then, we connect parts on …
