Again, transistor switch. Can you build transistor switch with DC motor circuit? – DC motor with 5V power supply directly from Arduino – TIP122 transistor – protection diode – push button – pull down resistor Challenge: When you press the button once, the motor starts to turn. When you press the button the second time, […]
Once again, Do you remember how to read sensors -digital sensor (PushButton) -analog sensor (photoCell) Challenge: Connect push button or photocell to your Arduino and control a LED connected to Arduino RGB LED RGB LED is something like 3 LED (red, green, blue) in one with common cathode or anode (The one we have is […]
Once again, Do you remember how to read sensors -digital sensor (PushButton) -analog sensor (photoCell) Challenge: Connect push button or photocell to your Arduino and check the input on SerialMonitor. ——code——— int photocellValue=0; int buttonValue=0; int buttonPin=5; int photocellPin=A4; // the setup routine runs once when you press reset: void setup() { // initialize serial […]
