Feature:1. Equipped with corresponding external components and sensors for programming experiments2. The analog input voltage is changed by the potentiometer component, so that the development board can read3. The brightness of the LED light is controlled after the development board is read, very practical4. Basic starter kit suitable for beginners to learn programming, can assist in learning all the resources of the for R3 development board5. This components kit come with stable structure, excellent performance and long service lifeSpecification:Item Type: Components kitVoltage: 5VCurrent: 1AModel: 830 Tie-in breadboard.Package List:1 x 830 Connection Point Breadboard1 x Module1 x Accurate Potentiometer1 x IC 4N351 x IC 74HC5951 x Active Buzzer1 x Passive Buzzer10 x Button1 x RGB LED10 x White LED10 x Yellow LED10 x Blue LED10 x Green LED10 x Red LED1 x 65 Jumper140 x Solderless Jumpers1 x Color Card20 x Jump Wire Male-to-Male2 x Pin Headers (40pins)2 x Photoresistors1 x Thermistor5 x Electrolytic Capacitor (10F 25V)5 x Electrolytic Capacitor (47F 16V)5 x Diode Rectifiers (1N4007)5 x NPN Transistors (PN2222)10 x Resistance (10R)10 x Resistance (100R)10 x Resistance (220R)10 x Resistor (330R)10 x Resistance (1K)10 x Resistance (2K)10 x Resistor (5.1K)10 x Resistance (10K)10 x Resistance (100K)10 x Resistance (1M)Note:Do not use a voltage higher than 9V.
