4.5~5V Electronic Dice Kit, DIY LED Dice Kit for Fun Electronic Production Set -20~60℃

Specification:Type:Logical ICWorking Temperature:-20~60Voltage:4.5~5VColor:Blue/GreenMaterial:MetalApplication:Electronic CircuitSize:68*35mm/2.68*1.38inFunction: When power is on, 7 LEDs will randomly display multiple points. The player presses the switches S1 and 7 to light the LEDs. After about 7 seconds, the LEDs will start to flash until the stable point is displayed. The entire first “trial” process endsuit: The circuit is mainly composed of a pulse generator and a decimal counter circuit. The pulse generator and external components are made up of NE555 multivibrator. When you press S1, Q1 turns on, output pulse NE555 3 feet, then outputs CD4017 output high voltage. Different combinations of resistors and transistors can drive 7 LEDs to indicate the number of points. 1-6 pointsonents and Parts Number Value Packaging QuantityPCB 1NE555 Chip U1 NE555 DIP-8 1CD4017 Chip U2 CD4017 DIP-16 1IC Base 8P Straight Cutting 1IC Base 16P Straight Cutting 1Switch Button S1 6*6*5 Straight Cutting Black 1XH2.54-2P Port J1 2P Straight White 1Electrolytic Capacitor(50V/1UF) C1 1 UF 4*7mm 1Ceramic Capacitor C2 104 0.1UF 1Resistor R1 10M 1/4W 1Resistor R2 3.3M 1/4W 1Audion S8550 Q1,Q2 S8550 TO-92 2Resistor R7 1K 1/4W 2Resistor R11 4.7M 1/4W 2Audion S8050 Q3,Q4,Q5 S8050 TO-92 3Resistor R8,R9,R10 470R 1/4W 5Red LED D2,D3,D4,D5,D6 Red 5MM 7Resistor 5,R6,R12,R13,R14 10K 1/4W 10Package List:1*Electric Dice NE555 CD4017 DIY SetNote:As different computers display colors differently, the color of the actual item may vary slightly from the above images.
