Electronic Dice Kit LED Fun Making DIY Electronic Parts 40*64mm

Parameter Power supply voltage 4 5 5 0V DC voltage Board size 40 64MMFeatures By pressing S1 to simulate rolling a dice the number of points obtained is indicated by 7 LEDs Like the real dice the amount indicates the number of points from 1 6 The electronic dice achieves the same function electronically When the button is pressed each LED will flash After the button is released the flashing speed will become slower and slower and finally stop at a certain point and stop moving so that it can display Points up It should be reminded that the probability of each point is not the same and some points have a higher probability so they are mainly used for welding entertainment Common problem 1 The resistance value should correspond to the mark on the board one by one 2 Pay attention to the positive and negative poles of the LED and the long leg is the positive pole 3 The white side of the diode 1N4007 is the negative electrode the black side of the 1N4148 is the negative electrode and the vertical bar on the board is the negative electrode 4 The electrolytic capacitor pays attention to distinguish the capacitance value and the long leg is the positive pole 5 The chip notch direction and the base notch direction should be consistent with the notch direction marked on the board 6 Do not connect the positive and negative poles of the power supply in reverse and the power supply voltage is DC 4 5 5V Package included 1 x Electronic Dice Kit
