Description: Three-person voting device, designed with 74HC00 + 74HC10, three judges each control one of the three buttons S1, S2, S3, with the principle of minority subordinate to the majority of voting events, press agree, otherwise disagree. If the vote is passed, the LED will light up, otherwise it will not light up. Circuit board size: 5.5 x 2.7CM Supply voltage: DC3-6V Package Included: 3 x DIY Three Person Voter Module Kit

Working principle: Using the SMD CD4060 control 12 red, yellow and green LED flashing, adjust RP1 can change the speed of flashing, while the music chip issued a wonderful music. The kit uses SMD components and plug-in components, is ideal for practical training requirements. The CD4060 consists of an oscillator and a 14-bit binary serial counter bit. The oscillator can be configured as an RC or crystal oscillator. When CR (pin 12) is high level, the counter is cleared. All counter bits are master-slave flip-flops. The counter counts on the falling edge of the CP (9-11 pin) pulse in binary. Since the Schmitt trigger is used at the clock input, all inputs and outputs are buffered for unlimited pulse rise and fall times. Note: This is a DIY kit, need to be assembly. Not supply installation manual. Package included: 3 x SMD Music LED Light Kit Complete assembly for reference only:

Description: The dimming circuit can make the voltage at both ends of the bulb change in the range of tens to 200 volts, and the dimming effect is remarkable. In the circuit, R2, R3, R4, RP1, C1 and VT1 constitute a single junction transistor oscillator circuit, which is used to generate trigger pulses.When the capacitor is charged by R4 and RP1, the voltage Ue increases gradually. When the Ue reaches the peak voltage, e B1 turns on and the voltage on the capacitor outputs a pulse voltage to R2 via e-b1. Because the resistance of R4 and RP1 is large, when the voltage on capacitor drops to the trough voltage, the current supplied by R4 and RP1 is less than the trough current, which can not meet the conduction requirements, so the single-junction transistor restores the blocking state. Thereafter, the capacitor recharges and repeats the above process. As a result, a sawtooth wavy voltage is formed on the capacitor and a pulse voltage is formed on R2. During each half cycle of AC voltage, the single-junction transistor will output this pulse to trigger the gate of the thyristor, which will turn on the thyristor and light up the lamp. Change the resistance value of RP1, that is, change the oscillation frequency of sawtooth wave, thus change the size of thyristor conduction angle, and then change the output voltage of controlled rectifier circuit to achieve the purpose of adjusting the brightness of the bulb.
