This circuit is the logic guessing game circuit use the digital ICs as base of projects. They are used for playing, with 2 players, the first will set logic, and…
This is 2 Digit Simple digital counter circuit using CD4026 as main parts can display with LED 7 segment 0-99 number There is a reset button to restart.
This is Big digital clock circuit without microcontroller, This projects use all CMOS ICs for learn digital and use 7 segment 6 inch LEDs and AC line 50Hz. [...]
The CD4013 or IC-4013 is a CMOS logic chip with two D-Type (DATA) Flip-flops. A clock pulse flow to C (clock pin), will store the data at the D input. Connect clock and a both Q output to make a toggle flip-flop for counting.
Can we use AND and OR logic gate with Diodes? Yes, we can. The past, we have used only a digital logic circuit by IC. But, in truth. We do not need any ICs. Use Switches or Diodes or transistors connected as a logic circuit.
This is an electronic dice circuit. Which looks like a real dice. We use only the press switch being thrown. this is the high-tech toys. Such as, Game PC
