single cycle datapath write to register and memory at same time
Is it possible to alter a single-cycle datapath so that an add instruction not only writes to a register, but also writes to a specified memory address The only...
digital clock
This is digital clock schematic diagram. This circuit is quite complex and quite difficult for a newbie because this circuit uses IC with some a complicated con...
extended counter using cd4017
At the start condition all pin 15 are connected to the ground, so R0 is energized. A 555multivibrator sendsthe clock signalto IC1, which activates the outputs f...
4017 based sequencer
Below that is the clock section. The knob controls the internal oscillator`s speed, and that can be voltage-controlled via the `Speed In` input. Or, you can ins...

24hr clock using logic ics
The count advances as the clock input becomes high (on the rising-edge). Each output Q0-Q9 goes high in turn as counting advances. For some functions (such as f...
High speed data switch circuit
This circuit is a small representation of a very low cost printer sharer i made very long ago. This is as much i can remember of the basic ideas behind the prod...
digital to analog
This can be used to convert a byte sent from a microcontroller to a analog value like say 1. 51 V. At full scale, when all 8 bits are high calibrate to give 2. ...
simple line follower robot logic circuits
Using logic chips we can make the robot`s behavior more interesting and can implement more complex algorithms.....
random number generator game
This electronic game is simulation of one-arm bandit game. Electronics hobbyists will find it very interesting. When toggle switch S1 is in run` position, all s...
low power universal demultiplexer decoder
This is a circuit for universal decoder that has functions as either a dual 1-of-4 decoder or as a single 1-of-8 decoder, depending on the signal applied to the...
