Lesson 5: Digital I/O

Also uses switches for input and LEDs for output. Click on a switch square with "0" to toggle. A half adder adds two bits.
The output bit "s" is the sum, "c" is the carry. You can either build a half adder using two basic gates or you just use the half adder element. The full adder does the same as the half adder, but can add three bits. You can build a full adder using two half adders and an OR gate. Or just use the full adder element. It can save a single bit. D-Latches have one input connector for data and one clock connector. On falling edge the new 4 digit yellow binary counter gets stored.
In simulation mode you can emit clock 4 digit yellow binary counter using the clock controls on the left side. You can build a simple 4-bit register using 4 d-latches. In this sample all latches are controlled by the same clock signal. A binary counter increases its output value by one on each clock tick.
In this sample 4 d-latches are used. Only the first latch is connected to the clock, the other ones are using the output of the previous latch as clock signal. In this sample a diode matrix is used to map from 4 different traffic light phases red, red-yellow, green, yellow to the proper light. A diode only let signals pass from horizontal to vertical wires.
Adds two 4-Bit numbers. All carry bits are passed to the next full adder. The last carry bit integer overflow is the shown next to the output. 4 digit yellow binary counter the best stock option trading books sample, but serial implementation.
A 2-bit counter with multiplexer selects the correct input bits. Afterward both bits gets added to the previous carry bit and the result is saved in a shifting register.
You can create a copy of this 4 digit yellow binary counter in 4 digit yellow binary counter workspace. You will be the owner of the board and can set up your own team of collaborators.
