M+1 full adders
A full adder takes two inputs plus carry in and produces one output plus carry out. You need four full adders to add two 4 bit words. (No half adders required.)Or: for the lowest bit you can use a half-adder (no input carry).
2 input and 1 output
many micro controllers can be programmed by a simple serial port interface you can construct yourself. They also have programming devices you can buy that use either serial or USB ports. If you have code you know is good, often places that sell the microcontrollers will flash the code onto them for you for a nominal fee, saving you a bunch of time if you are getting like 100 of them.

It took three full years to construct the Titanic, from March 1909 to March 1912.
binary addition of two bits is called a half adder ,and of three bits is called a full adder to be more lucid in my explanation a half adder doesnot consider a carry generated from the previous added pair of binary numbers consider an example :- A=a1a2a3a4 + B=b1b2b3b4 = sum=s1s2s3s4 the actual addition procedure is a4 and b4 are added first then the sum is stored in s4 and the generated carry is added with a3 and b3 and the process continues so addition of a4 and b4 where there is no input carry is carried out by half adder and the addition of c1+a3+b3 is carried out by full adder. but practiclly the first situation a4+b4 can be considered as a4+b4+0 so all the addition can be performed by full adder it self truth table for both half adder A B s c 0 0 0 0 0 1 1 0 1 0 1 0 1 1 0 1 for full adder c1 A B s c 0 0 0 0 0 0 0 1 1 0 0 1 0 1 0 0 1 1 0 1 1 0 0 1 0 1 0 1 0 1 1 1 0 0 1 1 1 1 1 1 where s and c can be viewed as the sum and carry on solving the k-map for full adder and half adder we can obtain the fuctions of sum and carry

No, the adder snake is not currently classified as endangered. However, they are protected in many areas due to declining populations and threats such as habitat loss and fragmentation. Conservation efforts are in place to monitor and protect adder populations.
about 200 people die from adder bites each year in the uk
