Electrical circuit assembly. (Continuation)

Wednesday (04/15^th) - Today we meet in the NMR for the general assembly of the circuit (even in protoboard). Conclude the assembly of the whole circuit and test. Until then everything is working perfectly. You can explain the composition of the circuit as follows: the engine that will move the control of rotation of the base properly connected to 3's CI ULN2003 (in parallel) because the tests have little more than 1A for this engine, we decided to allocate more an IC to ensure the safety and reliability of the circuit. It is important to emphasize that also decided to use a Diode 12V 0.5 W for each ULN2003. Similarly use the same layout engine said to another step that will grab control of the prototype. And finally we have a DC motor that is controlled via two bridging H 12V relays and a ULN2003 IC, which also received a diode for rectification 12V 0.5 W of power.

After testing the circuit to begin programming in C. After a lot of headache to do a functional architecture simplória but the control of each engine separately, including the creation of simple menus for better control of each engine. So we started with the creation of source code with more elaborate conditional comment that the decisions of the user with the options menu.

We consider the present very productive, although we still have much ahead, mainly related to mechanical parts that goes way stop. As I engaged the circuit and software programming for the control, we have ahead to book more meetings for the development and assembling of the parts of the articulated arm.
