![]() ![]() ![]() Now if I change all of the 10k resistors to say 1k resistors then I get some functionality. However when I try to run the simulator based on the schematics nothing is working in the simulator. Here is an Image of my work in TinkerCad: They are using 1k resistors for all ground or (-) terminal connections. This diagram is using 10k resistors to each of the 6 transistors' B terminals. So I followed this design of the Xor gate and was trying to build this within TinkerCad, however I keep running into a problem. I then found this web page: NPN Transistor Xor Gate that provides the schematics and the bread board wiring setup. However I was struggling with the connections of the green wires that were behind some components from within his video. Originally I was trying to make the Xor gate based on the version by Ben Eater which can be found here: Logic Gates by Ben Eater. and I am currently now working on an Xor gate. So far I have completely made an And, Or and Not gate successfully. I ended up coming across an online virtual simulator by AutoCAD called TinkerCad that allows you to build bread board circuits and to simulate them. I have never wired or soldered a bread board or a circuit before although I do have a background in physics for understanding the Mathematics and Physics portion.Īs a side note I have also followed Ben Eater's videos on youtube for in the process of building an 8-bit pc. I thought this course was a great step in bridging the gap between the Physics part of computational logic to the field software development. I've been following an online web course called Nand2Tetris that takes you through the steps of building basic logical circuits to full ALU and Processor components, that's the first half of their program, the 2nd half then uses that built virtual PC to implement an operating system, a higher level programming language up to using their language to write your own programs in. I am new to this particular stack site but I feel that this is the most appropriate place to ask my question. ![]()
