#learning electronics

[thestaticroom]

I made a Radio! I am teaching myself robotics and the first lesson I figured I'd learn is soldering. Bought a small soldering kit on Amazon and put this together

The problems I had were these damn wires being finnicky about attaching, the battery compartment not wanting to fit right, and my back killing me afterward but it all came together in the end.

learning C++ and electronics: simple program to calculate Charge (I avg) and number of electrons per given unit of time through copper

/*Date: Feb 28, 2016 **Author: A L **Purpose: This programs takes in Amps and time and returns the **         number of electrons passing through a specific time **         and the current (C) or 1A = 1C\s ** based on information from: **Scherz, P., & Monk, S. (2013). Practical electronics for inventors (3rd ed.). McGraw-Hill. ** */ #include <iostream> #include <math.h>

using namespace std;

int main() {    //init variables    float copper = 0.0;    float timeInSec = 0.0;    float amps = 0.0;    float charge = 0.0;    float numOfElectrons = 0.0;

   //assignments    copper = 1.602 * powf(10.0, -19.0);

   //get user input    cout << "This programs takes in Amps and time and returns the";    cout << "\nnumber of electrons passing through a specific time";    cout << "\nand the current (C) or 1A = 1C\\s." << endl;

   cout << "\nPlease enter the amount of current in amps(A)(eg. 2):";    cin >> amps;    cout << "\nPlease enter the time in seconds (eg. 2):";    cin >> timeInSec;

   //calculations    charge = amps * timeInSec;    numOfElectrons = charge / copper;

//output

   cout << endl << "\nThe charge that passes a given point in " << timeInSec << " seconds is: " << charge << "C";    cout << "\n The number of electrons passing through with a charge of " << charge << "C" << " is " << numOfElectrons;

   return 0; }
