![]() Run the simulation and take a screen capture of the circuit, multimeter and measurement taking care to include the date/time stamp in the lower left corner of your. Step 3: Place a multimeter across R2 to measure the voltage across R2. ![]() Add a title to the top of your screen capture. Special thanks to my friends Nick Arner and Johnny Wang for helping me fix stuff. Paste this screen capture into your Lab Report (word doc). Thanks to this video tutorial for helping me figure out the electric circuit. ![]() Testing with a 9V battery will fry your Arduino. By limiting the electric current flowing to that pin, you’ll improve the contrast of the screen.Īlso important note: In this voltmeter, whatever voltage you test will go as a direct input to the Arduino, so you should only test stuff that is in the range of volts that Arduino can safely handle (0–5V). Testing a 1.5V AA battery.Īlso, if you want to make the reading on the LCD more legible, put a 1k ohm resistor in the path to Pin 3 (which is for contrast adjustments). Finally, we do setup with the Serial monitor (which is a really useful tool in Arduino! Sort of like debug console), convert the analog voltage to digital voltage, and print (display) that value to the LCD screen.Īnd that’s it! Go and test out various batteries and points! Here are photos from some tests I did: Neutral wires. This is called as a Capture and Simulate environment because you Capture your schematic by drawing it in MultiSim and then you Simulate it. You should see a screen similar to figure 1 below. Next, we create two more variables for the voltage, and then a variable of type LiquidCrystal. Once you have access to MultiSim, Double-click with the left mouse button (henceforth referred to as Double-click)on the icon to start MultSim. So we’re first importing the LCD library, then creating a variable named Vpin (which will be the voltage collected from A5). Paste this screen capture into your Lab Report (word doc). #include int Vpin=A5 float voltage float volts LiquidCrystal lcd(12, 11, 5, 4, 3, 2) void setup() Run the simulation and take a screen capture of the circuit, multimeter and measurement taking care to include the date/time stamp in the lower left corner of your screen. This is the code that you can copy-paste. ![]() We then want to display the results on the LCD screen. We just want to collect the analog signal that the Arduino receives at Pin A5 (or any other analog pin) and convert it to digital.
