![]() You can choose to power up as many 5V devices as you can find in this way. The ground is connected with the common ground of the battery and the regulator. This document will start by showing you how to access. This document will explain how to use the NI myDAQ instrumentation within the Multisim Circuit Design software, and give you examples on its diagnostic capabilities. The output current is used to charge Arduino Uno through a 5V I/O pin. The myDAQ instruments in Multisim allow you to compare a schematically captured circuit with a prototype of the same design. It’s the most convenient because it’s easily found in local stores. Please refer to the Battery or connector section to learn more.Īs a last note: the most convenient battery to use would be 9 V Alkaline battery, just keep in mind that you are dropping 4 V from the battery if you use it. So you want to keep the drop to the minimum.Īnother perfect battery for this case would be 2S Li-Po battery, the issue here would be the connectors that usually come with these batteries. All the voltage dropped is turned into heat. Which is perfect for our case, we will have voltage drop of 2.4 V. That will provide us with a mean value of 7.4 V. Here we are going to use 2x 3.7 Li-Ion Batteries in series. To learn more about batteries please refer to that section. ![]() ![]() Keep in mind that as the batteries deplete the voltage inside them drops. Important thing here to consider is how big should the input be? The necessary voltage drop for the regulator to work properly is 2V that means that the minimum voltage should be 7V. The circuit for LM7805 will give as an output steady 5V current. ![]()
