To carry out this project in your own laboratory, download the manual here, electronic diagrams and placement of components on breadboard in.

What is the value of resistor R3 for the circuit below?Ī variant of location of components for the breadboard for problem 3, is presented below: Download the manual and electronic diagrams What is the value of resistor R2 for the circuit below?Ī variant of location of components on breadboard for problem 2, is presented below: Problem 3 - Lighting three LEDs using the LM7805 The possibility of importing Fritzing circuit models into the simulator.

Voltage drop on LEDs = 1.6V + 1.6V = 3.2V.

LED current consumption = 30mA How do we check if the value of resistance R1 is correct or not?Īpplying the following calculations: Problem 2 - Lighting two LEDs using the LM7805 Ultimate DIY Breadboard Power Supply: For prototyping. Necessary componentsġ x Electronic test board + connecting wiresįor a better understanding of the functionality of the circuit and to achieve this assembly on the breadboard we will need electronic scheme presented below: Placing components on breadboard Issue 1Ĥ. The idea is here to power with a 5V Power supply 12A power and get 6x 2A USB power to charge your Tablet, Smartphone, Raspberry Pi, Arduino.

everyone knows the issue that you always have not enough USB Power connectors. The assembly aims to learn the basics in electronics, in a way that is as interactive as possible, especially on the power supply side of electronic circuits. USBPower a simple print, where you input 5V DC and power up to 6 USB powered devices.

It shows the power supply of an LED using the integrated circuit as a stabilizer LM7805. The project is intended for children between 10 and 15 years old.
