hi im not well expierienced with arduinos and such but i have a class that requires building a machine
i decided with friends to build a cocktail maker
here is my wiring and circuit design
my only question is do i need to add something to prevent anything from getting fried somehow ?
Moderator edit: unnecessary external link removed
arduino will be damaged, you trying to take 5V from the board, don't do this, use external 5v power supply
Please post the picture here. Many helpers don't download unknown material.
Schematics and code are the most interesting things as well as datasheets for motors, drivers, power supplies etc.
am i not supposed to use the 5v port on the arduino ?
you are right it all done now ^^
you are right will try to im using tinkercad
if board is powered from USB, USB allow current up to 500mA, so you may connect some modules, but ...
if you put 7-12V to Vin pin, the 5v will be provided from little regulator, current up to 100mA(China clones even worse), actually it designed for arduino needs, not for additional module, not to mention the bunch of RGB LED
I don't have TinkerCad to try this but it says on their site:
Schematic layouts are available in Tinkercad Circuits. To see it, click the "Schematic View" button in the top toolbar within the Circuits editor
Welcome! The first thing I would do is get a real schematic, if you do not have the CAD (Computer Aided Design) package KiCad is very good and free. It is not a learn it in one night package. I would use a different bridge, that one will lose about 3 volts from the source to the motor. This is burnt up as heat. How do you plan on powering this? The UNO cannot provide enough power for the motors and I am not sure you laptop USB port can either. Here are some thing to check:
Gil's Crispy Critter Rules, they apply to processor hardware:
Rule #1. A Power Supply the Arduino is NOT!
Rule #2. Never Connect Anything Inductive (motor, speaker) to an Arduino!
Rule #3 Don't connecting or disconnecting wires with power on.
Rule #4 Do not apply power to any pin unless you know what you are doing.
Rule #5 Do not exceed maximum Voltages.
Rule #6 Many will not power a transmitter.
LaryD's Corollary's
Coro #1 when first starting out, add a 220R resistor in series with both Input and Output pins.
Coro #2 buy a DMM (Digital Multi-meter) to measure voltages, currents and resistance. Violating these rules tends to make crispy critters out of Arduinos.
Hint: It is best to keep the wires under 25cm/10" for good performance.
Let us know how you are doing.
Hi, @mdaprem
Your image has very low resolution, not easy to read.
Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.
TinkerCad should be able to make good informative schematics.
But in a pinch, hand drawn gets a quick job done.

PS. Pen(cil) and ruler.
