Hi so I am a university student, currently trying to make an automatic line launcher for my university project. I am very new to arduino and as such am very confused. My project consists of an arduino controlling 2 6v dc motors, 1 6v servo motor and a 6v solenoid. I really need help to find out if this is plausible and what kind of set up i would need to make this work. I am confused whether or not i would need a breadboard with certain components (like resistors) or anything else. I have 2 6v batteries to power the circuit and was also uncertain if this is enough. I also have an adafruit motor shield v2 to boost the arduinos capabilities.
So I thought that the Adafruit motor shield already has a driver inside that would allow for the servo, motors and solenoids to be controlled. Are you saying that on top of the motor shiled i would have to connect a driver IC onto a breadboard ?
perfect the motor shield has 5 channels but will it be able to control the solenoid and how much voltage batteries would i need for my circuit to work.
Regarding the voltage You are well equipped regarding the motors, servo and solenoid. You ned to check the solenoid for its use of Amperes. Regarding motors and servo, do the same but know the difference between light work and heavy work. Sum up the amperes consumed per hour.
You have to do your own review of the current and voltage ratings of the shield, the motors, the solenoid and the battery or batteries. If you want help with it here, you have to list them here.
So the Servo motor is 6v with 140mA each
the Solenoid is a Pull Action DC D-Frame Solenoid 6v, 3W
the 2 DC motors are each 6v, 170mA , 0.64W
for the arduino
Operating Voltage 5V
Input Voltage (recommended) 7-12
Input Voltage (limits) 6-20V
Digital I/O Pins 14 (of which 6 provide
PWM output)
Analog Input Pins 6
DC Current per I/O Pin 40mA
DC Current for 3.3V Pin 50 mA
For the Adafruit Motor shield
Absolute Maximum Ratings (Ta = 25°C)
Supply voltage, operating voltage 6V
Max Voltage 15V
Input voltage -0.2 to 6
Output voltage 15
Output current ( I out) = 1.2 A
Output current ( Iout peak) = 2 - 3.2 A
Power disipation = 0.89 - 1.36 W
Operating Range (Ta = -20 to 85°C)
Supply voltage = 2.5 V
Output current (H-SW) = 0.4 A
Karma++ to OP. Excellent data collecting work! The shield will work safely as I can se. The remaining question is how You would like to power the Arduino. 6 volt will not work. You can use the computer USB pwr, or a pwr bank, to feed the Arduino. Using a buck conveter, 6 to 5 volt could likely work.
So i cant use my computer to power the arduino via the usb as it needs to self inclosed. The best method i would like is it to be powered by batteries if it would be at all possible. I was just wondering why a 6v battery wont work. Is it because there is not enough voltage, if so then i can aquire higher voltage batteries as they are the easiest option to use in the project.
Also if i were to use a power bank what kind of voltage would i need.
No problem. I use a quite small 6000mAh pwr bank for my mobile speedometer on the museum trains I drive. It runs for several days, say some 48-72 hours. There are much beaffier pwr banks if You need that. Your 6 volt battories will also need charging…...
Code? How did You end up in a project that You have no background to solve? Learning programming is not like buying a package of food.
You have a bag of fun stuff and it can do millions of different things. Soo faar You have told nothing about the target. Nobody can tell out of that.
