That board on Banggood got good reviews and it's fairly cheap. Why not give it a try?

I will thank you!
another question though, the heater is rated for 100W, does it mean that itll draw 8.3A from a 12V power supply? or do I have to limit the heater myself?

nivm200

I cant draw a schematic to something I know theres a better way to do... Im not playing with electricity nor do I even have the parts, im not trying it out, im asking so I can either use my current plans or change them, how will one go about controlling a heating element? PWM will not work here as I...

nivm200

thank you both for the reply, I do not have schematic as there probably better approach to this and something probably is incorrent with my plan,(which is why im here :P ) this is the fan and heater il be using, https://www.banggood.com/100W-12V-60x60mm-DC-PTC-Fan-Heater-Constant-Temperature-Incubat...

Hello! I want to control a heating element (100w) to heat air in a box to about 30 degrees (celcius), how will I do it with a raspberry pi? the heating element consist of a fan and the heater, 4 wires, 2 for the fan, 2 for the heater, I have a 12V 30A power supply that the fan is connected to throug...

Hey, Is it possible to run 2 (or more) CMOS or CCD camera through the RPi and record their video? I dont need full resolution out of them, and only need 15 FPS or 10FPS, resolution would be 352 x 240, CIF. the camera would be an FPV camera, such as http://www.banggood.com/600TVL-8_0MP-14-2_8mm-CMOS-...

Hey, Can someone explain why do some people control motor directly from the RPi (PWM), and why some people connect them to a motor controller (such as L298N)? Also, does anyone know any product from Banggood (http://www.banggood.com/) that will be able to expand the GPIO pins via I2C? I tried lookin...

thank you!

any example code for threads/timers? I will add me code once il get home.

I want to run a loop with a delay every time the code in it is called, but whenever I use time.sleep() I can only run one loop and I need more than 1 loop to run at certain time... how can I associate the the time for the loop only and not the rest of the code?

how can I set the servo angle in degrees (1-180) using the servo hat? thank you very much. edit: I found a way to limit the servo speed , I will attach the code soon for people who might need it in the future, however now I have 2 different problems.. 1.I need few servos to start at different times ...

nivm200

How can one limit servo speed? ie turn 90 degrees in 5 seconds... Im using the RPi servo hat by Adafruit.

nivm200

Thank you very much

nivm200

thank you, how do you copy from a certain directory into the default directory of the RPi? I can find and locate the file, but I want to copy it to the same place where you get when the RPi starts...

nivm200

Hello, Ive bought the servo HAT by adafruit and checked the example code, after using it, it seem like it only work in the directory of the example code and cannot be moved, the problem is that the first line of the code is: from Adafruit_PWM_Servo_Driver import PWM and the RPi looks for it in diffe...

nivm200

I found what I needed

Im leaving this here as reference for anyone else that might look for such a thing and find this thread. cheers!

thanks for helping! I looked into it a bit and there isnt much information about wheels encoders, how would I accualy read them using the RPi?

nivm200

Hey! does anyone know a way I could track the position of a motor (or servo, or stepper motor, any would do)? I need it to be somewhat compact and 6 motors all togther at once, now - the motor might be stopt by an object and I would need to track that too...
any ideas? thanks!

nivm200

Mikronauts, thank you for taking your time and helping me out! I think I will go with the Adafruit servo hat as it seem to be the easiest way to go. Do you accualy own mikronauts.com? if so, I do have to say, good job with the helping (it might sound obvious for some)! usually people try to advertis...

nivm200

mikronauts, BMS doug, I know this question is stupid, but which expansion board is the simplest where I can simply "plug n' play" and will allow me to control the servos? I cant express how stupid I feel about this question as usually I do the search myself and most of the time get the correct answe...

nivm200

thank you for replaying,
Im sory to bother but have you saw any in-depth tutorial of how to add more pins to the pi?
Im not quite sure how to do so and internet search didnt yield much

nivm200

Hey, Im working on a small project that would require me to control 12 servos (independently from one another, and up to 16 in the future) while reading records from a gyroscope... I found a gyroscope that is small, light-weight, and cheap, do you guys think its even worth it? or is it too cheap/sma...

nivm200

This isnt a continous rotation servo, its a standard 0-180 degrees servo despite the R at the end of its name, you can google it if you dont believe me.

nivm200

Hey, Im relatively new to the pi, so please go easy on me :P I know someone asked it before, and I tried googling it already for two days but couldnt find anything that helped me. I bought few towerpro sg92r as Id like to make 4 legged "walking" machine, but, Im facing 3 problems here. 1. I cant get...
