Steering toy car with raspberry

Hello everyone! I wanted to put rpi inside of RC toy car and program it to drive itself based on camera input. Firstly I needed to dismantle the car of course. I expected to see servo for steering front wheels left and right but to my surprise there was a standard DC motor. When disconnected from ge...

Re: When to use servo and motor driver

only connect servo signal and gnd to the pi and power the servo from a separate supply, a servo can pull 3-5A when stalled which will reset your pi if powered from the pi. Fortunately I have read about gpio output current but thanks for bringing it up. I will have two separate power sources. One fo...

Re: When to use servo and motor driver

Thank you all for explanation. I used redox s90 servo before to check if pi can handle it but didn't know for sure if it's correct way to do it.

By the way, where is it better to use hardware pwm like in provided adafruit board instead of software pwm from gpio?

When to use servo and motor driver

Hi, I want to make remote control car with camera using RPi0. I noticed there are servo drivers like this one: https://www.adafruit.com/product/815 but I don't know when do I need to use it. I mean, I can connect servo control pin to gpio and steer it by software PWM using RPi.GPIO in python. When d...

Re: More Zeros Wednesday

One can observe that the bare boards sell out first, and the kits sell out--generally--in order of increasing cost (an exception to that is the current Pimoroni status where the most expensive kit is out of stock, but the second most expensive on isn't). Nope. Look at details, there are 3 suboption...

Re: Shipment schedules(update?)

Remember that Pi zero isn't manufactured in external factories so it takes time to produce them. We need to be patient. I also want to buy more than one and I didn't buy them this monday but there is nothing more to do than just wait. But considering that there will be stock every week I hope that s...

Shipment schedules(update?)

Hi everyone. I know foundation is tired of all this rant about Pi zero availibility(especially with so many bullshit arguments...) but I wanted to ask for update for this thread from february: https://www.raspberrypi.org/forums/viewtopic.php?t=135081 Is it going to be like said in this thread or dif...
