25 June 2017 - Problem solved. The ribbon cable was not strongly connected. :oops: :evil: :twisted: How much ran have you set aside for the GPU? (gpu_mem in config.txt) When I had ENOSPC, I fixed it by increasing this. Hi thagrol, my gp_mem was 128 I change it now to 256 ....... # uncomment to force...

Prerequisite for using the Servo motor Tower Pro SG90

Hey community, Happy new year. Sorry for asking this question, which I know have already answered it before but I couldn't not find it ( If someone could post me a link would be perfect). My question is what I need to have to run a servo motor. I can run my servo motor directly from the Raspberry Pi...

Controlar la velocidad de los motores dc motor con PCA9685

Hola , Compre un PCA9685 para querer controlar la velocidad de los motores Dc motor. Note this cannot be used for driving anything other than analog (1-2 millisecond pulse drive) servos. DC motors, AC motors and 100% digital servos are not going to work. (Note that most 'digital servos' still use th...

Re: Python Tkinter GUI button hold down

hold_down = root.bind('<ButtonRelease-1>',stop_motor) is not doing what you expect. The function bind sets another function (stop_motor) when the button is released. It should not be called in a loop. http://stackoverflow.com/a/2440643 I try to simulate a do-while for what I found on this answer. I...

Re: Python Tkinter GUI button hold down

One way to do this is to create your own type of button. import Tkinter as tk class MyBtn(tk.Button): # set function to call when pressed def set_down(self,fn): self.bind('<Button-1>',fn) # set function to be called when released def set_up(self,fn): self.bind('<ButtonRelease-1>',fn) class Mainfram...

Re: How do I connect multiple sensors and leds

Thank for your answer and clearing my doubts. So if I want to connect light (leds) something like this Image to my robot car I just need to add a resistor and connect to ground and 5V pin.
