Im having problems in turning on the pic16. Whenever it is connected to peripheral components such as h bridges, ultrasonic sensors and the GPIO pins of the raspberry pi as inputs and outputs, it does not turn on instantly. I still need to turn the vdd on and off before it starts. What can be the problem?

Okay thanks! May i ask what the capacitor does to the operation? and should i put resistors on certain outputs? Because when an LED is in parallel with some outputs, such as the hbridge for example, it does not activate as well.

in the 80's, I designed a crane for a model railroad for someone. During design, I was using a linear supply and sometimes the processor would not reset. Later I used a switching supply whose rise-time was pretty quick and I had no problems.
All of the chips were socketed and I notiiced that the RESET pin was driven by a gate. That gate was available in a schmidt trigger version. Once I replaced it, te problem was solved.
I can no longer count the amount of times Verizon has said to turn the power on and off of your modem. An early Westel modem had a power switch. The latter one did not.
I did change things so that my internet Infrstructure is mostly powered by a UPS system except for a repeater. Now, all issues are Verizon;s fault. Including, today's. I suspect that after a planned upgrade this fall, I'll put together a low voltage UPS from a commercial product.
I suspect Eric is spot on. No one uses reset modules because the consume real estate and at one time they were fairly expensive.
