    Closed: Re: MCU Selection Help--Urgnet Requirement

    I have created a similar project a long time ago.
    I used an Atmega168.
    I used I2C Bus for to communicate with DHT22 sensors (Humidity and temp).
    Also had an LCD for displaying information...

    You are creating an instance of the object in your main.cpp. It will work you just need to include the header file in your main.cpp - #include "lcd.h"

    Here's how I use my LCD class:

    [SOLVED]Closed: Re: puzzled with this transformer

    The input is 115VAC the output is 48VAC (24 - 0 - 24). I know the circuit uses about 40ma max. But I don't know the exact power rating. It just seems to me that the primary DC resistance of 1K is...

    [SOLVED]Closed: puzzled with this transformer

    Hello

    I have an MXR 117 phaser pedal that I was repairing. It plugs directly into mains and has a transformer (120V Primary - 24V center tapped secondary) on the board which is followed by a...

    Closed: Re: Can someone identify this resistor.

    Thanks. I agree but for the resistor second from the right there should not be a black band at the end either because there is no tolerance level defined for black. So why is one of the outer bands...

    Closed: Re: Can someone identify this resistor.

    That sounds good. I just noticed that the gap is wider.

    What do you think about the resister before that one? The gaps look the same to me.
    That one looks to be Brown Red Yellow Red Black =...

    Closed: Re: Can someone identify this resistor.

    I meant to say is it 825 or 10.5K?

    Grey - red - green - black - brown = 825 Ohms
    brown - black - green - red - Grey(or silver?) = 10.5K Ohms

    So how do you know what is the correct orientation?

    Closed: Can someone identify this resistor.

    Can someone identify the resistor with the grayish / silver band at the end?
    Would you say its a 500 Ohm or 825 Ohm?

    Yes I agree that's why I posted originally if you could help me find a schematic that would be great.
    I have searched everywhere and cannot find one for this.
    So if you can show me where to...

    Thanks You Andre!

    You Nailed it! I put a ceramic cap to in 1 fixed it. The voltage now remains at 18 regardless of load current.

    The circuit is currently on a Breadboard. I don't see an issue with making this work on a breadboard. I have done this on a breadboard successfully before.
    I suspect the chips are bad. I got...
  14. [SOLVED]Closed: Re: Boost converter using MC34063 - problem when Iout is lower than designed

    I already tried those options. I have doubled inductance to 200uH and also tried increasing capacitance. Same results.
    I'm starting to think the batch of MC34063 chips I have are bad.
  15. [SOLVED]Closed: Boost converter using MC34063 - problem when Iout is lower than designed

    Hello,

    I have used the MC34063 to build a circuit to output 18V 100ma from 12 V input and used an electronic load to test in constant current mode of 100ma.
    It is fine when my load draws 100ma...
