Re: 74HC595 shift register

Hi,

If you are working on 74HC595 then you should have a look at Arduino 74HC595 Interfacing: Increase Output Pins and download its Proteus Simulation so that you could have a better understanding of this shift register.

Thanks.

Re: Motor control

Hi,

You should have a look at L298 Motor Driver. It's a dual motor driver and can control both direction as well as speed. You should also test it out in Proteus Simulation.

Thanks.

Re: Controling the temperature of an oven

Hi,

It's not that difficult, you just need to place a check in multiples of 3 , and after 3 hours you can increment a variable 1 time. If you could share your code then I can better help you out.

Thanks.

Re: Help with OPAMPS ?

Hey guys, I'm trying to make a galvanic skin response sensor to get some biometric data. I stumbled upon this schematic: http://web.media.mit.edu/~msung/VitaMon/vitamonschematics.htm It is using a OPA4366ea amp. I'm wondering if I can use something else that will do the job... I have LM741cn - just...

Re: VS1103 Breakout Board

Hi JMC1965, Thank You for the informations. I think to use an external 3.3 volt regulator too ( I have some LT1584 ). For audio output I am going to use an OPA like LM358 that works fine with low voltage. Maybe a good choice with AA batteries. Regards Antaeus Hi, LM358 is quite a nice option. If yo...

Re: Attiny ir relay

First of all, test a simple code on your Attiny 85 to check whether its working or not. If it's not working then you are standing at 0 and If it's working then you need to check the Arduino Nano Pinout and Attiny 85 Pinout . I have worked on Arduino UNO and they have different Pinouts if you are usi...

capacitor of at least 100 ohm at +3.3V and GND.
Make that 100 microfarads...
Hahaha thanks for mentioning and sorry for the mistake ...... yeah its 100 uF capacitor and you should also try 1000 uF capacitor if the first one doesn't work.

Re: Waste Tank Discharge Project

First of all I wasn't spamming the forum. Secondly, I have suggested a really good solution, he said that he wants some solution related to controller / switch control. So, I just presented an embedded solution. The one you provided is good but not much flexible. Although, if you shake hands with em...

Re: pic16f628 UART

really strange,i used a Parallax USB to Serial before and is wasn't working. With the FTDI basic breakout it is working now. The only i have now is that the breadboard is really sensitive, when I touch a wire the terminal is flipping, I will figure it out on the internet, maby put caps and resistor...

Re: Newbie to PIC - distance sensing and chip selection

Ah, that I wasn't aware of. I though Ardunio processors were all self-contained on their own PCB boards. This may require further investigation! :) Thanks for that. Rick Yeah you can easily get the microcontroller out of Arduino UNO and can use to alone. But you have to design its basic circuit. Ar...

Re: nRF24L01 Transceivers Not Working

Hi, I have worked on these RF modules NRF24L01 and I must say that I really admire them. Because they are quite easy to use and very cheap. I think you have done everything correctly and I would suggest you to place a capacitor of at least 100 ohm at +3.3V and GND. Your RF Module must be powered up ...
