I think Raspberry or Arduino would make things easier. This link points how to do it using Pic32, with usefull sublinks:

Mitra, thank you so much for your information. I got it perfectly, the voltage drop makes sense now. In fact, If i use 4V it doesn't turn on. Hobby, the current keeps on 450mA and twice 850mA for a quarter of a second (peeks). Maybe more current is being hide from the desk power supply because...
Ok, Susan did a big point. If you need to handle the picture data, I would recommend you to not use PIC, this task may be hard even for Arduino Controllers. I think this is the case for a Raspberry that has built-in camera and you will find no difficulty to make it black and white, and upload...
Hi Ranbeer. I'm an electronic newbie but I know pic. If I had to do that, I would isolate the camera button "trigger voltage", activate it using a pic port (bit set) with a resistor (maybe a capacitor? I'm learning about capacitors so I don't have any idea). Your doubt is about pic programming?
Guys, excuse me the delay to answer. Ads, the original wall supply is 5V but plugging it to the external power jack seems to have no effect. I believe the jack is broken.
These are the different behaviors by power supply and voltage (at the battery wires):
Simple 5V Wall Supply (1A?): Tablet...
That's right Klaus, this delay will give the "software" the return of processing after the chosen period. You set the frequency using setPwmFrequency, do your stuff and set delayMicroseconds, so the next line after delayMicroseconds will be executed after those microseconds for you to on-off or...
Wow, thanks Mitra but capacitors and inductors are far away from my acknowledgments. I believe my wall jack cannot handle 1A even saying 2A on the specifications. The diode tests I did with a true "table" DC power supply and it worked perfectly at 4.2 V. But when I switched to 5v with 1 and 2...
The battery is dead but I don't care so much because my intention is to use the tablet as an Arduino compiler and upload only. For me it's ok to use a wall power source.
I know the tablet works fine with a 4.2 v on the batteries wire because I tested it using a DC power supply. I noticed peeks...
If I understood, it's not a problem for Arduino. You need two commands:
1) setPwmFrquency(pin, divider)
2) DelayMicroseconds(value_here)
Arduino does it's magic.
Thanks Audioguru, I didn't know it was so dangerous. But I removed completely the battery, it's dead. I'm only using it's wires because external jack doesn't work either.
Thank you Klaus.
Yes, I = 0.8 on a max peek.
Using the DC power supply (4.2v with 2A max) I got readings from 0.46 to 0.8 A. This 0.8 A current seems to occur twice in a fraction of a second, most time is about 0.46A.
I will try this 1N4003. Thanks!
Rosty, I never used this model but the message says you don't have a connection to send these commands. Usually you need to "start network", maybe "Acquire client resource" commands before send and receive commands.
I'm newbie with electronics but I did some projects with Arduino. I may be wrong but seems to me you need a transistor. Using PWM to the base you got the current you want. Please someone tell me if I'm wrong.
Mitra is right, a code would help. A checklist for this subject would be:
- Make sure you changed port number on both commands (pinMode and digitalWrite).
- Make sure you have the correct driver for your Arduino version
- Check Arduino console for errors and warnings. Roll up the console...
Arduino is very easy to use and cheap compared to Raspberry. Arduino is a microcontroller while Raspberry is a different computer architecture.
For this project you will need an Arduino Uno, a Relay Shield and a Wifi shield. The relay shield is ready to use, just set the port and...
