hello everyone
In mid-November, I have designed a shield based on arduino.I have wrote two posts in DIY Area. have to debug a week.However, it does not work.The OLED display and bluetooth is ok.
Here is my sch,
Here is my pcb
You can see in my schematic，I use IIC to...
I had received a lot of advice.They point out my mistakes to help me improve.I am very grateful to them.After a modification over time, I sent my gerber files Smart-prototyping and production. I changed a lot, I was going to use PCF2129 replacement DS1307, but PCF2129 is expensive so I had to...
Most of the Bluetooth module is SMD. But any course you can find some use the adapter plate module, they can be used directly on the through-holes.I recommend HM10 Bluetooth, you can find in ebay.
Well, low-cost chips and cheap labor power to make more and more goods commoditization. Maybe later I'll buy some components from India or something like that. Before this, I have been buying components and PCB service from Shenzhen.
hello everyone
I want to make an arduino shield with display, also I want to integrate more functions. But now I have no more good ideas. Here are some simple function I want to achieve.
First is the display, not the kind of big, ugly 1602 or 12864, it must be small, clear.
So I chose 0.96 inch...
hello everyone
Today, this is my first time post here, rather than replies. I am very happy to come to this forum to learn more knowledge of electronics.I share a project I've ever done, an AVR/51 ISP programmer, Maybe it is simple, I think there must be someone who need it. PCB and...
hi
I've seen POV mounted on a bicycle, riding a bicycle at night when very dazzling. My friend who live in shenzhen told me, the cost is only $ 7.I really don’t know why.
Thanks
Hi
Here is a nokia 5110 LCD library based on arduino, as far as I know, nokia3310 and 5110 are mostly the same. Maybe helpful.You can very simply transfer it to PIC.Good luck for you.
Thanks

If you want to get a higher speed, I suggest you lengthening the appropriate distance between the sensor and the car,Using more sensors that can help you better access path.
Thanks
