    DS1307 can not read and write time in arduino.

    Thank you, I've solved the problem. If no AP2306, DS1307 can work properly. I'm sure the problem is the level conversion circuit.

    My first shield back,Integrates a variety of sensors.

    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...

    arduino shield with magnetometer,clock,and OLED

    hi,mister T I ignored this important point.I will change it,I will add some capacitance to the module.Also, I would pull on the IIC bus resistor connected directly to the A4, A5 pin. No matter what the state of the switch, The IIC bus is always on the pull.After that, I will upload the new...

    arduino shield with magnetometer,clock,and OLED

    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...
