Problem is solved now. I am converting 5V to 3.3V now.
New problem is I am able to program Atmega328P but not able print the data on serial monitor through FTDI. Same code with FTDI is working on other hardware PCB but not with my PCB.
Hi All
I have designed a circuit but. I have tested 12V to 5V supply, it is working correctly but 12V to 3.3V is not converting and ASM1117 has got burnt. I am not able to identify the issue. Kindly help me in this.
HI Sir
My cabinet drawer is made up of acrylic and small in size. USB power banks are heavy for this.
For that I need Battery based power supply which should be compact
I am using 5V 1A Push pull solenoid for lock
Actually I have a box (size is nearly equal to a cabinet drawer) which will be locked automatically through solenoid.
Box is small and there is no much space to keep large design there.
For that I need a small battery with charging module.
Hi Sir
I need compact design which is light in weight and small in size.
I have searched on internet for rechargeable 5V battery but didn't find a solution.
There are mostly 3.6V,7.4V,11.1V rechargeable battery solutions available.
Hi All
I am using 5V push pull solenoid for my project and drive this solenoid through transistor which is connected to Arduino.
I want to give 5V power supply through rechargeable battery with USB charging also.
Is there any solution available and anyone knows about this?
I am using SMPS for both the supplies.
Output of SMPS is +5V,10A.
My question was what type of cable should we use for connecting power through SMPS for RPI and display.
Connection of MAX232 to RPI
RPI-----------------------------> MAX232
+5V-----------------------------> +5V...
We are using 10.1 inch touch screen display which is connected to RPI 3 model B through HDMI and Touch USB cable.
And MAX232 is connected to Raspberry Pi for serial communication.
We use these components for vending Machines and display is used for runnng app.
Hi
I want to use SMPS for Raspberry Pi 3 Model B and display but we need type B usb cable for supply.
How can I customize USB cable for it?
I have cut the one USB cable and there is 4 wires.
1. GND
2. +5V
3. Data+
4. Data-
I have connected GND to the GND of SMPS and +5V to the 5V of SMPS...
Yes I have tried but no success.
Same issue.
I have tested the motors by removing capacitor.
Sometimes motor rotates 100 rotation perfectly in which it took 1 extra round out of 100. (1 % error rate)
and sometimes motor gives continuously extra round with one 360 degree rotation. (70-80 %...
1. No direct supply on Motor. I have another Microcontroller board which has row(0V) and Columns(12V). Microcontroller gives the command on the row and column to operate a particular Motor.
2. I am using 2 diodes in my circuit and
Yes you are right Motor stop with the contacts in mid position...
Actually I have another Motor which works with different vending Machine and the top diagram which have a resistor is this motor diagram
I want my motor to work exactly same but my motor circuit was different so I decided to make it like that. So I added the resistor and remove the capacitor...
