Re: Regarding WiFi Module
Hi
I have recently come across WIFI module by DIGI in same footprint as Zigbee modules. I was searching for something for my home automation project.
The advantage to me is that it can be used with Zigbee shields of Arduino. The whole setup with webserver(on Arduino)...
Hi
My 2 cents. It is good to start with self made programmer, but if you going to use Atmel AVR for long (as most get addicted to it), please invest in a good programmer. There is a good reason to it. When programming devices a lot of data is transfered and the data lines switch rapidly...
Hi
I have been using Arduino and various Atmel AVR uC for many years. Though the software part has very wide user group and is well supported, hardware design gets frustrating sometimes.To overcome some frustration, I have made a flexible Arduino compatible I/O board with 8 I/O. Yes you can...
Hi
We have new Arduino compatible Boards and shields available in New Delhi India. These are build from high quality double sided PCB with through hole. These can be purchased through cash payment in New Delhi or through our online shop for rest of the customers in India. The **broken link...
Re: USB Arduino Atmega328 in India
Hi
We now have new boards with bigger AVRs.
1) Atmega1284p with AVRDUDE bootloader. This board is compact and accepts RS232 or TTL serial. It also comes with JTAG interface. This board has been tested to work with Arduino (after modification).
During...

True Millwood the initialisation is not correct in the C code.
Hi Raj
Please see page 45 of Hitachi Datasheet. the first instruction 0x38 (000011****) must stay for significant time (use delay between instructions) for the LCD to enter into initialisation mode and start accepting your...
Hi
0x0F is ok and yes it should have also shown in Proteus as blank LCD. I am going through your schematic and code. The first thing I noticed is your RESET does not have pull-up. If true please add a 10k to VCC.
Let me know the progress. I will revert back if I find something in the code.
Thanks
Hi
If you have used the code as it is from hitachi or other datasheet, then I think you have not turned on the display (last or second last line in the datasheet).
please understand see this line again in the datasheet.

If you have squares and then clean display then...
Re: about line follower
Hi
For a line follower it can be done in many ways. One of it is to connect the photodiodes to digital outputs through 500ohm resistor. The photoreceivers are connected together and biased through high value (~63k) pull up resistor. The common (between photoreceivers...
Hi
Had faced similar problem when I was trying to connect PC RS232 to a device with Infrared communication requiring infrared LED's to be powered from RS232 port. Basically all the handshaking (HS) signals individually will be connected to a positive and a negative capacitors acting as power...
Hi
