salam,,, thanks for concern i need to sense temperaure ,pressure the timers used in my country almost mechanical timers(cam) so the snsors all are high power sensors (220 V) pressure(daiphragm) ,solenoid , and heater those all are used to measure water level ,and allow water in and out ,and heat water respectively i need
one single PIC microcontroller is not enough. Overall you need an array of PIC's synchronized with each other in order to make it altogether work. The higher the frequency the better is it. Plus you need a large memory over 64-128kb attached in the chip. Idea seems great, francky must yeild inexpensive solution to the problem and becomes better
I use microcontrollers for a long time in low voltage (instrumentation and display) applications. But when I tried to make a washing machine controller, I was in a real problem. The microcontroller operartes some small relays to drive some 220 volt operated devices of the machine e.g. pump, heater, door lock, motor etc. but I found that one (...)
Hi everyone I need to control the washing machine using PIC microcontroller : The following are the design considerations to be followed: 1. Set the time using a DIP switch (maximum value is 99 seconds) 2. The setting values should be displayed on the seven segment display 3. The spin process should begin when the start button is pressed an
What microcontroller you use? What c compiler you use?
Yes Let us try What Are The Things You Are Trying To Do With Washin Machine And microcontroller?
Market forces, obviously. Just because you may have a need for a GHz micro-controller doesn't mean that the volume consumers of it (washing machines, car radios, etc..) need such a device. Would you invest millions making a GHz microcontroller for a sale of 1?
Hi guys, someone know about a decompiler for microcontroller's code like 16F84. Decompiler! Not Disassembler. Thanks for support
Hello, Does anyone know or have information about the possibility of doing an interface between a nokia cell phone and a microconttroller?? ... I've got an "old" nokia 5160 and i'd like to know if it's possible to use a microcontroller to send datas over the cell phone .. cheers, chak-mool
I am planning to build a microcontroller power supply. Should be symmetrical, 0-30V and adjustable current limit.. both voltage and current limit controlled via D/A converters.

Has anybody infos on interfacing usb cameras to microcontroller. I'm interested on the packet of data coming from the camera...... Thx
Generally overclocking a microcontroller doesn't generate a problem, until a certain percentage of course. The manufacturers guarantee what they have their parts tested for, although they can be quite conservative sometimes. The issue is though that what seems to work fine in the LAB is not guaranteed to work well in a product, over the compl
I search to buld project mobile robot with PIC or AT (ATMEL) microcontroller. Project have must hardware + software.

Hi - Looking for a pager module to interface to a microcontroller. End result is to be able to send commands to microcontroller by calling a pager phone number and entering codes. Good article here : Does anyone know of any others ? Thanks -
can any1 give me a circuit for capacitor discharge ignition using microcontroller. i had tried few circuit but it is not working properly. i found few pspice version also but no use can any1 give me working model of cdi sriram p.s: automotive electronics is a good field y dont we start for forum for automobiles
Hi - I didn't get any response over in the RF forum, so I though I would ask here ... Looking for a pager module to interface to a microcontroller. End result is to be able to send commands to microcontroller by calling a pager phone number and entering codes. Good article here :
This program uses an 8 bit DAC along with a 16F84 PIC microcontroller to generate a keyed sine wave. The 16F84 uses an RC clock which can be varied (with a suitable potentiometer) to allow a variable frequency control for the sine wave output. A key or keyer output can be connected to pin 1 of the PIC to control the tone output. h**p://www.qsl.n

I need to build a microcontroller network, i have tough to make it with CAN or RS-485. What do you think is the best protocol for make it, thanks Is there any other protocol better for make an emmbedded network?
Hi all We would like to give a microcontroller introduction at our radio club. We were thinking of either the PIC or 8051 micro as a start. The idea would be to give a short intro and then get into making a small development board and then get into the programming of the micro. The reason for choosing the micro's above are easy availabilit
