Re: embedded systems
You can make a weather sensor like a rain meter or a temperature measurement system. Or make a small robot-like vehicle which can sense objects and take necessary decisions. The options are endless.. It all depends on what you want to do in the first place and your resources.
difference between spi and uart
USArt refers to the hardware part, spi is a 3 wire protocol. Several Microcontrollers have USARTs built in. Some have a spi interface also. spi is a Philips based interface.
Hope this is of help
Hello,
One can use a bridge circuit,or an instrumentation amplifier. The choice will depend upon the common mode voltage.Also one can use an appropriate filter.
Hope it has been of some help. One needs specific details of your circuit for further help.
thermocouple temperature display projects
Hi,
You have to be specific about the temperature range, the type of sensor and the accuracy level required. If it is just 0-150 degrees, then an LM35 or a similar IC would suffice. For higher temperatures one has to use a thermocouple or a RTD. The...
