Hello,
I am trying to interface ADXL345 with CC2500 wireless module. I tried making connections of the respective pins of adxl345 accelerometer with cc2500 and read the values on the computer through arduino.
The basic scheme is as follows:
ADXL345 > CC2500 -| ))) (((|- CC2500 >...
I'm working on interfacing accelerometer with 89V51. so i need to convert the values through ADC.
Can anybody suggest how do i generate clock through microcontroller and give it to ADC?
And if anyone has worked on interfacing 89V51 with accelerometer?
Thank you for the reply amol. Actually i already have a transmitter n receiver as mentioned earlier and i don't want to make the transmitter circuit complex as it would be mounted on the palm.
I have not used PIC yet so would prefer 89v51. The link provided was quite informative. Would try...
I tried implementing to split the X and Y outputs using two comparator IC [LM358]. But the output wasn't satisfactory. Can anyone suggest some other circuit to get the output as i had mentioned before. Do i need to use ADC?
Thank you for the reply Santosh.
Even i had thought of using a comparator but i'm not able to figure out how do i split the linear output from accelerometer [i.e. 0.8V to 2.8V] into two [i.e. from 0.8V to 1.65V and 1.66V to 2.8 V].
I need a circuit which can split the outputs X and Y into...
Hello everyone,
i have a wireless robot with 434 mhz frequency and HT12E and HT 12D as encoder and decoder respectively.
i want to control my robot using 2 axes accelerometer in forward, reverse, left and right directions.
I'm facing problem interfacing accelerometer with this circuit as i just...
I'm making a project to get temperature wirelessly using XBee series 1.
I want to attach the other XBee directly to my PC without any microcontroller and get the LM35 temperature sensor data. I would use the XBee's ADC to acquire data.
One more thing the sensor is mounted on a robot and i even...
Hello,
Can i get few details about zigbee or rather xbee wireless module(wire antenna). Also i want to know does it operate on different channels if i want to use 2 transreceivers. First I'm trying to build two wireless robot that can be controlled using xbee simultaneously. Is this possible? If...
I am working on Tx Rx based on HT640 and HT648 on 434Mhz with ASK Module. I am in search of a good compatible antenna for the same because I always face problem of range while operaing it. Please suggest me something!!! Thank you...
Hello friends,
I'm performing an experiment to get current temperature and light intensity of a room.
For this i'm using p89v51rd2 microcontroller, adc 0808, LDR and LM34.
I have few doubts:
1. Do i need to connect LM34 to an amplifier and then give that to adc or can i directly connect it...
hello sir,
i am new to zigbee. actually i want my two 89c51rd2 robots to communicate wirelesly . so can you suggest me any zigbee module suitable for my application.
it should be easily available.
can anyone can tell me that how to interface zigbee module with microcontroller 89c51rd2 & what software i will require for this? do we program zigbee module also? plz reply soon
Thank you for your response but i use an external ADC 0808 and then give those inputs to microcontroller.
Please if anyone can help regarding coding of the same in keil c compiler.
