i am having a CC2541 (HM10 module) and arduino, i have seen some ad like when the person enter into a shopping complex a ad pop up likely 20% off on cloths in ikea store. my question is can cc2541 work as ble for advertisement like a store beacon? can it shows something without app as my friend...
i am working on some project and i got stuck at a point .
i have a component that is 5 pin sot smd.
my guess is, op-amp. But the question is why Vs pin of op-amp is connected to ground with some resistance.
needed help in finding component and value of resistance.
as i have searched on...
i am using as you said, solenoid valve with 24v unregulated supply
and tested this before posting thread:- lm317 ==> 7805==> micro controller. now lm317 and 7805 also heat.
conclusion:- total heat of 7805 now divided into lm317 and 7805.
i am using TIP122 and 817 opto-coupler to drive...
hi
i working on some project and facing problem with all regulator(lm317, lm2576 5v, 7805)
i am using AT89s52 + HC05(Bluetooth module) + solenoid valve
my task is simple on/off solenoid valve via bluetooth through android app.
micro-controller works upon 5v and solenoid valve operates on...
I am using PIC16F877A with the Bluetooth module (HC-05) in UART . problem is that when i get a char from UART and send it to PORTB then its shows some value in 0 and 1.
but i wanted to check, what char it is then its not working. :x
i have tried as a char like
if RCREG=='A' but its not...
thanks IanP for your reply. i choose 89s52 just for making simple, but if don't work on that, i will try using PIC18f4550. can PIC do this work ??
and if know how induction cooker coil will work with PIC and what circuits and schematics are used than just let me know..
hi
i want to interfacing induction cooker coil with the 89s52. i have a circuit of induction cooker(2200 watt).The circuit have many component like igbt,cooling fan and more .As i have searched for igbt and induction cooker circuit , i found that its works on L-C concept. i am not good at these...
finally i got it...
i needed one more help..
when count some event like how much time switch is pressed, then the value of counter have to be shown on lcd. then we pass it with adding +48. but still it give the garbage value..
here is my code and bit map if connections...
this code will work on the TX side...
on RX side what algo is required ??
- - - Updated - - -
in TX side i had an extra switch,which is connected to TX controller .when this switch is pressed then it will send the data .
for differentiating upper and lower nibbles i think 10 ms gap is enough.
yeah, its typed wrong by me sorry..
can i get any type of code in embedded c which convert 8 bit to 4 bit & again decode it from 4 bit to 8 bit ..
actually i m counting simple event like how much times switch is pressed on TX side and on RX side i want to display this values on lcd ...
TX...
hiii everyone..
i am trying to send 8 bit data through rf module(433 mhz)
but first i have to convert 8 bit data convert into 4 bit using 8051(AT89S52) through embedded c
i want the same data in receiver side as i send from transmitter side.
can somebody help me for the algorithm of this...
