Can you please tell me how many PWM, ADC and timers do we use or need for TC and RX code for the '433 MHz RF module with Arduino Tutorial 1 '? And which instruction from the code is for a timer usage, which one for pwm usage and which one for adc usage? I want to make shure because I am new with arduino and microcontrollers. Best regards. SOURCE: rf tech 433 mhz I had the same problem and finally found my manual. Here's what to do, everyone! Take back panel off the sending unit, where the three batteries are, by unscrewing the 4 phillips head screws (assuming you, like I, had put the screws back in after installing new batteries). You will see a little gray button in a hole above where the batteries are.
rc-switch has built-in functions that sends codewords for certain natively supported devices – so If you have one of these devices (I don’t) you may be able to skip this step.
Open the rc-switch “ReceiveDemo_Advanced” example sketch. Upload it and open the serial monitor. Hold your remote near your receiver module and press a button. The Arduino should decode the signal and print the results in the serial monitor. This is what I got for my remote-controlled mains switch when I press the button to turn channel 5 on:
The LX2262A-R4 uses a 12 tri-state bit codeword comprising 8 address bits followed by 4 data bits. For the tri-state codeword above – 011000001000 - the address is 01100000 (channel 5) and the data/command is 1000 (turn on).
My mains switches can have up to 8 addresses with a separate on and off command for each. By pressing every button and decoding the signals I worked out the codes for all the addresses and commands:
I suspect the address codewords will be the same for all devices of the same make & model – if anyone can confirm this please let me know.
The EV1527 chipset in my garage door remote uses a 24-bit codeword comprising 20 address bits followed by 4 data bits. The codes I got from my garage door remote are:
