Also, you might want to take a look at other compilation options and default values in 'code/espurna/config/general.h'. Building & Flashing the firmware First you will have to choose the right board and memory map. Here you have a list of the supported board types and the suggested confi...
However since sending is a serial task, you can use setSendPin() to switch the pin to send, thus emulating multiple sender. The receiver uses a special timer triggered function, which reads the digital IR signal value from one pin every 50 µs. So multiple IR receivers can only be use...
[mod]); // adjust the mask if we're not going to reach the end of this byte if(h < mod) mask &= (0XFF >> (mod - h)); switch(color) { case SSD1306_WHITE: *pBuf |= mask; break; case SSD1306_BLACK: *pBuf &= ~mask; break; case SSD1306_INVERSE: *pBuf ^= mask; ...
4.9. Sending the Value of Multiple Arduino Pins Problem You want to send groupsof binary bytes, integers, or long values from Arduino. For example, you may want to send the values of the digital and analog pins to Processing. Solution ...
In the case of a pull-down resistor (image 1), we connect one leg of the switch to 5v, and the other leg through a resistor (10kΩ in this case) to ground (0v). The leg with the resistor connected goes to the input pin on the Arduino. ...
switch a high voltage MOSFET using the driver. A MOSFET has a gate capacitance that you need to charge so that the MOSFET can turn on and discharge it to switch off, the more current you can provide to the gate the faster you switching on/off the MOSFET, that is why you use a ...
But I would like to send an analog value and an on / or switch command to a receiver. I have not yet succeeded. Have you already done something with it? It seems very nice to be able to read something from a greater distance and to switch than just to transfer text. I just have ...
