The hardware of the SX126x chips can be designed to use either an internalLDOor an internalDCDC converter. The DCDC converter provides better current savings and will be used in most modules. If there are problems to get the SX126x to work, check which HW configuration is used and setUSE...
Current date and time (time_t) Example time_t myTime = myRTC.get(); set(time_t t) Description Sets the RTC date and time to the given time_t value. Clears the oscillator stop flag (OSF) bit in the control/status register. See the oscStopped() function and also the DS323x data...
This Processing sketch creates a file (using the current date and time as the filename) in the same directory as the Processing sketch. Messages received from Arduino are added to the file. Pressing any key saves the file and exits the program: /* * ReceiveMultipleFieldsBinaryToFile_P * ...
We are committed to meet you, IoT developers, where you are, and a significant number of you happen to use the Arduino IDE. We're making the experience better than ever by releasing a first-class int...
R=(supply voltage – LED Voltage) / LED current Or just use a 330 Ohm resistor, which is what I did. Why? Because it was laying in the box, and I know that in general it will work. 360 ohms is likely the correct value, or this sensor may have internal resistors, but since...
Current response time measurement in cognitive science relies heavily on measuring latencies of key presses on standard keyboards. Although our Study 4 showed that the precision of such measurements could be acceptable, this hinges immensely on the particular keyboard and paradigm. Furthermore, key pres...
First impressions of the Arduino/Intel-hybrid Galileo board - an x86 Arduino! - a small example project, and our likes and dislikes.
The ATmega328P used in an Arduino Nano and uno has a 10-bit ADC. This are known to most as analog pins. 10-bits means there are 1024 values it can represent from 0V to 5V (5V being the default voltage reference). When the ADC pins are used with voltage and current sensors design...
