Complete an Arduino project that uses 2 Arduino micro-controllers that communicate via RF antennas to turn an LED strip on/off. One arduino will be a transmitter that uses an RC522 RFID reader to read an RFID ring and send a signal to the Arduino receiver that will turn the lights on an...
We choseArduino hardware, as it is open source, has a huge support community, and the hardware and software are easy to use. It is also a very inexpensive introduction to do-it-yourself (DIY) electronics. Due to its small size and price, we used theArduino Nanofor this project. The pr...
Re: How to make a simple, noise free 5v->3.3v DC linear voltage regulator circuit? « Reply #2 on: March 19, 2024, 10:08:01 pm » Arduino Nano has maximum total current of no more than 200mA (and uses AMS1117), if I understand correctly.So 200-300mA would be the ballpark ...
The I/O pin names that are silkscreened on the Teensy can be used in the code but must be preceded with PIN_ (example PIN_B7). The code looks more "Arduino-ish" if you use I/O numbers. See the schematic above for translating the silkscreen pin names to Arduino I/O numbers. ...
The issue though is that at 0 amps the CS output is NOT zero volt, instead it is 26mV. Hence I need to "subtract" 26mV from this CS output voltage. What would be the simplest way to do this (without using fancy gizmos like an Arduino, just regular "jelly bean" components)?
In the boards manager, click Install on the Arduino SAM Boards. Once this finishes installing, scroll down to the bottom of the boards manager and install RFduino Boards. After both board packages have installed, you should see the RFDuino board in the Board section of the Tools menu. ...
The Arduino will measure the voltage at a point between the thermistor and a known resistor. This is known as a voltage divider. The equation for a voltage divider is: In terms of the voltage divider in a thermistor circuit, the variables in the equation above are: ...
All these new features would require a lot of additional circuitry, and a simple piece of perf-board would not cut it. This required a PCB, which I designed in EagleCAD. I began by laying out the connections with their schematic editor. Then I moved onto making the actual board and trac...
