This is required knowledge for every Arduino experimenter as they titled one of their most popular albums OK Computer and you have to love that. This has nothing whatsoever to do with RF modules but I thought I would mention it! The RadioHead that we are going to talk about is a code ...
At this point, you need a bit of care and organization. If using Windows, you will need two separate instances of the Arduino IDE running on your computer with different ports / COM numbers. You need to start each of them from the Start button. (Do not try to get the second one by ...
Arduino-Based Three-Phase Inverter Using Power MOSFET for Application in Microgrid Systemsdoi:10.18178/ijeetc.10.6.416-424Imran ChowdhurySaroar HossainNiloy Kumar DasMd Mahmudul Hasan
If this circuit is run without connecting an inductor, then there are high chances of damaging the mosfet due to high voltage spikes on terminal of mosfet. To prevent mosfet from thesehigh voltage spikesit is connected as shown in figure since when mosfet is on it stores energy and when mos...
The method of PWM is explained here; consider a simple circuit as shown in figure. This tutorial uses the L293D IC, we have also built a DC motor speed controller using MOSFET. You can also check that out if you are intrested. If the button is pressed if the figure, then the motor...
5V to 3.3V Level Converter using MOSFET The5V to 3.3V bi-directional logic level convertercircuitcan be seen in the below image - As you can see we have to provide a constant voltage of 5V and 3.3V to the resistors R1 and R2. The pinsLow_side_Logic_InputandHigh_Side_Logic_Inputcan...
Anyway, I'm still waiting for ordered logic level shifters based on BSS138, but I do not like this design as mentioned above n-channel mosfet failure could be disaster in some worst case scenarios For the moment I end up with slightly modified my idea of using 3.3Vz Zener diode...
electronic stuff as a hobby Cosmic Pixels, part 1. 5 Replies Spark Chamber in CERN’s permanent exhibition “Microcosm”. Since the first time I saw the spark chamber at the CERN exhibition nearly 20 years ago, I’ve been fascinated by how particle trajectories are directly visible between th...
I start to make a support as well. A simple aluminium plate with two 3D printed legs. I add several slots in order to choose the inclination. Coding I’m using an ESP32, with the arduino framework, and the Platform.io IDE. The nice thing is I could extends the AdafruitGFX lib. So...
