Happy to be back on Amateur Radio on International Space Station after ‘Servicing’ my Moxon Yagi. Being 10 am on a working day, it was a ‘lonely pass’!
See the A4988 driver Stepper Motor Driver for NEMA 17 Stepper Motor. Driver is needed for controlling NEMA 17 using microcontrollers like Arduino and Raspberry Pi Pico.
RG316 is a small diameter coaxial cable with silver-covered copper-clad steel stranded inner conductor. That means the innermost layer is steel, providing strength, followed by copper clad next
This is my new NEMA 17 stepper motor which I purchased from a local shop. NEMA stands for National Electrical Manufacturers Association, which standardized motor sizes using certain
Here I am demonstrating the use of 5V relay module to switch a 12V/1.5A automotive bulb using the digital output of Arduino Nano. Same principle can be used
ESP8266 is a microcontroller which integrates a Tensilica 32-bit processor. It is WiFi enabled and is a popular choice for the use of Internet of Things (IoT). ESP8266
Some of you might remember Franklin’s Kite, the historic experiment conducted by Benjamin Franklin in 1752. Using a kite with a wet hemp string coming down to a
Few days back I had posted about checking the WiFi signals from an ESP32 development board which I had bought recently. I never imagined that this is a
GPIO pins in microcontrollers like Arduino Nano are General Purpose Input/Output pins. They can be configured by software to act as either an input or an output. This
