How to make Simple 500KHz Oscilloscope with STM32 ( Arduino IDE )
https://maker.pro/stm32-nucleo/projects/how-to-make-simple-500mhz-oscilloscope-with-stm32-arduino-ide
DIY oscilloscope with STM32 Microcontroller which has better performances than Arduino and is also cheaper. With this instrument we can now observe the shape of signals with a frequency of up to 500KHz.
Arduino LCD Info panel for PC (LCD Smartie)
https://maker.pro/anduino/projects/arduino-lcd-info-panel-for-pc-lcd-smartie
This is a simple way to control 16x2 LCD Display via Windows PC software. For this purpose, we use an Arduino microcontroller, which in this case has the function of an interface between the Display and the USB port of the Computer.

ESP8266 Word Clock on 16x16 Led Matrix
https://maker.pro/anduino/projects/esp8266-word-clock-on-16x16-led-matrix
Word Clock is a special type of clock where the current time is highlighted within a set of words that can tell any possible time. This is very simple way to make such an interesting clock, where a ready-made led matrix is used as a display.
Simple STM32 Frequency meter from 1Hz to 30 MHz (Arduino IDE)
https://maker.pro/stm32-nucleo/projects/simple-stm32-frequency-meter-from-1hz-to-30-mhz-arduino-ide
This frequency meter uses an inexpensive STM32 microcontroller and this time, thanks to his better perfomances of the MCU, the frequency range is from 0 to 30 MHz, and therefore it is ideal for use in HF radio devices.
