This control circuit for microcontrollers uses a pressure switch to prevent peal. Equivalent components can be tried out.
The proposed circuit generates signals in the range between 9 kHz and more than 44 kHz, which, it is...
This circuit uses currently uncommon components, including the 10.7 MHz (FI) filter. This circuit was...
This small power supply for low currents (5mA) is suitable for power low-power TTL experimental circuits....
