Frequency warning alarm
A low-frequency oscillator (Q1) modulates a high-frequency oscillator (Q2) along with its associated timing capacitor. The output frequency varies continuously.
The circuit comprises two primary components: the low-frequency oscillator (Q1) and the high-frequency oscillator (Q2). The low-frequency oscillator is responsible for...
water level controller circuit diagram
The circuit consists of a 555 timer IC configured as a multivibrator, which operates with two probes to measure the water level. When the capacitance between the probes indicates a high water level, the output from the 555 timer is...
Solid State Power Controller
The circuit is built around two 555 timer ICs, U1 and U2. U1 is configured as a variable duty cycle oscillator with a constant time period of approximately 0.1 seconds. The duty cycle can be adjusted from 0 to 100...
