1Hz to 1MHz Frequency Meter with Digital Display
The circuit was designed to create a low-cost frequency meter that will cover the range of 1 Hz to 1 MHz with a digital indication using three 7-segment displays.
The frequency meter circuit operates by measuring the frequency of an input...
up down counter circuit
This circuit diagram illustrates a simple up/down counter suitable for various applications. It utilizes the CD40110BE IC, a CMOS decade up/down counter. Common cathode seven-segment displays are connected to the outputs of each IC. The display connected to IC1 shows...
Cheap frequency meter by CA3130
This inexpensive frequency meter circuit is suitable for general use in small laboratories. It is cost-effective, easy to construct, and sufficiently reliable for most electronics enthusiasts. The frequency can be directly read from the meter, with a measurement range from...
1300 Mhz Frequency meter with prescaler
Having found a u664b prescaler chip (Telefunken) from an old TV tuner, I decided to build a valid frequency counter using PIC16F84. The prescaler I use is able to divide by 64 every frequency from 30 to 1300 MHz. The...
Blanket internal measurement circuit disconnection
The internal disconnection circuit for a blanket operates on the principle of induction. It includes a wire approximately 2 cm in length that senses the proximity of a charged mains power source. When the sensing wire is close to the...
Winding electronic counter 2
The electronic counter of the winding machine utilizes an LED digital display to indicate the number of turns of the wound coil, with a maximum counting capacity of 9900 turns. The operational principle of the winding machine circuit consists of...
Debounced Counter Made From Off-The-Shelf Chips
The true utility of the SR latch is evident during transitions of the input switch. Assume that the input switch is of the break-before-make type and starts in the up position. When the switch is up, the input values are...
Frequency Meter and Pulse Generator with AT902313
Power input is to a 7805 5 volt regulator. A pair of LEDs is connected between the 5 volt supply and ground, with current limiting resistors in series and one pin on the AT90S2313 shunts the current through one LED...
Divide-By-Odd-Number Counter
This circuit symmetrically divides an input by virtually any odd number. The circuit contains n + 1 clocks to achieve the desired divisor. By selecting the proper n, which is the decoded output of the 74LS161 counter, divisors from 3...
