Training Boxing timer schematic
A timer is being developed for circuit training or boxing training. The timer does not require any external input, except for a reset function. The project can be simplified using a microcontroller, such as the PIC12F635, which is cost-effective at...
Inexpensive_frequency_counter_tachometer
This circuit illustrates the configuration of an ICM7217 and an ICM7555 designed as a basic frequency counter. The connections between the ICM7217 and a common-cathode LED display are depicted in Figure 12-18. Calibration of the frequency counter is accomplished using...
Mains Frequency Monitor circuit and explanation
This is a simple frequency counter designed to monitor the 240VAC mains supply. It has a frequency range of 0-999Hz, making it suitable for use with 400Hz equipment as well. Standard TTL/CMOS logic is utilized for the counters and display...
GSM Remote Control 2 IN and 2 OUT Part 2 Schematic
The control of the system is managed by a Microchip PIC18F46K20-I/PT microcontroller, which is programmed with firmware to oversee the activity of the GSM/GPRS module, monitor the logic conditions of two opto-isolated inputs, and send commands to two relays within...
Interpolating Scanner Circuit
This design is for an interpolating scanner, a circuit featuring multiple signal inputs, a control voltage input, and a signal output. The output selectively transitions between inputs, smoothly fading from one to the next as the control voltage increases. A...
Frequency Counter Circuit using Micro Controller
A simple frequency meter or frequency counter circuit featuring an LCD display and an AVR microcontroller. This includes a DIY schematic circuit diagram and embedded C code.
The frequency meter circuit is designed to measure the frequency of input signals and...
Microcontroller-based automatic night light circuit
While discussing an all-linear automatic night light circuit, it was mentioned that an MCU-based Automatic Night Light Controller (ANLC) was being tested. The firmware has been tweaked since then. Recently, the sensor was installed outdoors and connected to control 220VAC...
Multitasking Pins
It is entirely logical that low-cost miniature microcontrollers have fewer pins than their larger counterparts, sometimes too few. Consideration has been given to how to economize on pins by making them perform multiple functions. One approach is to exploit the...
Frequency Counter
An individual sought to utilize a soldering iron to construct a frequency counter, a device that was previously absent in their lab. The schematic for the frequency counter was created using OrCAD PSpice, but the design files have since been...
