Driving circuit schematic
The driving circuit depicted in Figure 18-12 consists of a connection between the driving portion, the microcontroller, and the air conditioning operation components of the bridge. The microcontroller's digital signal levels from ports P4.0 to P4.3 (approximately 12 feet) and...
High Resolution Digital Weigh-scale Design Using Z8 Encore! ?® Microcontrollers
The SP6691 circuit is designed to provide a high output voltage using a lower voltage boost regulator by incorporating a charge pump circuit. This configuration can convert a standard 30V boost regulator into a 60V boost regulator if necessary. Testing...
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...
Secured room access system
Security is a primary concern in daily life, and an access control system is a crucial component of a security framework. The microcontroller-based digital lock described here is an access control system that permits only authorized individuals to enter a...
Multitasking Pins circuit
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 the work of several. It was noted that...
A poormans oscilloscope
The oscilloscope remains one of the most essential measurement tools for electronic engineers. With the introduction of reasonably priced USB oscilloscopes, this instrument has become accessible to a wider audience. Twenty-five years ago, however, a quality oscilloscope was an expensive...
Miniature Real-time Controller
This is my long history the device that controls my home's night light, air-conditioner, etc. The device is a Miniature Real-time Controller. The circuit uses only three chips, a 89C2051, DS275 (or MAX232), and 74LS07 open collector driver. The scheduler...
delay
This article outlines the construction of a simple microcontroller-based delay circuit designed for photographic applications, such as drop or high-speed photography. It is capable of controlling the trigger lag for cameras and flash units, generating periodic trigger pulses, or managing...
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...
