Embedded systems serve as the core of most electronics-based systems, enabling data access, processing, storage, and control. While some simple electronic circuits can be designed without a microprocessor or microcontroller, this approach is often economically impractical, except for basic passive...
Adaptor for 8 and 28 pin AVR
This adaptor lets me program 8 or 20 pin DIP devices using the In-System Programmer (ISP) described in Atmel's AVR910 application note. This circuit provides power and clocks for the part to be programmed and power to the ISP circuit....
PWM Motor Speed Controller
A pulse width modulator (PWM) is a device that may be used as an efficient light dimmer or DC motor speed controller. The circuit described here is for a general purpose device that can control DC devices which draw up...

The following circuit illustrates a simple stepper motor controller circuit diagram. This circuit is based on the 7404 integrated circuit. Features include suitable heat dissipation.
The simple stepper motor controller circuit utilizes the 7404 hex inverter IC to control the operation...
how to convert a 9v battery to 3.7v
A regulator circuit is needed for this DIY project. Familiarity with electronic components, circuitry, the use of a multitester, and a soldering iron is essential. The schematic diagram provided can accept an input voltage ranging from 6 to 24 volts...
avr Control 5V buzzer using mcu and a single 5 V power supply
A PB-12N23PW-05Q buzzer is being used with an ATmega 162 microcontroller. Direct connection to the microcontroller pin is not feasible due to the maximum sourcing capability of 20 mA as stated in the ATmega 162 datasheet, while the buzzer requires...
avr
Inspired by the work of Nanode and a recent Instructable, an AVR-based Ethernet board has been developed that can be programmed and utilized similarly to an Arduino. This straightforward design is based on the ATMega microcontroller and Microchip's ENC28J60 Ethernet...
PWM Lamp or Motor Controller
This design is intended as a dimmer for a 12V reading lamp, but it can also function as a motor speed controller for devices like drills. The circuit modulates the voltage supplied to the load, allowing for variable pulse width...
Analog PWM connection with FIG zps-101 interface
An AC-DC-AC circuit utilizes a power transistor as a switching device with analog control, as recommended in the wiring diagram of Figure 6-10. This circuit generates a voltage-controlled oscillator (VCO) using OCT and FCT, with RCT available for OCT delay....
