  1. Circuits Arduino Supply Microcontrollers Usage Microchip ATtiny10 Attiny13 ATtiny24 ATtiny25 ATtiny44 ATtiny45 ATtiny84 ATtiny85
    The ATtiny45/85 USB Phone Charge Guard controls and monitors the charging of phones and other devices (Figure 1). Voltage, current, power and energy are constantly measured via the INA219 and compared with the user limit values. It cuts off the ...

    Because the 8-pin ATtinys only have a few GPIO pins available, they are usually operated without an external clock. The internal oscillator does a good job in most applications, but when it comes to precise timing, its 10% accuracy is often ...

  1. The simple ADC in Figure 1 is perfect for getting analog signals into a purely digital microcontroller. Using just five surface-mount parts, you can assemble it for less than 50 cents (1000), which is approximately half the cost of a ...

  2. Most microprocessors have some type of hardware watchdog that can be used to reset the microprocessor and the surrounding hardware to a known state if firmware inadvertently stops executing code. But it may be advantageous to record the ...

  3. Driving multiple LEDs with one microprocessor GPIO pin is a well-known technique. Typically, designs perform this task by issuing pulse widths and clocks of differing durations and employing multiple RC networks to distinguish between them. The ...

  4. This Design Idea describes an enhancement to a previous one ( Reference 1 ). The circuit in Figure 1 uses a normally open SPST pushbutton switch, S 1 , instead of the SPDT switch that the original design required. You can use a membrane switch to ...

  5. The 4- to 20-mA current loop is ubiquitous in the world of controls in manufacturing plants. Discrete logic, microprocessors, and microcontrollers easily cover the digital portions of control schemes, such as limit switches, pushbuttons, and signal ...

  6. When a processor-controlled device must operate reliably, designers often choose to periodically reset the processor rather than rely on a watchdog configuration. In low-power systems, this periodic-reset circuit can consume a large part of the ...
