If you use a microcontroller to detect a key closure, checking the states of (x+y) lines requires an equal number of I/O pins. Occupying only one free I/O pin, the circuit communicates with a microcontroller...

Using a PN-junction diode for temperature measurement usually depends on its 2 mV/K temperature coefficient. Less well-known is the fact that the reverse current of a PN-junction diode shows a good exponential dependency over temperature...

Why not take advantage of the micro-controller included in many systems these days? This design uses microcontroller feedback to produce a –50-V, 1-W power supply...

TinyLoad is a simple electronic constant current dummy load. The ATtiny measures voltage, current and temperature of the heat sink, calculates power, energy and battery capacity, controls the fan and displays all relevant data on the OLED...

The ATtiny45/85 USB Phone Charge Guard controls and monitors the charging of phones and other devices. Voltage, current, power and energy are constantly measured...

Also called the ThermoPen, the goal of this project was to create a portable thermometer usable for precise uses case...

PragmatIC Semiconductor’s recent announcement about developing a flexible version of the 6502 processor takes tech history buffs on the road to nostalgia...

Texas Instruments introduced a new high-performance microcontroller portfolio that advances real-time control, networking and analytics applications at the edge. With new Sitara AM2x MCUs, engineers can achieve 10 times the computing capability of traditional...

TinyCharger is an ATtiny25/45/85-based, single-cell Li-ion battery charger with selectable charging current limit (100 mA - 1000 mA) and an OLED display for monitoring...

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 insufficient...
