New current sensors have no magnetic circuits
https://www.electronics-lab.com/new-current-sensors-no-magnetic-circuits/
Clemens Valens @ elektormagazine.com discuss about LEM’s new current sensors which do not use the Hall effect make the measurement. Instead they integrate conductors for gradient measurement and provide immunity against the external fields. He writes: Here are some new integrated circuit transducers for AC and DC isolated current measurement up to 300 KHz that […]

AC PWM dimmer for Arduino
https://www.electronics-lab.com/ac-pwm-dimmer-for-arduino/
diy_bloke @ instructables.com has designed an AC PWM dimmer for Arduino: Over 3 years ago, I published a simpel TRIAC AC dimmer for the arduino. That proved to be a very popular design. Yet in spite of the simplicity of the circuit the software needed was a bit complicated as it needed to keep track of […]
Arduino controlled Triac light dimmer
https://www.electronics-lab.com/arduino-controlled-light-dimmer/
diy_bloke @ instructables.com has build an arduino controlled triac light dimmer and describes the circuit and software used to achieve that. It becomes a bit more tricky if one wants to dim a mains AC lamp with an arduino: just limiting the current through e.g. a transistor is not really possible due to the large […]
