Non Invasive 100A current clamp - Analog A0 0-5v Using a voltage divider and Emonlib for Current Rms and Apparent power readout.

Today we will be designing a Multipurpose Power Supply. The Power Supply will be an Arduino UNO Power Supply Shield which will output multiple voltage range such as 3.3V, 5V and 12V.

Features common to Arduino R4 – ‘WiFi’ (€25, below) and ‘Minima’ (€18, right) IO connections are in physically similar positions to Uno R3, and IO remains 5V.

Connect the negative of +5V battery to the pin 4 of ATtiny13 A potentiometer is connected to the pin 7 (PB2) of the ATtiny13 and the control wire of the servo motor is connected to pin 5 (PB0).

Laser diode are available in various sizes and can be interfaced with Arduino Uno using photoresistors, photodiodes, sensors & detectors.

He further explains that, with the Arduino Uno, you can remove the reference capacitor from the circuit, and simply use the stray capacitance present in the board and microcontroller, which can be ...
