The full scale deflection of the meter itself is a relatively tiny 50 ... mentioned use for finding current peaks and troughs in analogue circuits. The MF47 will stay on my bench as a much lighter ...
Analog multimeters use a needle indicator and scale to show readings, while digital multimeters (the dominant style today) show numeric readings on an LCD, LED, or other electronic display.
Whereas a typical scale would then simply show the resulting number on an LCD display, [Mirko] decided to use a moving coil meter driven by the Arduino’s analog output. That meter was originally ...
