This circuit allows control of loads of up to 1 A with voltages from 3 to 15 V. The transistor must be equipped with a heat sink and the power supply must not be of the type without a transformer.
This high-gain digital amplifier uses general-purpose transistors. The supply voltage is logic...
We found this circuit in the March 1993 issue of Electronis Now magazine. The circuit uses common...
Using an LDR as a sensor and an operational amplifier this circuit was found in the Encyclopedia of...
