Using 5 V relays, this circuit can be used as a control shield for microcontrollers. The circuit uses relays, and the motor voltage is independent of the control voltage.
The critical component of this project found in a 1993 publication is the LM12 integrated circuit....
We found this circuit in an old publication dealing with operational amplifiers. The circuit uses...
Within a range of values, this circuit converts input voltages into corresponding currents. The...
