This is the circuit of a robot published in the June 1992 issue of Radio Electronics magazine. The sensors are used to drive 2 motors with reduction gears. The power is provided by batteries.
The frequency of this oscillator depends on the crystal used. The transistors are general purpose. We...
You can measure capacitances across a large range of values using the AC Power line frequency as...
The circuit of the figure serves the same purpose as the previous one (CB5057E), but has a...
