The circuit uses a potentiometer in parallel with a +5V DC source in order to provide a variable voltage to the micro-controller (Figure 8). The micro-controller should then change the motor speed according to the voltage level received from the sensor, a range of 0 – 4.7 volts DC.

Linear Regulators. The LM7805 is a voltage regulator that takes a DC voltage (in a range of up to 30 volts and gives a constant 5 volts DC. This is a very simple and great component since it is very simple to implement. Figure 2: LM7805. L7815CV is another voltage regulator and both LM7805 and L7815CV look the same and work the same.

REGULATED DC POWER SUPPLY
Voltage regulator ICs are available with fixed (typically 5, 12 and 15V) or variable output voltages. They are also rated by the maximum current they can pass. Negative voltage regulators are available, mainly for use in dual supplies.

1. Fixed output voltage regulator . 1.1. DC parameters. Explorations. Supply the schematic in Fig. 1. with a DC input voltage, VI=8V and use the jumpers to connect J1 with J2, J11 with J12 and J14 with J15. Measure the output voltage VO with a voltmeter and compute the value of the output current IO (RL=47Ω). Write down these values.

DC voltage stabilisers. Many simple DC power supplies regulate the voltage using a shunt regulator such as a zener diode, avalanche breakdown diode, or voltage regulator tube. Each of these devices begins conducting at a specified voltage and will conduct as much current as required to hold its terminal voltage to that specified voltage.
