The aim of any small signal amplifier is to amplify all of the input signal with the minimum amount of distortion possible to the output signal, in other words, the output signal must be an exact reproduction of the input signal but only bigger (amplified). This can be achieved using a process known as Biasing.īiasing is very important in amplifier design as it establishes the correct operating point of the transistor amplifier ready to receive signals, thereby reducing any distortion to the output signal.Īlso, the use of a static or DC load line drawn onto the output characteristics curves of an amplifier allows us to see all the possible operating points of the transistor from fully “ON” to fully “OFF”, and to which the quiescent operating point or Q-point of the amplifier can be found. Then some way of “presetting” the amplifier’s circuit configuration is required so that the transistor can operate between these two maximum or peak values. Serial.Transistor amplifier’s amplify an AC input signals that alternates between some positive value and a corresponding negative value. Serial.print(" ac voltage ") // this gives name “ac voltage” to the printed analog value Required a.c voltage as specified in the code: Serial.print(m) // this simply prints the input analog value Serial.print(" analog input ") // this gives name which is “analog input” to the printed analog value And also shown on the multimeter as demonstrated in the Video below.Īnalog input value as specified in the code:

Now this voltage value is printed on the serial monitor by using serial commands as explained below. So any random analog value corresponds to (311/1023)*m where m is obtained analog value. Hence:ġ023 analog value corresponds to 311 volt mains supply

304177), first some sort of calculations is performed by using the data obtained in simulation section:Īs seen in simulation photograph, 5v or 1023 analog value is obtained at pin A0 when input a.c voltage is 311volts. To assign variable n to this formula n=(m*. M= pinMode (A0,INPUT) // set pin a0 as input pin M is the input analog value received on pin A0 i.e., Simulation is performed for various voltages between 220 r.m.s to 440v.Ĭomplete ArduinoVoltmeter Code is given at the end of this project and it is well explained through the comments. Hence this circuit can measure maximum 311 r.m.s voltage. On making alternator’s peak voltage 440 (311 r.m.s), voltage on pin A0 was found to be 5 volts i.e.

(Explained in code section).Įxact circuit is made in proteus and then simulated. Arduino then converts this analog value into corresponding mains a.c. Arduino takes this voltage as input from pin A0 in form of analog values between 0 to 1023. Maximum voltage that can be measured is found by simulating this circuit on proteus (explained in simulation section).ģ. Then we get suitable voltage value across 4.7k resistor Step down voltage is obtained on l.v side of transformer which is suitable to use across normal power rating resistors.Ģ. Hence a 5v zener diode is connected to ensure safety of Arduino which breakdowns in case this voltage exceeded 5v.ġ. Hence capacitor is connected to smooth out the a.c signal.Īrduino can get damage if voltage greater than 5v is fed to it. This rectified voltage is not smooth as it contains large ripples which cannot give us any exact analog value.

Check our Half wave rectifier and Full wave Rectifier circuit to learn more about rectification. Hence diode is connected to rectify the step down voltage. Since Arduino do not take negative voltage values as input, we first need to remove negative cycle of step down AC so that only positive voltage value is taken by Arduino. Since this voltage is not suitable as input for Arduino we need a voltage divider circuit which can give suitable voltage value as input to Arduino ** Note: Do connect ground pin of Arduino to the point as shown in the figure or circuit will not work.Īs we are using 220/12 v transformer, we get 12 v on l.v side.
