The Deek robot is similar to the Arduino pro mini with a ATmega 328. it has no USB interface. i used the Arduino UNO to program the Deek robot, without removing the micro controller ATmega 328 from the UNO board. 1. Connect...
Read out allTabulating the obtained values
The frequency and the sine wave was set by the function generator. The input, output wave forms were observed from the CRO. The conditions taken were a 50KΩ , 1KΩ and a current source. The input was fed to the 2.1...
Read out allNPN Transistor as an Amplifier :
We wanted to use the transistor as an amplifier. The input voltage at the base was 3v. Two resistors, one at the emiiter(R1) and the other at the collector(aR1) were connected. 9v supply was given at R1. Constraints : We wanted head...
Read out allPNP Transistor as a Current Source
We wanted to use a transistor as a current source. Two resistors, one at the emiiter(R1) and the other at the collector(R2) were connected. A voltage divider circuit with a supply of 9v was connected at the base that could supply certain...
