In the previous blog post, " Joystick controlled DC motor with Arduino and TIP122 ", we showed how to control the speed of a DC motor using a joystick and the TIP122 transistor. However, we only utilized the x-axis of the joystick for cont…
Controlling a DC motor with a joystick is an easy and fun project that can be done using an Arduino board and a TIP122 transistor. In this Arduino dc motor tutorial , we'll walk you through the steps to set up Joystick to work with Arduino and s…
Here Arduino signal generator using ISR(Interrupt Service Routine) is demonstrated. In the previous tutorial Arduino 8MHz Variable Frequency Generator the interrupt service routine was not used but here we will use the interrupt service routine to …
Here it is shown how one can generate signal with adjustable frequency upto 8MHz using Arduino Timer in CTC mode. There are basically 8-bit or 16-bit timers in Arduino Uno, Arduino Nano, Arduino Meg2560 etc. Depending upon whether 8 bit or 16 bit …
CTC(Clear Timer on Compare Match) mode is one of four wave generation modes in Arduino Mega 2560 and other Arduino boards. The other wave generation modes are normal mode fast PWM mode and phase correct PWM mode. CTC mode is useful for generating sq…
Here it is shown how audio can be generated using Arduino, R-2R DAC(digital to analog converter) and LM358 operational amplifier. The audio is first recorded and put into ROM of the Arduino. Then this audio is output is sent to R-2R ladder DAC which…
Here it is shown how to output recorded audio using Arduino Mega 2560, R-2R DAC and using electronic amplifier using transistors. The audio is put into the Arduino Mega ROM memory. The R--2R is a simple resistors based digital to analog converter. T…
