Arduino USB

Interfacing(USB – RS232 – I2c -ISP) Projects / Ibrar Ayyub

LOG: Made a correction/modification Step 3 and added a picture step 5. So many Arduino users have RBBBs(Really Bare Bones Board (Arduino)) or Anarduinos or Boarduinos that could use a USB interface to program and power them but don’t want to spend $15-20 for a USB BUB or FTDI cable. This Lazy Old Geek is

AC Dimmer Circuit: 46

Interfacing(USB – RS232 – I2c -ISP) Projects / Ibrar Ayyub

Green wire is zero_cross signal, goes to Arduino digital pin 2 in. Yellow wire is light dimming signal, comes from Arduino digital pin 11. The LED on board should dim or fade along with the AC light source. Fading will not work until AC power is connected, it depends on the zero-cross info from the

Burning the Bootloader on ATMega328 using Arduino UNO as ISP

Interfacing(USB – RS232 – I2c -ISP) Projects, Projects / Ibrar Ayyub

I had one remote controlled project that needed an Arduino running 24/7 but I didn’t want to leave my $32 Arduino UNO, so I decided to buy some pieces and created my own Arduino. The most important part was buying the microcontroller. These were my options: ATMega328P-PU with Optiboot ~ $5.50 (Sparkfun) / $5.19 (Digikey)

Arduino HC-SR04 How to use Ultra Sonic Sensor

Interfacing(USB – RS232 – I2c -ISP) Projects, Projects / Ibrar Ayyub

Arduino HC-SR04 The Arduino HC-SR04 is different from most of those commonly seen on the market, which have 4 pins compared to 3 pins. But the operation principle is the same, transmit signal, and depends on when the signal is received to estimate the distance. Arduino HC-SR04 not only inexpensive but also practical, use a

An amplifier for Arduino

Interfacing(USB – RS232 – I2c -ISP) Projects, Projects, Sound – Audio Projects / Ibrar Ayyub

For my project, the Arduino output is not enough so digging on the net and asking to a friend some help, I managed to build an amplifier to feed my 3 computer fans. This circuit can be used as an amplifier to switch on and off a DC motor and to regulate its spinning speed
