In this tutorial, we will learn how to move a servo through the values ​​sent by a flex sensor. We can therefore take a step forward in creating robotic joints, such as moving arm hands and many other things.
This is the second time I am writing an article on how to use the fully assembled clap switch that I designed in 2014. This time, I have put several images and written explanation on each of the images so that you can use it easily. At the end of the photo gallery, you can…
In this tutorial, we will learn to make a countdown seven segment display project that counts in a sequence from number 9 to 0. To start counting, you need to press the tactile switch. At the end of counting, it flashes the LED and rings the buzzer for a few seconds.
In this tutorial, we will learn to make a buzzer sound like an ambulance siren and at the same time we will flash an LED. We will learn to change the frequency of the sound to make a two-tone sound. If you want you can insert a potentiometer to increase or decrease the volume.
In this tutorial, we will turn on and off the LEDs sequentially, such as Christmas tree lights.
In this tutorial we will learn how to change the color of an RGB LED connected to Arduino, alternating for two seconds the following colors: red, green, blue, and then orange, yellow, indigo and purple. It is similar to the previous  fade led effect experiment but it is not limited to only one LED but there…
I found this project on Fritzing.org. This is just a simple project for testing a 2 channel relay using an Ethernet shield over an Arduino Mega. In place of LEDs, you can connect 220V AC lamps. If you have not used relay before, check out this article. The Arduino sketch has been compiled and there is…
This is basically a module similar to FTDI/FT232RLbasic breakout board. CH340 is a series of USB bus adapters, that provides serial, parallel or IrDA interfaces over the USB bus (note: CH340G supports serial interface only). The CH340G integrate circuit provides common MODEM signals to allow adding a UART to a computer or converting existing UART devices to USB…
It is just another ‘build your own Arduino’ project. BuildCircuit has worked on similar projects before. The most popular project is a DIY Arduino kit. The DIY Arduino looks similar to the real Arduino boards and uses an FTDI basic programmer to program the chips. The kit that we are going to work on this…
In this tutorial, we will see how to use Arduino with a stepper motor and a joystick. To control the stepper motor we will use the driver control board that can drive up to about 750mA per port, so it is perfect to be used with this motor.
This small module helps you measure moisture of soil. It is a low cost sensor that you can purchase from Ebay. To modify the sensitivity of the soil moisture sensor, just rotate the potentiometer on the module.
This post shows how to build Jaycar’s JIMINI THE CRICKET DIY KIT- PROJECT SC2 #14. It takes around half an hour to build this kit. It is basically a sound sensor. When there is a noise/sound close to the electret microphone, the circuit turns on the two LEDs and produces a chirping sound.
In this tutorial, we will build a digital ultrasonic distance meter. We will use a 16×2 LCD display to view the distance measured. We are using ultrasonic range finder HC-SR04 for this project. The HC-SR04 sensor measures the time taken by the sound waves transmitted after meeting an object that reflects them.
This is the “Skeet” Shooting Game Project from Jaycar. The kit checks your hand and eye coordination. There are 9 green and 1 red LED. There are two switches: one is reset switch and the other is FIRE switch.
This video shows all the steps to build the HEE-HAW Siren Project from Jaycar. The kit is based on NE555 IC. The timer NE555 IC is configured in astable mode. You will hear a hee-haw siren similar to an ambulance and you will see the two green and red flashing LEDs. The kit is very…
This is basically an audio amplifier with one sound channel. Build the kit and connect it to an audio source using a mono jack. You will need two kits to make it stereo amplifier. The source can be your another FM radio project, mp3 project, etc.
This is a sound level meter project from Jaycar. It is based on LM3915 chip. The kit displays the volume intensity via LEDs. It is a visual representation of the audio level. For the maximum volume of an audio source, the yellow and red LEDs light up. For medium sound level, only GREEN LEDs light…
This is a basic electronic DIY kit for beginners. The kit generates a light explosion effect with several LEDs. The scrolling of the LEDs is controlled by CD4017 and NE555. You can adjust the speed of the explosion using a potentiometer. You need basic soldering skill to build the kit. It takes about an hour…
This is a basic electronic kit for beginners. The kit has few SMD component and few through-hole components. Because it has SMD components, it is recommended to use a temperature-controlled soldering iron to solder the CD4060 chip. You need to set the temperature to 300°C, otherwise, you may burn the chip and the kit will…
This is a heart shaped Bicolor multiple LEDs DIY electronic kit with Happy Birthday music tune for absolute electronics beginners. This kit gives you a lot of ideas about bicolor LED, buzzer, music chip, transistors, and resistors.
