Linkit ONE Touch LED Using Atmega


This instructable will guide you to glow an LED using a touch sensor which means that the LED will glow when you touch on the probe of the sensor.

Linkit ONE Touch LED

The project uses the Mediatek linkit one connected to a touch sensor and an LED. As soon a touch is detected, the output goes high which is detected by linkit one thus the LED glows.

So let’s begin with this project………

Stp 1: Parts Required

Parts Required 1

The following parts are required to make this project:

– Linkit one
– Battery
– Breadboard
– Touch sensor
– Transistor
– Jumper wires

Step 2: Connect the Battery

Connect the Battery 3

The first step or the easiest step is to connect the battery to linkit one. Simply plug it to it’s socket.

Step 3: Connect the LED

Connect the LED

Next step is to connect the LED. You can follow the images provided above. The digital pin that you need to use is- pin 2.

Step 4: Connect the Sensor

Connect the Sensor

Connect the touch sensor to linkit one as per the following:

– Vcc ——————— 5v of linkit
– Gnd ——————— Gnd
– Out ———————— A0

Step 5: Upload the Code

Upload the Code 2

Upload the code provided below to your linkit one. The switches should be in SPI, USB and UART positions.

void setup()
pinMode(2, OUTPUT);
void loop()
if(analogRead(A0) > 600)
digitalWrite(2, HIGH);
digitalWrite(2, LOW);

Step 6: Test

After completing the project, switch in on. On touching the probe of your sensor with your hands, you will observe that the LED lights up!

So, this is the end of this instructable. Thank you so much for watching!!
