Linkit ONE Touch LED

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.

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………

Step 1: Parts Required

The following parts are required to make this project:

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

Step 2: Connect the Battery

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

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 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 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);
