I'm glad to introduce you a launchpad with couple interesting features and comfortable interface for cooking lovers.

You will need:

• Arduino UNO
• DHT22 sensor
• 16x2 seeed LCD (if you use any other LCD you have to import a relevant librery)
• Relay 9v to 220v
• Switch x2
• Resistor 220 ohm x2 (to avoid switch bouncing)
• Greeb LED
• Red LED
• AC power adapter 9V
• Heating element

connect all your periferia as described below:

• DHT22 data pin to port 2
• UP button pin to port 12
• DOWN button pin to port 13
• Green LED (anode) to port 3
• Red LED (anode) to port 5
• Relay data pin to port 4

!!!IMPORTANT!!!

Do not connect relay VCC pin to 5V port of arduino to avoid overload. Insted you may solder it to DC jack "Tip" connector or use special shield.
