Programs, apps, games... it seems like coding is all so digital, isn't it? Sometimes you just want to code something tangible – something you can see or feel, or even taste. Here are three real-world items that use code (and if you experiment with these items, you can program it too), which gives you an idea of how you can experiment and program things too.

1. DIY Light-Up Shoes

Do your own thing with your shoes! You can have modified, custom light-up Vans or Adidas shoes with strobe lighting, lights that 'blink' with each step or maybe even lit up with your own words. There's no bigger flex than saying "I did this myself" when you're complimented on your one-of-a-kind shoes. All you need are LED strips (make sure they're waterproof!) and curiosity... and any additional items, depending on what your end goal is.Would you believe that coding is actually used in such projects? Why not kick it up a notch? Code it on your own, and you could be posting your very own codes online for others!

2. Self-Watering Plants

We all know that tech can improve our lives. Why not take it a step further to simplify gardening? But be warned, you need plenty of research beforehand! What are the ideal conditions for seeds to germinate? When does the plant need more water and how will this happen? How much water is sufficient? These are just some questions you have to think about.Alternatively, you can buy one yourself. Click and Grow makes Smart Gardens for your own indoor herb gardens. As they say, "Grow anything with zero effort"! It comes with self-timers for the lights and you only need to refill the water tank every two to three weeks, depending on the plants you grow.

3. Robotic Woks 

Is it 3020 already? It's futuristic to imagine having robot chefs whipping up consistent meals for us... but this is already a reality – here in Singapore. At Resorts World Sentosa's Ruyi, under Tunglok Group, fried rice is being whipped up by a robotic wok.Can't cook? If you're considering to purchase a robo chef for yourself, MIK Corporation from Japan sells a diverse range of it – from making your own sushi to fried rice too. Of course, it comes with a hefty price tag... unless you can code your own wok!
