Arduino Nano ile Waveshare E-ink Ekran Hassas Voltmetre (0-90v DC): 3 Adım

2024 Yazar: John Day | [email protected]. Son düzenleme: 2024-01-30 13:16

Bu Eğitilebilir Kitapta, E-Kağıt Ekranında 90 volt DC'ye kadar hassas voltajları görüntülemek için Arduino Nano, voltaj bölücü ve ADS1115 ile 2,9'' Waveshare E-Kağıt ekranı kullanıyorum.

Bu talimat, önceki iki projeyi birleştirir:

- Arduino Volt Metre (0-100V DC) - Sürüm 2 -

- Arduino ile E-Kağıt Görüntüleme Kısmi Yenileme -

Gereçler

Kullanılan Malzemeler:

1 x Arduino Nano -

1 x Waveshare ekranı -

AIN0 Gerilim bölücü

Voltaj bölücü için bu sefer 680Kohm ve 10Kohm dirençler kullandım. Daha iyi doğruluk için her zaman direnç değerlerini ölçerim.

Gerilim bölücü hesaplamaları, farklı direnç değerleri kullanmak istemeniz durumunda hesaplamaları otomatikleştiren bu e-tabloda mevcuttur: Link to Google Sheet. Lütfen dosyanın düzenlenemez olduğunu, değiştirebilmek için indirmeniz veya sürücünüzde bir kopya oluşturmanız gerektiğini unutmayın.

2. Adım: Kodlayın

Ekranın ve ADC'nin kodu oldukça büyük ve ekranda büyük karakterler kullansaydım arduino'da yeterli bellek olmazdı.

Bunu çözmek için, metni içeren bir resim oluşturarak ve ardından resmi arduino tarafından okunabilen koda dönüştürmek için bu çevrimiçi aracı kullanarak metni koda dönüştürdüm:

Hala bazı yazı tipleri ve karakterler kullandım, ancak bellekten tasarruf etmek için pil voltajını ve şarj yüzdesini görüntülemek için yalnızca sayıları içeren bir yazı tipi kullanıyorum.

Bu kod, 90v'de pilin şarj edildiğini ve 0v'de pilin tamamen boş olduğunu varsayarak pilin voltajını ve şarj yüzdesini görüntüler. Bu, ihtiyaçlarınıza göre değiştirilebilir.

Adım 3: Hadi Test Edelim:)

Sonuçlardan oldukça memnunum.

Gerçek voltajdan minimum sapma (0,2 volttan az) ile yaklaşık 9v ila yaklaşık 85v arasında bir dizi voltajı test edebildim.

Güzel bir muhafaza içine paketlendikten sonra, bu, çok parlak ortamlarda okunabilen hoş bir küçük volt metre yapmalıdır:).
