Campainha Caseira com Som de Telefone Antigo! 📞🛠️ Veja como montar esse circuito super simples usando o clássico CI de melodia BT66T e um transistor BC547. Fiz a montagem no estilo "aranha", soldando direto no alto-falante, sem precisar de placa. É um projeto barato, funciona com bateria de 9V e o resultado é muito nostálgico! 💾 Salva esse vídeo para consultar a lista de materiais que está no finalzinho! Gostou da ideia?
